Nanamo bothers because, well, yeah, everyone has gone over it. That was absolutely not just taking some sleeping medicine, and going back on it felt cheap after the drama of 2.55. Zenos because so far he hasn't even done anything, so it makes me question why bring him back at all. And Yotsuyu because her arc is why I'm not a fan of Stormblood's MSQ, with Square spending so much time and trying so hard to make me feel sorry for a complete monster of a person.

With Louisoix and Gaius, they don't bother me because we never actually saw them die.
