[This post contains SPOILERS for season 1 of The Flash.]
Last season on The Flash, Barry Allen fulfilled his lifelong mission of confronting the man in the yellow suit - only to find out that it was fact his mentor, Harrison Wells (Tom Cavanagh). Well, it was Eobard Thawne disguised as Harrison Wells, but you get the idea.
Wells proved to be one of the show's most intriguing characters, but with the death of the man posing as him, it seemed like that would be the last we would see of the genius scientist. A new interview with an executive producer on the series, suggests that may not necessarily be the case.
According to TVLine, the return of Wells is not just a possibility; it's a guarantee. When questioned about whether or not The Flash will bring Dr. Wells back into the fold, executive producer Gabrielle Stanton had this to say:
"Harrison Wells will be back, but he's going to be a very different Harrison Wells than we've seen before... We've got other worlds. We've got other timelines. All I'm going to say is he's from one of those places."
Obviously, the return of Wells could come via a few different scenarios. The element of time travel means no character can ever be taken completely off the table - Barry even managed to briefly reunite with his long-deceased mother during the season 1 finale. Stanton's mention of "other worlds" likely indicates that the Wells viewers see next will hail from another universe in which Eobard Thawne never tore his life apart, and perhaps even one where Jay Garrick became the Flash instead of Barry Allen. As an entirely different person, this new Wells may respond to our hero and his set of circumstances in an entirely different manner. And a scenario such as that could create a character wholly different from what Cavanagh has already brought to the table.
Introducing the multi-verse is a big step for The CW's DC properties. While it obviously opens up new possibilities for complex storytelling, it also provides new ways to introduce outlandish concepts to the universe in question, as well as alleviate the permanency of death on their shows - although characters on The Flash and Arrow already have a somewhat tenuous relationship with death as it is.
We won't know for sure how Harrison Wells makes his way back to Central City in season 2 of The Flash, but we will begin to find out when the show returns in the fall.
Season 2 of The Flash premieres Tuesday, October 6 at 8pm/7 central; Season 4 of Arrow debuts Wednesday October 7 at 8pm/7 central; Legends of Tomorrow begins in 2016.
