Did You Know?


Grant Gustin (Barry Allen/The Flash), Carlos Valdes (Cisco Ramon/Vibe) and Melissa Benoist (Kara Danvers/Supergirl) are the first actors to appear on all four of The CW's DC shows: Arrow (2012), The Flash (2014), Supergirl (2015) and DC's Legends of Tomorrow (2016). See more »


When Barry introduces Supergirl and she levitates to prove her alien nature, she also uses her heat vision to burn her family crest into the floor behind the rest of the team. No one looks at what she's doing, only looking at her, which they should as, from their positions, her heat vision would have had to cut through Professor Stein. The heat-vision effect was added in post and not originally scripted. Later in story-time, Barry has to explain Kara's heat vision to Oliver quickly in battle, which he should know from the aforementioned introduction. Complicated by that explanation being depicted twice. See more »

Green Arrow: Oh, wow! You really did it this time, Barry.
The Flash: Seriously?
Green Arrow: Yeah, yeah. Yeah, seriously! You to come to Star City, ask for my help, and then, inevitably, immediately, we end up the creek!

Wait what??
14 February 2019 | by stejlhaveSee all my reviews

I created an account after this episode (and yes I know I'm late, but read it to know why).

I am binge watching The Flash on Netflix right now.. I have watched Arrow but because of Netflix I am not caught up.

I live in Europe and depend on Netflix when I watch my shows, buuut Netflix does not have every show and the once they have are not all caught up exept Legends Of Tomorow wich I don't watch because I don't want spoilers from Arrow and Flash (love both shows).

I tried a few (maybe 5) episodes of Supergirl, but that show is not for me... but with this episode of Flash i feel that the creators are trying to force me to watch the other shows.. witch even if I wanted to, I can't cause I don't live in America...

I love cross overs I really do, but like this... to continue it in a whole other show and then another... nope..

So I have to rate this much lower that I would have, if it had an ending or the next episode was on The Flash..
