Ascension
I adored this quest so much. Sunday is a fascinating character and the way the story represented his viewpoint was in my opinion very well made. The scene where he talked about the letter Robin gave him and what the dream master told him gave me chills.
Just as a character I think it's very easy to resonate with him simply on the basis of his fears. Sunday cares so much about everyone he meets, he's a bleeding heart and he already feels like he can't truly help people or at least keep them safe.
So his desperate clinging to control makes sense but then the scene with the letter just him realizing that no matter what he does the most important person in his life puts herself in danger all the time and he can do nothing at all he may not even know if she's hurt. like this and all the other things we get to see about him makes him just an amazing character
