Central City will play host to the Green Arrow and Vandal Savage as The Flash takes on season 2.

'The Flash' Season 2 Premiere: Who Really Saved Central City? Shocking Twist Teased

Photos from The Flash's Grant Gustin (Barry) and Arrow's Stephen Amell (Oliver) have sparked a flurry of crossover rumors, but it was initially unclear whether or not the gimlet-eyed hero was swinging into Central City or if Barry Allen was whizzing by Starling City. Tweets from Amell and Legends of Tomorrow's Casper Crump (Vandal), however, appear to hint at the former.

Check out Amell's Jitters tease, an ominous photo of Oliver and Barry (are they at a funeral?), and Crump's confirmation that he is working on The Flash with Amell and Gustin:

Will The STAR Labs team need the Arrow to help battle Savage, or will Oliver Queen stop by for an entirely different reason. Only time will tell. It is currently unknown which episode will play host to the Arrow & Legends of Tomorrow stars.

The Flash will return to The CW on Oct. 6 at 8 p.m. ET with "The Man Who Saved Central City." Following the events of "Fast Enough," the premiere will explain how Allen and Co. managed to shut down the Singularity before Central City became a heap of rubble.
