Tom Cavanagh has brought various versions of Harrison Wells to life throughout The Flash's run. And going into the show's fourth season, fans can expect an entirely new arc for one of Wells' dopplegangers.
"He’s a genius, and his daughter is safe, and she’s The Flash on Earth-2, and he’s one of those people who’s realizing that he doesn’t have a life."
In past seasons, Harry's arcs have been pretty much larger-than-life, with him teaming up with Season 2 big bad Zoom (Teddy Sears), and being captured in Gorilla City in Season 3. Kreisberg hinted that Harry's new storyline will involve the newest Big Bad, but in a new way.
"Season 4 for Harry," Kreisberg explained, "is really realizing what he’s missing in his life and what it is he needs to become a better, more complete person. And so he’s going to be going on a fairly epic emotional journey this season that is tied to The Thinker’s (Neil Sandilands) plan."
Harry might also encounter a new challenge as the season goes on, with The Flash expected to bring in yet another Wells doppleganger at some point. Fans will just have to wait and see how that unfolds when The Flash returns for its fourth season on the CW on Oct 10, 2017.
