Hilarious that the final scene barely moved the needle on Tommy's scale of awkward romantic moments! As long as the new pastor is divorced rather than currently married, I don't see a big problem with a congregation member flirting with him, particularly since she didn't know he was her new pastor at the time.
I know it's TV so Carlos and TK have to treat the former's marital situation as a big dramatic reveal, but they do know they could hold the wedding at the venue they want without a license and just make things official with a justice of the peace later on once legal hurdles have been cleared, right?
