Jade's experience was almost the same as his in terms of inheriting memories and power from the simulation.
With her intelligence and wisdom as a Human Progenitor possessing the X-rank Superintelligent Brain innate talent, it was impossible for her not to notice something.
This was one of the main reasons why Zayne wanted to talk to Jade first before his train crewmates.
Even if he were to explain that he had used an artifact or ability to perform his escape plan, Scarlet and the others wouldn't doubt his claims. After all, from what they've experienced, it was indeed like dying and being resurrected in another universe.
But for Jade, the experience was different. She wasn't revived or summoned by him, but her memories and power were inherited by the real world Jade!
In other words, it's like Jade used Zayne's Doomsday Life Simulator System to experience a simulation. The only difference was that she didn't possess any simulation talents or the system.
