You know what? I'm gonna catch you up on the new members:
Evil ROB: Event by PooBone that I turned into a new member
Stephen Scotch: Team Pigmask Sent him here, thinking he would f**k shit up... Ended up backfiring because he and Boris were great friends
Dmitri and Grigori: Impressed that Team Wheatley was able to capture Justin Case
George B. McClellan: Rival of Abraham Lincoln
Feed Me: Rival of Snake the Jaik
Clay Puppington: Wants revenge on the Morshu Police Department
CDi Ganon want to make Team Wheatley a genuine threat
Marcus Leviathan: Happened on the fly... He had just arrested "Fake Astley" and Stop Cop saw him as a great replacement for Lee (Who left because he thought Wheatley went too far)
Badware: I don't know, but NoR seemed to recognize them
Saul Goodman: TLDR, after Justin, Rick Astley, and a whole bunch of others broke out of The Wall, Gru knew he needed and actual attorney instead of posing as one... He tried to fire a mind control chip at him but 1) Gru missed, and 2) Saul wanted to help Wheatley anyway
Alfred Milano: Canonically, I haven't made that one clear... but c'mon! He's a disgusting little shit boy (Like, legitimately... People cheered when he died in the movie)
