Tom Cavanagh is best known for his portrayal of the different versions of Harrison Wells since “The Flash” series kicked off. With H.R. Wells dead, a new one is set to join Team Flash. However, it will be interesting to see what kind fans will see.

Wells started out as that evil speedster “Reverse Flash” and eventually transitioned to a comic novelist in H.R. Wells. While most saw him as indispensable due to his inability to aid Barry Allen (Grant Gustin) and the rest, he did make the ultimate sacrifice of taking Iris West (Candice Patton) in the season 3 finale.

The Wells from Earth 2 is around, though his stay is suspect. Obviously, he has his own Earth to manage so the search for a new guy is likely for season 4. The only question now is: Will he be witty, comical, or will he have evil intentions once more?

Cavanagh plays it safe

The best person who would know is the guy who has played all the Wells versions. Cavanagh was around during the Comic-Con in San Diego, with Cinema Blend fortunate enough to talk to him. As expected, he played it safe, though he hinted that there would be a new Harrison Wells next season.

“We're just gonna start there, with [Harry], and see as we progress toward the big season arcs -- I don't know what you guys know about the main villain and stuff -- but we're going to, around that time, see what other versions of Wells are available.”

Technically, plucking out another Wells from another earth does not make the eventual addition to Team Flash new.

It is likely that they will send off alerts (or job ads) for the role where someone with a new arc will be added to the team. Will it be another genius or someone who has other things in mind?

How about a Wells with mutant powers?

Fans have seen the many faces of Wells in the past though there is one that could happen. With no help coming from Cavanagh, how about adding someone with metahuman powers similar to Cisco (Carlos Valdes) or even Kaitlyn Snow/ Killer Frost (Danielle Panabaker)?

The best way to go about it is to skim the comic books for overlooked metahumans who could be inserted into the fray. Show-runners have marvelously found ways to re-educated the audience on heroes (and villains) so that could be a possible arc.

If not someone with special powers, fans could see a plain Harrison Wells with high IQ or someone pegged to give Team Flash more worries than help. “The Flash” returns on October 10 on the CW, where the more pressing matter is Barry returning from the "Speed Force" hole.
