Just my opinion but Cain was a little disappointing

I’m rewatching season 10 and between 9 and 10 Cain was only in 2 episodes. Don’t get me wrong I like omundsons portrayal of Cain he did a great job with it. I just wish they made him a bigger part of the whole thing. And I know the big picture was all about the mark of Cain and deans struggle with it but like I said Cain definitely could’ve had a bigger part in it rather than here’s the mark and the next episode he’s in it’s time for him to bite the big one.
