The second season of “The Flash” was just wrapped up. Fans would now have to wait at least four months to find out what happens next. Where is the show’s next instalment headed after that momentous finale? Below, we round up five big spoilers and theories you should know ahead of the next season’s premiere.

1. Who might join DC’s favourite speedster next?

E! Online speculates that the events of the finale “opens the doors for many characters to join the show.” According to E!, some of the iconic characters that might drop in next season are Batman, Cyborg and Citizen Cold. The Joker,  the Furies, Heat Wave and Aquaman could also pop in, too.

2. Will he try to change everything back?   

In the finale, the Flash went back in time to save his mom Nora. In doing so, he altered the timeline and changed the history of his friends. Seeing the changes he caused, he might just try to change things back. However, this remains to be seen.

3. Will the unchanged timeline still exist next season?

A writer from Collider, Kayti Burt, hopes so. “Audiences are most likely going to get tired of an alternate timeline sooner rather than later,” Burt argued.

4. Has Barry Allen also changed the timeline of other DC shows?

Collider does not seem to think so. However, more crossovers might now be possible.

5. Will Jay Garrick stick around next season?

Season 2 revealed that The Man Behind The Iron Mask is the real Jay Garrick. John Wesley Shipp, the actor who plays Garrick, said producers still have “exciting” plans for his character. “I will be back next season,” he told Entertainment Weekly. “They have all kinds of exciting and interesting plans for me…they continue to spin out, which will be very challenging for me as an actor.”
