Al is not a troll.
Albion is a man who cares very deeply about narrative flow and believes it to be genuinely for the better if Pyrrha were to stay dead, based on how she died and how the story has progress since her dead. Being a writer means being passionate about writing and story structure.
Albion is also a man who's been through the "she dead" discussion about 12 million times and is probably pretty sick of it by now, two years after she bit it.
It's the same for me on both counts, honestly. I'm just too ill to write up another permutation of my own "she dead" mega-essay. (Also, the more I engage in Pyrrhacourse, the less I actively enjoy thinking about Pyrrha, which is a shame because her entire arc through Volume 3 -- including her death -- was my favorite thing about the Beacon arc, and I'd love to do a really thorough breakdown of it sometime.)
TL;DR Al's not a troll, he's just a bit caustic about the whole topic because it's been a bit of a thing around these forums. Chill.
