Gale has not been in my party yet in this playthrough, but he is waiting at camp.
He hasn't told my character about his condition yet, but after a couple of long rests, he had an exclamation mark, and out of the blue, he told my character that he is in dire need of magic to consume, and asked her for a magic artefact (I had the Sword of Justice in my inventory).
The initial dialogue, where he explains his situation, was entirely missing for me.
(It reinforced my sorcerer's suspicion that wizards are weird 😄)
