>Celestia is incapable of loving again
Damn, the Zulu fucked up her pussy that bad?
Seriously though, what's the context for that? It's not quite a complete enough statement for me to understand the meaning. Clearly she loves Twilight as a student, her land of Equestria, and her sister, but that's a different kind of love from romantic love, so what is it? If it's just that she can't romantically love again, that fits with the comic where she is romantically involved with a good mirror version of King Sombra who has to sacrifice himself, and it honestly doesn't clash with the canon of the early seasons seeing as it is an unexplored topic. If it's loving anything in any way period it's way out of character and I doubt Faust would have said that.
