I like all the companions in their own way, but that doesn't stop me thinking that some of them are actual grade A morons (wyll and gale im looking at you)
What? Why them? Those are the most "sane" people there!! ^_^
Wyll is the literal Hero archetype and he shares my great hate for Goblins. =) Gale is not that much of a Hero, but he too enjoys doing good stuff. How are they moronic?
Wyll was seduced into selling his soul by a sexy cambion lady who promised him power. Gale implanted himself with a nuclear bomb because he was horny for a goddess.
