In season 2 of The Flash, we were introduced to the fourth version of the character: Harrison Wells from Earth-2, who comes to Barry’s Earth to help him stop the evil speedster, Zoom.
In season 1, Harrison Wells actually turned out to be the Flash villain Eobard Thawne in disguise.
If there’s one actor on The CW who has been given the opportunity to portray a range of characters, it’s Tom Cavanagh of The Flash.
However, based on a new report it appears that we are going to see Earth-2 Harrison Wells again in season 3 after all.
