Just curious you think he got to shave while in prison? A couple days without proven shaving and no shadow? ~ He was imprisoned for 2 years. Apparently, Jotun's do not have facial hair, thus Odin and Thor with beards and Loki without!
"Loki by Loki" by Tom Hiddleston :D . If Happy Hiddles doesn't make you happy, then you are beyond the help of mortal men >>> I just want to protect this man and huggle him and keep him safe from corruption. In the least creepy way, of course.
