Barry is normal. Harry is totally pissed, pointing the finger at Barry. Everything going on is his fault.
Joe and Iris stick up for him, and Barry agrees with Joe that this isn't all his fault.
Cait is finally calling the killer Hunter. She demands if he talk to her, he take off the mask. He says she'll eventually see he's not a monster. She's there because he loves her. Surely she'll fall in love with him again. It will just take a while.
The Man in the Iron Mask is tapping away at the glass, but Cait doesn't understand.
Killer Flash wanders in from behind.
Wally West wants to know about The Flash. He's hoping Joe can set up a meeting between him and The Flash. Talk about bad timing.
Jesse doesn't want to return with Harry, hard feelings and all that, but he's kidnapped by a meta on his way home.
Petty crimes have risen lately, sparking concerns that The Flash something, says the news.
Killer Frost and Cailin strike up a deal to help each other out.
Griffin Grey is upset because his super strength is also aging him. He's only 18 and looks...I have no idea.
Killer Frost talks a lot like Captain Cold all of a sudden. She and Caitlin have a lot in common.
Wally wants to talk about The Flash again. He's getting a little bit annoying. Wally feels bad, I guess, that The Flash gave up his powers to save him. So I guess that's a decent reason to talk to him, but he must realize the dude's not The Flash anymore, right?
Barry is useless against Griffin, who is using his strength and aging along the way. Jesse is very helpful in the lab, especially since Caitlin is gone. They talk about getting Griffin so worked up that he expends a lot of strength to the fact he's old and feeble.
Barry talks to Iris about her being his first save.
Killer Frost double crosses Caitlin. She thinks he won't need her anymore. But it was all a play to escape. Hunter was onto it and kills Killer Frost. He says if she tries the same thing with "him," he'll die, too.
Jesse and Cisco try to make alterations to The Flash suit so Barry can absorb a super punch, but after all, they can only alter the chest area, and it can only absorb one punch.
They fight, and when the poor dude finally dies of old age, he turns back into his normal self.
Jesse runs and hugs Harry. Everyone's sorry.
Harry and Jesse are living at STAR Labs. Maybe they should get a place to live of their own that they can really call home. Jesse wants to make sure that no matter how much danger he thinks she's in, Harry will never go to the extremes he did before again.
Wally meets with The Flash. But Barry can't shake his face or squiggle his voice anymore. Wally just says he's not going to waste this chance he's been given. The Flash thanks him and leaves.
Hunter decides he wants to widen his scope of how he counts his success. It's no longer body count, but the number of earths he conquers.
