Barry Tells Cisco & Caitlin Harrison Wells' Secret On 'The Flash,' But He May Need To Do Some More Convincing

It seems like forever that they've been in the dark, but but Barry finally told Cisco and Caitlin that he thinks Harrison Wells is Reverse-Flash on The Flash, and now it's all a matter of whether or not they'll believe him. For the longest time in Tuesday's episode, he wrestled with whether he should even tell them in the first place. After all, as Barry pointed out to the visiting Felicity Smoak, Harrison wasn't just their boss, but also their mentor. There was always the chance that they were working in cahoots with him, and even if they weren't, there was a very strong chance that they wouldn't believe Barry and end up ratting him out to Harrison.

Despite his misgivings, though, Barry decided to trust his two friends by revealing his suspicions to them. Right off the bat, it was clear that Caitlin wasn't willing to buy it, but Cisco was ready to believe him right away. For some reason he seems to be having flashbacks to the altered timeline, where he saw Harrison Wells as Reverse-Flash just before the man killed him. Although we don't really have too much insight as to why Cisco is all of a sudden having these flashbacks (or why he has the worst luck staying alive in these past few episodes), whatever he remembers might be the key to finding Harrison out.

As for whether or not they'll win over Caitlin, it's still pretty unsure. We saw in the preview of next week's episode that she needs proof before she'll believe anything, because of course, from her perspective, she's never seen Harrison do anything too shady. Then again, in the alternate timeline where Cisco was killed, she was totally willing to cover for him while he was sniffing out S.T.A.R. Labs. I have to believe that her loyalties lie with Cisco before they do with Harrison Wells. The real question, then, is whether or not these three can uncover the truth about Harrison before somebody gets hurt — again.
