Eobard plans on getting back everything that was taken from him.
Iris meets Barry at Jitters. She has 2000 return mailing labels when she only ordered 200. She misses Eddie and is upset they haven't found him yet.
Cisco calls and when they get to STAR Labs, he's been looking at the chair. In the chair is the the tachyon stuff. Wells was using the chair to power himself and that's why he's so much faster than Barry. The particle accelerator suddenly fires up. He's not only inside STAR Labs, but has rebuilt the accelerator.
Cisco takes his orange soda and they go after Eobard (still calling him Wells). Eobard has released the prisoners. Whoops.
Iris walked right into STAR Labs again, so NOW we have to assume she has a key.
Eddie is screaming help. He's a mess, but he's free and Iris is there to save him. She sticks around and looks for stuff instead of going with Eddie. She finds her engagement ring, closing the lid on it.
Eddie gets confirmation the name in his dream was real. Eobard Thawne.
Caitlin worries about the prisoners. If they are in the cells when the accelerator starts up, they die. Barry decides he'll call Oliver about Lian Yu. Joe doesn't like taking them from one bad place to another, but Barry doesn't think there is much of a choice in the matter.
Joe asks Singh's replacement to help clear a route. Cecile doesn't want to get involved and she just won't. She advises him to stay away from it.
Barry asks Captain Cold's help in moving the metahumans. After all, Cold loves the city and he wants to rob it for a long time. If they ruin it, he can't live there and continue to pillage.
Iris finds Eddie at work and doesn't understand why he's being so cold. Eddie tells her Eobard showed him the future and he's not in hers. She, however, marries Barry.
Joe thinks Barry is nuts for going to Cold. Seconds later he walks into the lab. Again, the place has absolutely no security.
Barry wants to save the metas because Eobard created them and doesn't care what happens to them. Barry does. So, Barry deletes all records everywhere of Cold.
Lisa Snart has a Class A CDL so she'll be driving the truck carrying the metas to the airport. Barry clears the way and everyone makes their way. The metas start waking up. Mardon wants to fight everyone with his bare fists.
Cisco names Lisa Golden Glider and then the machine stops working and the metas escape and the plane crashes.
Caitlin starts trying to kill Cisco for locking Ronnie in the pipeline and others do bad stuff and Barry realizes Cold sabotaged the truck. Cold reminds Barry that you should never trust a criminal and rides off.
Joe talks about the difference between The Flash and the Arrow.
Iris begs Eddie to reconsider. Eddie asks Iris to be honest with herself and see what everyone else sees, that there have always been three people in the relationship. If she really loves him, she'll let it end. She says it's over.
Barry sees Eobard outside and runs out there to stand before him. He asks Barry to look back carefully at the wheels he's set in motion. He's only done what he had to do. Somehow, Firestorm and Arrow got word that Barry was fighting Eobard and show up just in time.
He uses his weird ring and it tosses out the Reverse Flash. The RF throws Barry and then gets Firestorm. How can the Arrow compete? Courtesy of Ray Palmer and his nanites that emit a high frequency thingy disables his speed. It works for a while, then he gets ready to kill Oliver and Barry takes off after him and the Reverse Flash chuckles as he falls on a car from atop the building. But he's not laughing as he's shot with an arrow through the back just afterward.
Barry thanks the guys for help and Oliver says he'll need a little help shortly.
