'The Flash' Season 6 Episode 14: After Pariah and Nash Wells, Tom Cavanagh returns to the role of Reverse-Flash
Reverse-Flash (Tom Cavanagh) is that insidious villain fans love to hate. Well now, in an already tightly-packed season filled with villains and open-ended plotlines, the Reverse-Flash has returned, and he is worse than ever. And this time, though he has taken the body of Nash Wells, he promises to slit Barry's throat...what a sweet homecoming.
Throughout the series, Eobard Thawne has to find a tiny loophole to get back into the folds of the main story, even when he has been killed or erased out of existence. And this might just be his most intense and frightening return to the series. Ever since the beginning of the series, the Harrisons of other worlds have become a permanent fixture in the Arrowverse storylines and viewers are now familiar with the numerous portrayals of the Wellses, played by Tom Cavanagh.
Just after the 'Crisis', Nash Wells kept seeing hallucinations of himself. One of them being the Sherloquian vision, which was the strongest foreshadowing of the Reverse-Flash. In the episode, titled 'Death Of The Speed Force', Eobard's energy appears to have attacked Nash's body and taken over, albeit without the powers. While being locked up in the pipeline, Thawne reminds Barry that he wants to kill him as well as everyone he loves. He assures that he will get out and his first target will be Nash.
In Season 6, Tom Cavanagh has essayed more than one role, apart from Nash Wells, the arrogant Indiana Jones-like traveler. However, it was Nash, who mistakenly unleashed the wave of anti-matter, therefore summoning the Crisis. He became Pariah, during the 'Crisis On Infinite Earths'. It was also Pariah who managed to transport the Paragons to the Vanishing Point, so that they could avoid being obliterated by the Anti-Monitor. He returned to being Nash Wells after the Earth was 'rebirthed', much to Cisco's annoyance. Cisco still held Nash responsible for the Crisis.
Cavanagh has tapped into the various personalities of the numerous Wellses and characters that he has played, and it's no surprise that he is a fan-favorite. From being over-confident to murderous, Cavanagh has shown his versatility.
'The Flash' airs on Tuesdays at 9 pm on The CW.
