The hug is probably the biggest surprise that Togusa has ever gotten out of Mari, but to his credit, he doesn't hesitate before raising his arms in return. He gets it. He's still here. They're still friends. This Retrospec crap isn't going to come between them.

Even if some of the unanswered questions are coming from each other now.

"I believe you." Firmly. "And know that it's true for you, as well."

He steps away, so he can look her in the eye. "I remember what's important, even through the rest of this."

Togusa will find a way to excuse himself before he overstays his welcome, give the both of them the time they need to ruminate on what they've learned tonight. In the end, it doesn't really matter what Mariko knows about "him" does it?

As he leaves, there's a ghost of a touch over that hole in his chest, reflexive. Maybe something matters.
