Monday. Ten days since the Omnitrix. Silas sat in AP Chemistry with his notebook open to the wrong page the page where he'd been documenting pulse patterns instead of the electrochemical equilibrium notes he was supposed to be taking and tried to look like he was paying attention.
He was mostly paying attention. The other part of his brain was running the pulse pattern problem he'd been working since Saturday morning. He'd been feeling the watch communicate for ten days and had only started writing it down properly in the last three. The notebook now had a full page dedicated to it, tucked between his Okafor notes and his alien profile documentation, with a header he'd underlined twice: PULSE LANGUAGE.
So far he had four confirmed entries.
One slow pulse, four-second interval: resting state. He'd known this one since night one, had just never written it down formally.
Two quick pulses close together: attention. Pay attention to something nearby. He'd noticed this one on the bus three days ago when a news alert had run about a building fire in Suicide Slum. The watch had done it twice before he'd looked at his phone.
Three short pulses: urgent. This one he'd worked out the night he went out as XLR8 the convenience store. Threat nearby. Do something or don't but be aware.
Four slow pulses, deliberate spacing: acknowledgement. He'd felt this one after the camo mode discovery with Hamilton and again when he'd pressed the two band points deliberately after that. The watch hearing him. Confirming it had received something.
'There are more. I know there are more. The timer warning is different from all of these rapid continuous, not a counted pattern. And there's something it does when I revert that I haven't pinned down yet.'
Mr. Okafor said something about electrode potential and Silas wrote it down without looking up from the pulse pattern page, switching notebook sections with the practice of someone who had been living a double life for ten days and was getting better at the logistics of it.
"Foster," Mr. Okafor said.
"Electrode potential decreases as the reaction proceeds because the concentration gradient that drives the cell diminishes," Silas said, without looking up.
A pause.
"Correct," Mr. Okafor said, with the tone of someone who had been hoping to catch a student out and was mildly disappointed. He moved on.
Devon, beside him, leaned over slightly.
"How do you do that?" Devon whispered.
"Do what?" Silas whispered back.
"Answer correctly while writing something completely different," Devon whispered.
"Practice," Silas said.
"That's not a real answer," Devon said.
"It's the only one I've got," Silas said.
....
After school. The freight yard. Same fence panel, same loose post, same cracked concrete waiting on the other side.
Silas stood in the center of the yard with the dial on position two and spent a full minute just looking at the silhouette on the raised faceplate. He'd been putting this one off. The profile was quadrupedal, low to the ground, with no visible facial features in the outline. No eyes. No mouth. Whatever sensory system it used wasn't the kind that showed up as features on a face.
'This one is going to be the most disorienting one yet. A body that doesn't look back when you look in a mirror. A body that navigates without eyes.'
He pressed the dial.
The form that arrived in the freight yard was low and compact, maybe four feet at the shoulder on four legs, covered in a tough brownish hide studded with what felt like dense quill clusters along the back and haunches. No eyes. No mouth. The face if you could call it a face was a broad flat expanse of sensory skin, and the world as it hit that skin was not vision.
It was everything else.
Sound arrived with a precision that made the word hearing feel inadequate. Silas could identify the individual wing beats of the pigeons on the north building eave, the specific frequency of the loose fence panel vibrating in the wind, the footsteps of someone walking on the far side of the perimeter wall weight, pace, distance, all of it arriving as clear data without a conscious request. Smell was worse. Or better. He wasn't sure. The freight yard had been a working industrial site for forty years and every layer of that history was present and specific, diesel and rust and old rubber and something organic he couldn't name and didn't want to.
'Okay. Okay, that's there's a lot happening right now. Don't panic. You've done this before. Let the body have the first few seconds.'
He stood still. Let the sensory system do what it knew how to do. Slowly the data stopped feeling like an assault and started feeling like information. The yard assembled itself in his mind not as an image but as a map spatial, detailed, built from sound and scent and a faint vibration sense through the four feet flat on the concrete.
'You're navigating. Without eyes. And it works.'
He moved. The body was fast on four legs, faster than he'd expected, the low center of gravity making the turns sharp and clean. The quills along his back shifted when he accelerated, not as weapons but as sensors, reading the air displacement around him with an accuracy that fed directly into the navigation map.
He ran two laps of the yard, testing the turns, testing the stops, testing what happened when he held still and just listened. At one point he went completely motionless for ninety seconds and by the end of it he could have told you the location of every living thing within two hundred meters the pigeons, a rat behind the loading bay, a cat on the warehouse roof, a person jogging on the street beyond the perimeter, their footstrike pattern and approximate weight.
'This form doesn't fight. This form finds. It's a tracking machine dressed up as an animal.'
The timer pulsed its rapid warning. He'd been so absorbed in the sensory experience he'd lost track of the countdown. He found the corner of the yard furthest from the fence and waited for the reversion.
Silas stood in the freight yard, human again, with the recharge lock cycling red and the ghost of extraordinary sensory precision fading back into ordinary human awareness. The yard suddenly seemed very quiet. Very small.
'That's the one I'll name later. I need to sit with it first.'
....
He was checking the recharge status the hourglass still red, maybe six minutes left in the cycle when the sound arrived.
