The Flash is set to return to the airwaves for Season 4 next week, and we'll get to see how the characters picked up after the destructive conclusion of the Season 3 finale. The end of Season 3 saw the death of yet another version of Harrison Wells when Savitar killed H.R. of Earth-19, but Tom Cavanagh is on board to return in Season 4. So, naturally, fans have been wondering which version of Wells would appear in the new season and how the show would handle him. Executive producer Andrew Kreisberg has teased some of what we can expect out of Harrison Wells in Season 4, saying this:
We're picking up with Harry. We felt like we managed to pull off three different Wells in three years, and rather than just going and doing another Wells, we definitely felt there was more meat on the bone with Harry. Harry is a genius, and his daughter is safe, and she's The Flash on Earth-3, and he's one of those people who's realizing that he doesn't have a life. So season 4 for Harry is really realizing what he's missing in his life and what it is he needs to become a better, more complete person. So he's going to be going on a fairly epic emotional journey this season that is tied to The Thinker's plan, and we're really excited about it. It's probably something a little bit more emotional than we've ever done for that character, but Tom is such a phenomenal actor, we know he'll knock it out of the park. I'll also say that Harry won't be the only Wells we'll see this season.
We've known for a bit that Season 4 would feature Harry, a.k.a. the Harrison Wells of Earth-2. According to Andrew Kreisberg in his chat with EW, the crew at The Flash felt that there was a great deal of ground still to cover with the Earth-2 version of Harrison Wells. It sounds like the show will be able to tie his development to the actions of the new big bad of the year, and we'll get to see Harry get more emotional than we've seen in the past.
Given that Harry has been the quippiest and most caustic of the Wells that have been introduced on the show, an emotional journey -- perhaps not one connected to his daughter -- could be an awful lot of fun and show off a new side of Harrison Wells. That said, Andrew Kreisberg did tease the existence of at least one other Wells in the course of Season 4. The ability of speedsters to change time and cross between worlds mean that pretty much any version of Wells can theoretically pop up, including Earth-19 H.R. or perhaps even the dearly-departed Earth-1 Wells who had been replaced by Eobard Thawne.
Personally, I'm pretty excited to see more of Harry in Season 4. While there's a certain novelty in meeting different versions of Wells in different seasons, Harry's interactions with Team Flash were always entertaining, and he served a more direct purpose on the team than H.R. the novelist ever did. That said, it should be fun if we get to see versions of Harrison Wells from Earths other than -19 and -2. Tom Cavanagh has been able to tackle every version he's been asked to play so far.
We don't have too much longer to wait until he's back in action. Season 4 of The Flash will premiere on Tuesday, October 10 at 8 p.m. ET on The CW.
