The Mysterious Informant

Trixie from the Changeling Takeover Timeline wasn't the only pony to sneak through that portal and end up in Cloudsdale, seven years ago. This Twilight might be older, jaded, cynical, violent, trained by an evil queen, and hopelessly devoted to Nightmare Moon, but it's a universal constant that Twilight will always be a total pig who loves burgers and junk food :P
