Okay so, I like making solo characters. Some of them are nice and don't do mean stuff to Gale, but instead rebuff his offer to join the party, leaving him to stand by the Cliffside portal forever.
However, after progressing to a certain point, you can go back and he'll have a conversation bubble floating over his head, and if you talk to him he'll launch into his usual dialogue re: his 'condition', speaking as if you've been travelling together the whole time.
It makes sense that he would still need to treat his condition at this point, but the dialogue isn't correct for the circumstances.
SUGGESTION: Have Gale's NPC travel to the Grove after being told to shove off, and assign him new / correct lines.
