Seasonal death counter:3 (+0, This really is a good time to add to this counter, Subaru. Things are already looking pretty grim as they are, you don't want that save point moving now!)
So the archbishop wasn't actually a dragon (even though they have the blood of one), they were a damned shapeshifter! Anyone who had to deal with Orin and her gang of shape-changing murderers in BG3 knows how annoying those things can get.
Capella really asking the "Would you still love me if I was a worm?" question except literally.
Regulus is pretty interesting, he's relatively "sane" compared to the rest of the bunch, he's just an absolutely awful egoistical asshole who was given demigod level of power so no one can say "no" to him. It really makes his just so very hateable even when compared to the rest of his already hard to like comrades.
Yeah, I've wondered that too. He doesn't even really need a weapon either, just spill his secret and he gets an instant heart attack anyways. Unless I forgot some detail from Season 1 (I very well could, it has been a long while) there is no penalty for suicide over getting killed and with how gruesome most of his deaths are he really could use an easy way out.
