'The Flash' Season 2 Episode 1 Air Date: 5 Biggest Plot Spoilers to Watch For

If you were surprised at "The Flash" season finale, you are not alone. Spoiler Alert: Eddie's and Dr. Wells's (well, Eobard's) deaths came out of the blue but with a black hole eating up Central City and (potentially) the rest of the world, it seems that The Flash needs more than the Arrow to help save mankind.

Unfortunately for fans, no details were revealed on how they're going to save it. However, their success appears to be certain as the world is intact in the "Legends of Tomorrow" trailer.

Here are some spoilers about the next season:

1) Comic Book noted that at some point, Barry will be on the other side of the prison cell, as seen in one of his visions during while he was in the Speed Force. Barry in prison? How did that happen? Is it set in the future or in an alternate universe somehow?

2) Jay Garrick's helmet made an appearance in the last episode, which signaled Reverse Flash/ Harrison Wells/ Eobard Thawne that he needed to get out of his current timeline. Is there a possibility that another Flash will show up next season? Some fans surely hope so.

3) Cisco is Metahuman. Well, he's not sure about it yet, but Harrison Wells/ Eobard Thawne appears to be certain about it. Although it hasn't been confirmed yet, many think he's going to appear as Vibe next season, according to Inquistr. What's more awesome than Cisco? Cisco with powers, that's who.

4) Grant Gustin (Barry) revealed to Movie Web that the next season will explore multiple timelines.  He said, "What's fun about this show is that there's going to be multiple timelines as we move forward. I think we're going to start showing Earth-One and Earth-Two in the near future. There will be kind of different dimensions going on."

5) Reverse Flash is still set to appear next season, which means that there's more to Tom Cavanaugh's role. How he will be back, however, is the question, considering that Eddie, his great-great-ancestor and Iris' boyfriend, put a bullet through his heart to ensure that the Thawne line spawning the evil Eobard dies with him.

What do you think will happen on Season 2? Are you excited to see what's next for Barry and the rest of the team from STAR Labs?
