I kinda mentioned this in my prev post (here) but Doc uses diferent mobility aids due to his varying ability to stand up by himself.

Mid relapse it's usually a wheelchair, while during remiting periods, he's normally fine with just a cane. Lippmann has painted little shrews onto his wheelchair because they're Doc's favourite animal. He actually has several canes, but usually he uses a single point offset cane that Albatross has covered with stickers (offset canes are designed to reduce strain on the wrist!!)

Lippmann, Piano Man and Doc do pilates together when Doc feels up to it. It helps him stay active while not pushing himself too far.

His favourite season is winter but he CANNOT handle the cold. It just absolutely ruins him. He seems determined to not let this stop him. If someone tries to force him back inside, he will pelt them with any available snow. Chuuya did not know this. Albatross found it hilarious when he came back inside caked in snow and with the eyes of a boy completely defeated.
