5. The Arkham Knight Knows Scarecrow's Plan
Shown walking alongside the hooded ghoul himself, the aforementioned "meeting" that started everything off has somehow left the Knight siding with Scarecrow - something that can't be said for the rest of Gotham, as the other villains are scattered asunder, Ivy is even the one filling in Batman on what's happening for an as-yet unknown reason. There's plenty of narration from Ivy throughout, but when voice duties switch to Scarecrow addressing the city and its inhabitants, everything is then shot to at suggest that each party brokering the initial deal is ready to stab the other in the back at a moment's notice. Penguin in particular looks furious, and taking into account what's obvious from the comic, having the Knight so far up the chain and in leagues with Scarecrow can only end badly once his true intentions become known. Where beforehand we were uncertain if the AK was a wholly separate entity, it's now confirmed both through the comic and this new trailer that he's (at least on face value) in league with the bad guys at the beginning of the game - just don't expect it to last long.