Not the Omnitrix pulsing. An actual sound, from outside the freight yard perimeter. A deep structural groan, the kind buildings made when something was wrong with them, followed by the sharper crack of concrete under stress, followed by voices a lot of voices at once, the specific acoustic texture of a crowd reacting to something sudden.
Silas was through the fence gap and on top of the perimeter wall in ten seconds, pulling himself up to see over.
Three blocks east. A construction site the new residential tower going up on Hob's Street had shed a section of scaffolding along its eastern face. The scaffolding was down, a debris field across the pavement below, and three or four workers were visible on the exposed upper floors with nowhere obvious to go. The crowd on the street had pulled back. Someone was screaming. A police cruiser was already there, lights going, the officer on his radio.
'Recharge lock. Red. I can't transform. I can't do anything from here except'
He heard it before he saw it. Not a sound exactly more of an absence of sound, the way a space organized itself differently when something was moving through it at velocity. Then the blue and red.
Superman came from the northwest at an angle that suggested he'd been somewhere else entirely twenty seconds ago and had adjusted course. He hit the scene without slowing one clean deceleration from impossible speed to a hover above the compromised scaffolding assessed it in what Silas estimated was about two seconds, and then he was moving.
Four minutes. That was how long it took. Silas sat on the perimeter wall with his recharge lock still cycling red and watched Superman clear the debris from the pavement in under ninety seconds, stabilize the two most at-risk workers on the upper floors simultaneously, lower them both to street level with a precision that looked effortless, conduct a scan of the building structure that Silas could identify by the way Superman tilted his head and went very still, and then speak to the construction site foreman in a brief, calm exchange that resolved whatever needed resolving before the fire department arrived.
Four minutes. Start to finish.
Then he was gone. Not dramatically. Just no longer there, the space he'd occupied now ordinary air again, the crowd reassembling on the pavement, someone already taking photographs of the debris field.
'That's what this city has. That's the standard.'
Silas sat on the perimeter wall for a moment longer. The recharge lock clicked green. He looked at the Omnitrix faceplate, raised and active, the hourglass glowing steady.
'Four minutes. He handled a multi-casualty structural collapse in four minutes. I spent eleven minutes flying around looking at the city for fun.'
He climbed down from the wall. Stood in the alley. Thought about that for a while.
'You're not him. You're not trying to be him. But you should probably know what you're working next to.'
He walked home with his hands in his pockets and the Omnitrix in camo mode and the ordinary evening Metropolis crowd moving around him, none of them knowing what had just happened, most of them already looking at their phones.
....
His mother wasn't home yet. He sat at the kitchen table, notebook open, and documented position two's physical profile first. Quadrupedal. Compact. Quill clusters along the back and haunches functioning as additional sensory receivers. No visual system. Navigates through a combination of echolocation, scent mapping, and ground vibration reading. Speed on four legs exceeded his XLR8 acceleration in the first twenty meters of a straight run different kind of fast, lower and more agile rather than pure top-end velocity.
He wrote about the sensory experience separately, in more detail than usual, because it had been the most disorienting form yet and he wanted to get it down accurately. The way sound arrived as spatial data. The way smell had a depth to it that human smell didn't. The way the world assembled as a map rather than a picture.
Then he sat back and thought about what to call it.
Every other form had given him something in the naming. Infernoid the fire and the mass of it. XLR8 already right. Brawler what it was built for. Jetray the flight, the sleekness, the feeling of permission.
Position two was a hunter. Not aggressive. Not built for confrontation. Built for finding. For reading the world with a precision no visual system could match, for tracking, for knowing exactly where everything was before committing to anything.
'It's a hound. That's exactly what it is.'
He wrote at the top of the page: HOUND.
Looked at it. Felt right.
He turned to the pulse pattern page and added two more entries he'd confirmed today. The rapid continuous pulse during the form session timer warning, already knew this one but it was different in Hound because there were no eyes to look at the countdown panel. The pulse had felt more urgent, more insistent, like the watch knew he needed extra notice without the visual reference. And the single firm pulse after recharge completed clean and deliberate, a full stop at the end of a sentence.
Six confirmed patterns now. He wrote them all out in a clean list.
He was still writing when he heard the key in the front door.
"How was the test today?" Denise asked, setting her bag down and moving to the kitchen.
"Which test?" Silas asked.
"AP Chemistry. You mentioned it Friday," Denise said.
"Oh. Good. Ninety-one I think," Silas said.
"You think?" Denise said.
"Pretty sure. Okafor doesn't post grades until Wednesday," Silas said.
She looked at his notebook. Not reading it just noting its existence, the way she always did.
"Anything today?" Denise asked.
"Tested position two. Named it Hound. Saw Superman handle a scaffolding collapse on Hob's Street in four minutes," Silas said.
She filled the kettle. Turned it on.
"How'd the form go?" Denise asked.
"Weird. No eyes. Navigates by sound and smell. It was a lot, at first. Got better," Silas said.
"And Superman?" Denise asked.
"Four minutes," Silas said.
She looked at him then. Just briefly. The look that meant she understood exactly what he wasn't saying.
"You're not him," Denise said.
"I know," Silas said.
"You're not trying to be him," Denise said.
"I know that too," Silas said.
"Good," Denise said, and poured two cups.
