[Warning: Potential Spoilers for the latest episode of The Flash lie ahead. Proceed at your own risk.]
Okay. So today's episode was the usual fun with a metahuman coming to 'kill' The Flash because Zoom sent him and promised to take him home on succeeding. But before I get to the Zoom-y stuff, here's what all happened in today's episode.
1) Caitlin grieves Jay Garrick's death.
Throughout the episode, we can see that Jay's death had hit Caitlin hard. She suddenly wasn't the normal Caitlin anymore, she appeared as a cold person. When Cisco asked her why she was behaving like this, she said "Because if I let my self feel, then if I let out all my pain and anger, it's never going to stop." But at the end, we see Caitlin become back to her usual self again.
2) There's no way back to Earth-2.
In the episode, we see that Barry wants to go back and face Zoom. He wants to go back to Earth-2 and avenge Jay's death. He feels that he just ran away from Zoom to escape him and that he left a whole world at Zoom's mercy, so he tries to find a way to get to Earth-2 again.
3) Barry and Wally try to bond.
In the episode, we see that Barry and Wally try to bond over his engineering project. At first, Barry is hesitant because he thinks Wally has a problem with him, but then he helps him anyway. Wally acts like a dick around Barry when Barry helps him out in his engineering project, saying that he "doesn't need his help."
4) Harry and Jesse have quality father-daughter time.
Harry and Jesse bond over the problem that King Shark is in Central City and they have to track him down. Jesse asks Harry if she can help him and he's hesitant. She goes on to say " You wanted me out of that room, and now that I am, you don't want me here. Just let me help. Please." Harry agrees and tells her to "grab a marker."
And now, for the moment we've all been waiting for...
5) Zoom's identity revealed.
OMG YAS. We finally learn that Zoom is, infact, Teddy Sears. And I say he's Teddy Sears because it's not entirely clear if he's playing the role of Jay Garrick, Hunter Zolomon, or someone else entirely. We also get a look at the Man In The Iron Mask, who is extremely shocked at the sight of "Jay Garrick's" dead body. The episode ends with Zoom revealing that he's Teddy Sears while saying "Well, this..... is a complication."
