The draft and the tornado may be good ways to get him in action and still be with people. It would keep his mind focused, but still troubled and with him unwilling to deal with it.

Alternatively, he could also continue to research and call some friends to help him with it, and still have people notice he has a loose screw someplace because of losing Joshua. His closer CR beside him could be of help for that.

Fortunately for him, if we get the reserved Chiba, he's finally going to have a therapist!
