Not everything is as it should be. Mohinder's shaken, Mohinder's upset. The buzz of his thoughts tend to range from wondering how he'll tell Molly what happened to never being able to see Matt again on the sofa watching the game. He blames himself, he blames Matt, he blames Sylar's nature -- but not Sylar -- and backs off of that train of thought almost immediately. He's worried for his lover, he;s worried about this place. There's also curiosity at how these scans will look, a faint desire to have known how Matt's brain looked before Sylar poked through it---

And bruising. A lot of bruising. It's difficult to really see it, but the edges of his memories seem tender, as if someone's been plundering them. And had been for days.

Mohinder's violation at the hands of his friends becomes clear. They've left traces. There may not be a rape kit for the mind, but Mohinder still is showing the classic symptoms of it.
