I had an interesting discussion with friends and there are some more things, that I think, Wyll is missing.
A lot of characters have trauma due to not being free , yet here is Wyll, still literally being a slave to Mizora and he gets not much to say. Same with his physical changes - he did literally suffer through all torments of hell, which I doubt even Abdirak would find amusing, and his whole body gets changed in the process and he doesn't get a scene around it, just a bit of dialogue, which mostly makes fun of it. Menawhile we have a whole scene with Astarion over his looks and Shadowheart over a changed hair colour. And before those two fangroups jump at me: I don't want to say, take that away, I just think, it's sad, that we literally see, what a companion goes through and there is not a similar moving scene for him afterwards. I know Wyll is the stoic type and shrugs a lot of stuff away, but I think, he just had the worst day imaginable and should have had more than a short comment afterwards. What he experienced, should traumatize everyone.
I just put it out here in case, there is the slightest of chances, there might be something to be done about it.
