Firstly, this looks amazing. Second, I'm gonna make an OOC
LIAM could have been a part of SABINE's exorcism? He definitely would have needed help, I don't know if MJ is still interested in CHRISTIAN and Liam knowing each other, if so it'd be badass if they had teamed up in the South somewhere?
REX might have run into AUSTIN in the past if he's not gone through proper routes investigating? Could've almost shot him or something on a private property after getting a complaint?
