Okay, I gotta know
Do you have theme songs picked out for the two of your little guys
I gave this some thought over the day, and I think I have some selections! It was way harder to find songs for Joseph because of my music taste though, PSH
So:
For Joseph, I can link him to Karma by OR3O. It's got that positive mental attitude vibe and not letting hardship beat you down, which I think is very fitting for the type of person he is. Also the message that "karma is what you make" fits in with his faith in God. Everything happens for a reason, and divine justice will be eventually served to everyone.
For Lavy, I have a couple of contenders. Blood from MCR and Heaven Says (Gameplayah cover). Blood is mainly for the trans atlantic accent, but also the theming of blood can co-incide with them being a gunman and how it'll never be enough because their job won't ever truly conclude. It can also translate to their duties as a demon while trying to corrupt people. Heaven Says is Lavy's gripes with God's judgement and being deemed a sinner.
This was a fun one to answer, it made me think!
