The ponies ponder on what they may have done...
Under their glassy-eyed, fuzzy, adorable cuteness, they have the ability to KILL!
I would like to clear a few things up for the commenters.
- I read the comic where Chrysalis comes back. I own the book. Stop telling me that Chrysalis comes back, because I KNOW! XD
- No, Sombra was not "a lifeless cloud of gas, so he was never alive to begin with." Seriously, come on. He wasn't a "cloud monster" either.
- Yes, I know about the horn fragment thing. I've known since forever. Whether or not it actually MEANS anything is up to the writers of the show.
- When Twilight and Fluttershy say "we," they refer to all of their friends who faced Sombra's wrath. This includes Spike, Cadance, Shining Armor, their use of the Crystal Heart, and all that entails.
- Is Sombra dead? Is he still alive? Will he come back? Until the writers make these decisions once and for all, ALL of our theories are wrong.
