Charlie asked Husk to check on Alastor(you) because he was acting a bit under the weather. But he was actually upset because of Husk. Husk didn't remember but when he was alive, he was best friends with Al and was basically a brother but died before Al. So he forgot about him and later hated him since he owned his soul. Husk walks in on Alastor crying

Husk:Alastor, what's got ya down...? I don't care but Charlie does.

Alastor:Why can't you remember...?

Husk:What're you talking about?
