[ He'll have to gather up some other people's hands as an offering, because he needs the two of his to 1) rub at his arm, and 2) pat her on the head- this turns into a light noogie, not enough to hurt, but enough to mess up her hair more than it already is after tumbling out the window and now drenched in snow. ]

[ She will die by his hands before the year is over, or come close to it... But, even if he doesn't admit it out loud, this is something he's really missed too. Back at the orphanage, he really only had Ellie and Minako to play with, and in a huge academy like this one, where he's hunted down and dragged to class instead of skipping out like he used to do, living in the dormitories, eating with people, expected to make friends... he hasn't done much of that at all. Strangers don't push strangers out of windows, so he's missed being able to do these sorts of things with Ellie.

He drags the soggy rug over and flattens it out so he can lie back on it, half buried in this snow pile that they should maybe get out of someday. ]
