* How the heck is Avenger so clued-in on ''Anime/NeonGenesisEvangelion'' and ''Anime/TengenToppaGurrenLagann''? Shirou in VisualNovel/FateStayNight didn't exactly live in front of a TV even before his life took a turn for the strange, and it's not like he can look them up now that he's incarnated in ''FanFic/FateZeroSense'' since those shows never existed in that world because A) the creators made ''Neo'' with James Cameron instead and B) neither ''Anime/RebuildOfEvangelion'' nor ''Anime/TengenToppaGurrenLagann'' would come out for at least a couple years.
** Easy: in the future ''he'' comes from, they're extremely popular anime series he watched at least once in passing, and his memory is just that good.
