I know everyone wants Gabriel back, but I would much rather have Balthazar back. There was so much potential with his character and I wanted to see him interact with Cas more. He could have been kind of like Crowley was for dean

*slams fist on the table* NOW THIS IS WHAT I’M TALKING ABOUT!
Okay, no shade to people who like Gabriel, but I will always, ALWAYS prefer Balthazar. Like, Balthazar love Cas. I don’t care if you say it’s platonic or familial or romatic, he loved Cas. He was an amazing friend, too, reaching out to other people when he knew he couldn’t help Castiel and he thought there was something really wrong going on.
Not only that, but the two of them had history. We’ll probably never know the extent of that history, but we know they had it. Like, Balthazar faked his death (how does an angel do that? Why does an angel do that?) and Cas mourned him! And then he was kinda pissed when Balthazar showed back up but they really did have a relationship that screamed closeness. They knew each other really well and I wish I knew what that relationship entailed.
And, personally, if I write Cas with a brother or a wingman (puns) it’s always going to be Balthazar. They just go on so well!
Okay, I’ll shut up now. But yeah, Balthazar and Cas have a very interesting relationship and I want to see Balth be a good bad influence on Cas.
