"You buy me a costume, I'll dress up as whatever you want me to when it's just us in our cabin hideout. Until then, you'll just have to deal with my drop-ins in my normal people clothes." Whenever he shows up. To be present. He rocks to his feet at the mention of a chore that needs doing.

Because it's useful. He can be of use. Even if it's just in little ways. Being effectively on leave himself has been actually really shitty in terms of needing things to do with himself, even as distraction. "I'll take care of it. Hell, give me a list of chores, I can make sure shit gets done."
