What do you mena by alternate final p[arty, I played it way back when so maybe thsi is from the new version. you cna tag it as spoiler so TC does not see.
okay huge spoilers
Late in the game there is a snow village. Someone will knock on your door. If you choose not to answer them, a second person will knock, then a third. Refuse all 3 and you get an alternate final party.
honestly the normal final party is better imo. Its better that this character is a triple agent instead of a double agent. Only pretending to be evil fits their narrative better. Theres a lot of pain hidden behind the jokes. It makes sense for them to not be a traitor in the end.
