Did You Know?


Barry's HUD display is brought up by lenses that go on his eyes. In the comics, when Wally was the Flash, he also had lenses similar to this. However they were white. See more »


When the remains of Tim Kwon's car slides up to the barrier, one of the tires hits the barrier a couple of seconds later. When it does, the barrier bounces away and then back. This barrier would be either a concrete Jersey barrier or the portable plastic Jersey barriers which are filled with water once in place. Neither would move and rock from the light impact of a rolling tire as they are too heavy and designed to stop or deflect a car, which is about 30 times the weight of the tire and wheel, so this is either a prop "concrete" barrier or a plastic one that was not filled with water.

Iris West: You need to throw a lightning bolt.
The Flash: At what?
Iris West: Yourself.
Joe West: You want him to do what?
Iris West: It might short the suit out, give him back control.
Cisco Ramon: Or it might set off the self-destruct early.
Caitlin Snow: Or it might stop his heart.
Iris West: Barry... Barry, you need to listen to me, okay? We can do this.
The Flash: Okay. No, I trust you, Iris.
Iris West: Then run, Barry. Run.

Who is that new guy?
18 October 2017 | by gorkem-birSee all my reviews

Barry has dealt with a lot in the previous season. He had gone through so much and felt desperate and exhausted most of the time. And now, he suddenly came out of speed-force like nothing has happened. He is joyful more than ever, and it is not because that he is grateful to return to the world or Iris. It is something extreme. His attitudes, behaviours are so incongruent with the stereotype that I could recall. I've even thought about the possibility of our new villain to shape and control the actions of him. Iris seemed to suspect that he is not the fiancée who went into the speed-force couple months ago. I don't know whether anyone else have noticed that, but it is a disturbing issue unless it is something fictionalized. Besides, add something new. I don't want Barry to gain his confidence following an emotional talk anymore.
