Thanks to a mishap with attempting to power the Artificial Speed Force with the multiversal particles contained within Nash Wells, all of the Harrison Wells personalities that had been languishing inside Nash post-“Crisis on Infinite Earths” ended up inside Barry Allen, resulting in series star Grant Gustin imitating a handful of the Wells characters that Tom Cavanagh plays.
Perhaps understandably, Gustin was concerned about delivering these strange performances.
The Flash has delivered a lot of craziness to viewers over the years, but the Season 7 premiere, “All’s Wells That Ends Well,” brought one of the show’s weirdest moments yet.
