'The Flash' Season 6 Episode 13 hints at the much-awaited return of the sinister Reverse-Flash
'The Flash' aired a nice, fluffy little episode titled 'Grodd Friended Me', which introduced a post-Crisis reformed Grodd and revealed that Eva McCulloch is actually evil (no surprises there). Yet, none of these were half as interesting as Harrison Nash Wells's (Tom Cavanagh) storyline.
Throughout the episode, Wells was hallucinating and seeing visions of Sherloque. The episode ended on a cliffhanger, where Sherloque's eyes glowed red and he said, "He. Is Coming." Fans are certain that this scene heralds the return of the Reverse-Flash. It was assumed that he would return for the Crisis episodes, as his parting words to Barry Allen (Grant Gustin) at the end of the Season 5 finale were, "See you in the next crisis." However he did not and Tom Cavanagh played only Nash Wells, who later became Pariah. It's quite possible that 'The Flash' could be making up for the Reverse-Flash's absence by utilizing the several drastic changes in the post-Crisis Arrowverse.
A little refresher on the Reverse-Flash. Barry and his team have battled deadly villains over the course of six seasons, no doubt, but there is something quite sinister about the Reverse-Flash. He made his appearance in Season 1 itself after taking on the appearance of Harrison Wells. With the help of his power, he fiddled with the event that gave Barry his powers in the first place.
Reverse-Flash was even erased from existence, yet he somehow just kept coming back. At the end of Season 5, he manipulated Barry and Iris West-Allen's (Candice Patton) daughter Nora, into constructing a situation where he could escape from prison in the future. Since then, he hasn't made an appearance and the show was caught up in the deadly multiversal Crisis that shook the Arrowverse.
The next episode of 'The Flash' promises to be an exciting one as we see the return of Wally West. 'The Flash' airs on The CW on Tuesdays at 8 pm.
