They would be like very two annoying peas in a pod! Except I'm not how sure Balthazar would be amused by some of Gabriel's crazier pranks and if you start singing My Heart Will Go On so help you.

I've never really bounced him off of a Gabriel before so it would definitely be an experience if I brought him in! I may PM you once I've actually picked, so thank you so much for being helpful 'v'
