Did You Know?


This is the third crossover with Arrow (2012) since Arrow: The Brave and the Bold (2014). See more »


When Barry is fighting "Everyman" in the airport storage area. The stuntman's costume is obviously loose and ill-fitting. The cowl is loose in the back and the stunt person is a bit shorter than Grant. See more »


Cecile Horton: You know, I saw The Flash once.
Barry Allen: Oh, yeah?
Cecile Horton: Yeah. I was on my way into the courthouse. He blew past me. It was... it was just a blur of red and gust of wind, but it was pretty damn cool.

What Proof?
22 April 2015 | by ThomasDrufkeSee all my reviews

I feel like there have been several episodes this season that I crown as my favorite so far, but perhaps "Who is Harrison Wells?" is the perfect mix of pure fun and just a well directed episode. I think I may have to go back and watch the series over again to identify which one is my absolute favorite but if anything else, this episode gave us everything we could have possibly wanted in one short 42 minute story.

We knew the episode contained the detective bro crossover with Arrow, but we didn't know that Coast City would make an appearance! Apparently Hal Jordan and crew enjoy the best pizza around. But the actual crossover was really fun even though Arrow's best characters didn't make an appearance. Laurel was bearable and actually quite likable. Lance is always interesting to watch and I think Joe was the right guy to come in and tell him he needs to fix his relationship with Laurel. I think we are all tired of the soap opera like Lance days. I thought I would hate the idea of Laurel getting the 'Canary Cry' but once again the writers made it work within the universe. Meanwhile Cisco's geek out over the Canary was priceless and I almost saw a spark between him and Laurel there.

Another spark came from Caitlin and Barry this week, or I guess just Caitlin. Going all the way back to 'Crazy For You', Barry & Caitlin have seemed like a better on screen couple than Barry & Iris. I have always been a fan of Panabaker's performance on the show and tonight was another great example. Caitlin struggled with the teams' new plan against Wells, or rather opinions, because they have no idea what to do. She served as the audience's feelings this entire year. We have been wondering how much of these good deeds and feelings are legitimate and genuine. But if we're talking about this week alone, I really liked the 'Everyman' storyline. Sure, it was a villain of the week episode, but yet the mystique like powers fit well in with this week. Meanwhile Joe and Cisco went to Starling and investigated Wells' crime scene. It was pretty convenient, but like I said before it worked well. I have to say though, I really thought Wells was somehow going to kill Joe in that last scene. It seems likely that one of Barry's fathers will die this season and I really hope it's not Joe.

In the Flash style after credits (not-so-after-credits) we saw the crew find Wells' lair if you will. Once again it's not anything we haven't seen, but it was nice to see Barry find out more about Wells and the possible disappearance of himself in 2024. I think we would all be terrified to see that in print about ourselves. So even though Starling city seemed quite different than how it usually is on Wednesday nights, I think the crossover was as useful as it was fun. We are definitely headed for an insane final 4 episodes.

+Light Starling

+Cisco geeking out

+Panabaker's hidden feelings

+Everyman was different

+Detective bros
