My biggest issue with Gale is that he costs loot to maintain so to speak. In early access I was lucky enough to have on hand items I wasn't going to use anyway, but I'm not sure if I'm willing to put up with it in the actual game. It might be better for me to simply not recruit him. But I'm also interested in seeing where his story goes and how we can affect it, so he'll probably get to come along. Undecided, but leaning in his favour.
I don't want to go into the spoilers, but you can keep him around even if you deny him the items.
