"The Flash" season 1 ended with Harrison Wells/ Eobard Thawne (Tom Cavanagh) getting wiped out from existence when his ancestor Eddie Thawne (Rick Cosnett) shot himself, altering the future. However, a report from TVLine now confirms that Wells will return in season 2 although he won't be the same person audiences met in season 1. 

"We've got other worlds. We've got other timelines. All I'm going to say is he's from one of those places," explained executive producer Gabrielle Stanton. 

This means that the Harrison Wells in season 2 might be the real Harrison Wells, a benevolent scientist who developed the particle collider. 

In season 1, the real Wells was killed by a time-traveling Eobard Thawne. Thawne then used his technology to make himself look like Wells and this was the person Barry Allen (Grant Gustin) and friends got to know. It is possible that a new timeline may have been created where the real Wells was never killed to begin with, and he may be the Wells that will be introduced in season 2.

Having a benevolent Wells will serve as a means of retaining the balance seen in season 1 amongst the main heroes. Although a villain, Wells in season 1 had a way of leading the team, so it will be interesting to see how different the "real" Wells will be compared to the Eobard Thawne version. 

However, just because Thawne is gone and the real Wells will be there to guide Barry and the team doesn't mean that there won't be a speedy villain to challenge the Flash in season 2. As reported by ComicBookMovie, Professor Zoom will be the next season's villain but his ties to Thawne are unknown at this point.

Confusing timelines and alternate realities are commonplace in the "Flash" comic books and it appears that the TV series will follow suit. These will unfold when "The Flash" season 2 airs beginning Oct. 6.
