One thing that doesn't make sense to me is how Wyll keeps calling himself a hero and can agree to bind himself to Maryzora forever for his father to be spared (who is just a single dude who doesn't even appreciate him), yet at the end when a hero is actually needed to save the ENTIRE WORLD he doesn't step up and offer himself. Why is that? I wonder.
For the same reason why Lae'zel doesn't offer herself instead of Orpheus (if you side with him), even though she spent the entire playthrough lecturing my character how important he is. Or why Gale doesn't offer, even though he is ready to detonate the orb. Tbh, my impression was that they only made Karlach do it, so they could have this ''surprise! her condition can be cured!" plot twist.
Gale actually does say "There is still my option with the orb!" but the game does not allow you to act on it unless you play as Gale. You are still supposed to turn someone into a mind flayer.
That it incorrect (again, unless they changed the way the dialogue works in patch 5, since I haven't completed a playthrough with that patch). You can side with Orpheus and avoid turning anyone into mindflayer, if you have Gale in the party (and have him detonate the orb). But the dialogue to achieve that is conplicated. Storywise it makes no sense, it is just done this way to prevent the player to be able to turn two characters into mindflayers (Karlach & protagonist). So it would not surprise me if most players won't find that option.
