It was the talk of San Diego Comic-Con: how will former angel Castiel cope with the filth of being human? It won’t be easy but it will be fun. Misha Collins teased a “great bathroom scene” where he will have to figure out basic biological functions. Tonight’s lesson: laundry at the local Hillside Laundry. [Update: Later scenes suggest Castiel doesn’t do laundry. Heborrows it to give him a change of clothes. Supernatural filmed Castiel (Misha Collins) rummaging through garbage cans behind the Ovaltine Cafe in the Downtown Eastside and hiding behind bins in the rain and then later in regular clothes giving change to a woman in Chinatown ].
