Wells informs the team that Eiling was experimenting on his men to turn them into super soldiers. Cisco confirms one of Eiling's soldiers, Bette Sans Souci, was at the bomb site. The Flash tracks her down and realizes that she's not setting off the bombs, she is a meta-human who can blow things up just by touching them.

Caitlin tells her that they call people like her Meta-human. Catilin finds that Bette had been shot and that it included a tracker. Eiling and his men show up so Barry has to remove her from the building. Harrison stalls the man briefly allowing Barry, Cisco, Caitlin, and Bette to leave the lab.

Iris is at work when Barry shows up as the flash. He changes his voice to talk to her. He uses his speed to help her clean before sending her to the roof. He tells her to stop writing about him and he speeds around in the darkness so she can't see his true face behind the mask. He begs her to stop but she refuses to.
Barry returns to Star Labs and learns with Bette about how she can't be unspliced with the shrapnel in her body along with the powers now being apart of her. Barry thinks Bette should join the team but Caitlin says that is a bad idea. Barry, however, believes that they saved him and that Bette needed someone.
Barry heads to his lab and spotted Joe inside. He tells him what happened and how he vibrated his voice to talk to Iris. When Barry says he tells Iris everything, Joe tells him that he knows about Barry crushing on Iris for years as Iris was oblivious.

Barry heads to the West home to talk to Iris. Barry tells her vaguely about what happened with Bette and tells her that he was worried and wanted her to stop. She asks him directly and he doesn't say anything at first. He then lies and says that he finally put his family behind him but Iris refuses as she wanted the world to believe in the streak. He then says they shouldn't see each other for a while and she agrees. He then gets up and leaves.
