[At the very least, Luke seems to be able to keep to himself. It's not like he would know how to talk to Yuri anyway, he's fine being quiet. Hopefully quiet enough that he isn't a bother. Though he's starting to regret sitting... it was hard to stop thinking about the fact that there's no way Yuri actually wanted him to stay and just offered out of some habitual kindness and now no matter what he did he would be intruding.

After a few minutes of sitting in silence, he gets up.]
