I Don't Like Whenever He Does Talk About His Father Sometimes It's Treated As A Joke (Bernadetta Support Sadly) - Tumblr Posts

Adding on to @vonbergerpants claim about Caspar in hopes Being with his father is a bad thing for him, Caspar already thinks he's worthless and "expendable" already imagine that to 2x when he's with the guy everyday along with his brother. Plus taking Linhardt away from him doesn't make the situation any better the person who has always treated you as a person, never having to talk down to you or make you feel ashamed of yourself is gone (regardless if dead or recruited) he thinks that Linhardt could've been tortured or worse refusing to sleep because of the thought thinking if he was only stronger than this would've never happened in the first place. When Linhardt refuses to go with him that (most likely) made his mental stability far worse believing that Linhardt betrayed him and in the end no matter what he always thought that he was weak.
