Okay but what about the rest of Mane Six and Spike in "Princess of Monsters" AU? What was their thought process on stuff what Twiligh pulled?
The whole premise of Princess of Monsters is that Twilight only started her "road of evil" after her friends passed away, so the Mane Five (and by extension, some familiar characters like Shining Armor, Starlight, Sunburst and even Trixie are gone as well).
The "issue" with Spike is that he actually does show up alive in G5 (I still need to WATCH THAT tbh), so I need to find a way to link up G4 Dragons to G5 Dragons, and I'm still brainstorming ideas for it tbh hahahe.
I do like the idea of G5 dragonfire being magic, so I'm going to say that for this particular AU, dragons could ALWAYS do magic with their fire, even G4 ones. Ponies just didn't know that because dragons were understudied.
Overall I'd say Spike was alright, if skeptical, of the path Twilight was choosing for herself. When she started studying dark magic, he was skeptical, but didn't speak out because it's not like she was planning to USE it for evil, only for research, and besides... It was the first thing that made her excited after everypony's passing... so he let it slide. And then the Villain Redemption Project came and the same thing happened, then she and Tirek became a thing and the same thing happened...
Things only got particularly bad during Opaline's rising... Again, I'm still brainstorming. Haha.
