In my headcannon, they meet a parallel Twylight who’s as this. How? A fusion of the Marer Do Well and Walking Dead hoaxes; only the CMC And Deroy squeal. And the deformity was cause by chemicals when she attacks to shut them to I oh for our rainbow-head pony to save them and cause her to get her scars; karma for her sins. And based on a scene from Batman: Arkham Shadow, some ask the rainbow pony if she’s alright to which Twylight repeats in anger; her jealousy and anger coming out. The Two-Face of Equestria.
