Dylan O'Brien Must Choose A Side In This Exclusive Clip From 'Maze Runner: The Scorch Trials'

WCKD or nah?

When Thomas (Dylan O'Brien), Newt (Thomas Brodie-Sangster) and the rest of the Gladers exited the titular maze in 2014's "The Maze Runner," they probably thought they were in the clear. But as Thomas quickly learns in the film's upcoming sequel, "The Scorch Trials," the world outside the maze isn't all it's cracked up to be -- in fact, it's populated by the likes of Littlefinger from "Game of Thrones."

In this exclusive clip from "Maze Runner: The Scorch Trials," Thomas is confronted by Littlefinger Janson (Aidan Gillen), who asks him the most important question of all: whose side are you on?

Only time will tell which side Thomas chooses, so all we know is that we're on the side of "please let it be September, so we can see this movie ASAP."

"Maze Runner: The Scorch Trials" hits theaters on September 18.
