I drove home from Karen's apartment that night with my hands too tight on the wheel, replaying the moment over and over, trying to decide whether I'd imagined the weight in it or whether it had been exactly as deliberate as it felt.
Markus had warned me. I'd dismissed it, told myself I was protecting a grieving, lonely woman from an accusation she didn't deserve, and now I was sitting in my car outside my own apartment unable to make myself go inside and face Alex with the truth of what had just happened.
He was already home when I got there, curled up on the couch with a book he wasn't really reading, the particular kind of waiting he did on nights when his shifts ran long and he wanted company more than sleep.
"You're quiet," he said, the second I sat down beside him. "Everything okay with Karen?"
The question landed like an opening I should have taken immediately, and I let it pass anyway. "She's fine," I said. "Dinner was nice."
I told myself, in the moment, that I was protecting him — sparing him an ugly conversation about his sister that might not need to happen if it never repeated itself. I told myself a version of the same lie I'd been telling since the restaurant, dressed up as kindness instead of cowardice.
Alex studied my face for a moment longer than the answer warranted, the way he always did when something didn't quite track, and then let it go, leaning into my side instead of pushing further. I should have been relieved. Instead, the silence sat in my chest like something rotting.
I called Markus the next morning, mostly because I needed to say the truth out loud to someone, even if I couldn't manage it with the one person who actually deserved to hear it.
"She made a move," I said, without preamble, the second he picked up. "Last night. At dinner. She held my hand too long, said something about feeling like she'd missed her chance at ever having what Alex has, and I—" I stopped, searching for the right word. "I pulled away. I told her I should go. But I haven't told Alex."
Markus was quiet for a moment, and when he spoke, there was no satisfaction in his voice, no I-told-you-so I might have deserved. "What are you going to do, sir."
"I don't know," I admitted. "If I tell him, it could destroy his relationship with the only sibling he has left, over something that might just be loneliness and bad judgment on her part. If I don't tell him, and it happens again—"
"It will happen again," Markus said, with the kind of certainty that came from decades of reading people more accurately than I apparently could. "People who cross a line once rarely stop at one attempt, sir. Especially when the rejection only confirms what they already feared — that they're never going to get what they want through honesty."
"You think she'll try again."
"I think you should tell Alex," Markus said, "before she does it for you, in a way that makes you look like you were hiding something far worse than the truth actually is."
I knew he was right. I knew it the way you know things you don't want to act on yet, turning the knowledge over and over without quite letting it move you toward the harder conversation it demanded.
I didn't tell Alex that day. Or the next. I told myself I was waiting for the right moment, gathering the right words, when the truth was simpler and considerably less flattering: I was scared. Scared of hurting him, scared of damaging something I'd only just learned how to value, scared that telling him the truth about his sister would somehow make me the villain of a story where I'd actually tried, however imperfectly, to do the right thing.
Silence felt safer. It wasn't. It rarely is, in stories like this one, no matter how reasonable it feels in the moment you choose it.
