In the last episode of The Flash, we get to see Barry Allen travel back in time at the end, and Harrison Wells revealing his true name and nature. We understand that he is Eobard Thawne and that he has been trapped in the past for 15 years.
After returning back in time with future Barry Allen, Thawne's main objective was to kill Barry from when he was a young boy, but he ended up accidentally killing his mother instead. However, for some reason, Thawne became trapped in the past, and thus, he must help Barry become faster because it's the only way for him to go back to his world, his time.
Now, Thawne revealed all of this to Cisco before killing him, though he didn't want to. What's interesting is the fact that Thawne used the word, "world" instead of just "time." This makes us wonder if this Reverse Flash is from a different world because from our understanding, a person going into the future in the DC Universe doesn't mean they have entered a different world, just a different time in the same world.
We should point out that Grant Gustin, the actor who plays the Flash, claims there is another big twist to the Reverse Flash, and we're wondering if this is it.
If our theory of Eobard Thawne's ability to travel to different worlds holds true, then it could mean that chances are the Reverse Flash is from a world, and it could also mean The Flash could bring into play the Multiverse of different worlds. If such is the case, fans could be in for a treat because Warner Bros. and DC could easily claim that the movie and TV universes are separate but under the same multiverse.
Should this be done, it is very possible for fans to see some villains or heroes from the movie universe making an appearance in the TV universe or vice-versa.
At the end of the day, we could be putting too much thought into what Eobard Thawne said to Cisco. Still, going this route would be a great move by Warner Bros. to flesh out the DC Cinematic Multiverse once and for all.
