5 Predictions For The Flash Season Finale

The CW's The Flash has left a lot of big ideas on the table and a lot of mysteries unanswered going into the Season One finale on Tuesday.

And with the main villain of the series seemingly defeated and an episode left to go, one has to assume there's at least a couple of big twists and turns coming up.

So...what's up for Team Flash and company? Here are some of our best guesses.

Something big happens to Ronnie Raymond

We already know that Ronnie and Caitlin get married, as we've seen in a trailer. So...where is Ronnie when it comes to DC's Legends of Tomorrow?

Foregoing the obvious "he's at home, washing his tights" answer, it's worth noting that not only did we not really get a good look at Ronnie in the promo spot for Legends, but his name hasn't been officially mentioned in connection with the show at all, prompting some (including this reporter) to speculate that Professor Stein could have a different partner in the Firestorm matrix come time for the series to start.

Introducing...the multiverse?

That shot a fan noticed with the helmet of Jay Garrick, the Earth-2/Golden Age Flash? Well, it happened during a sequence where Harrison Wells was in a Time Sphere, with a dimensional vortex of some kind in front of him.

We see that same sequence (or one just like it) in the comic made to promote the season finale.

Prior to the Crisis on Infinite Earths, Garrick and the other Golden Age heroes were shunted off to Earth-2, so that their histories could remain intact but they could make way for younger versions to be the "main" heroes of the DC Universe. Following the events of Crisis, that alternate earth was one of the ones rolled into the main DC timeline, meaing that the heroes shared a single world and continuity, but that the Earth-2 heroes' adventures had happened primarily in the '40s and '50s, whereas the younger generation of heroes first apppeared in the early '80s.

There had been a previous Jay Garrick Easter egg -- "Garrick's Wharf" was a location in Keystone City when the Central City PD visited there -- but there has been no reference to a previous Flash. Since the Crisis hasn't happened yet on The Flash, it's likely safe to assume that this indicates that Wells is traveling through the multiverse. So...will we actually be TOLD there's a multiverse on Tuesday?

And of course, if they do introduce the multiverse, does that imply right away that one of the worlds of the multiverse is the DC movie universe?

The cosmic treadmill

If Barry is going to travel back in time, he's going to need something that will help him build up sufficient speed to do so without causing potential harm to, or being seen by, the general public.

So...enter that treadmill that's been sitting around S.T.A.R. Labs since the start of the series. Considering that The Flash uses "The Cosmic Treadmill" to travel through time in the comics, it's hard to imagine that Wells didn't have plans for the item that's been sitting in his lab all along, at some point.

Above, you can see the Cosmic Treadmill in a bit of a timestream fender bender with Rip Hunter and his Time Sphere. Don't worry; it wasn't Barry's fault. Booster Gold was driving the time machine while intoxicated.

Flashpoint

To some extent or another, it seems inevtable that we'll get are the long that the show will explore the idea of Flashpoint this year.

The world of Flashpoint in the comics was created when Barry Allen traveled back in time to stop Eobard Thawne from murdering Nora Allen. He succeeded, but it radically altered the timeline, and when he returned to the present, it was one where he didn't have powers ad the world was on the bring of a catastrophic war. 

Given that the trailer for the finale shows Barry successfully going back in time to save his mom...!

At least one more major Wells double-cross

Whatever happens in the past, and whatever its impact on the present and future, you can bet it's something that Eobard Thawne has planned out.

We see a lot of him gloating in trailers, a lot of "I always win" and what appears to be a post-time-travel realization on the part of Team Flash that they've made a huge mistake. We also know that, one way or another, Wells gets his hands on a Time Sphere.

So what does all this mean? It's hard to say at this point...but
