Barry goes out to give gifts to his friends at S.T.A.R. Labs. After Dr. Wells leaves, Cisco informs him that Dr. Wells doesn't celebrate due to that to the tragic death of his wife. Meanwhile, Eddie wonders about Barry's relationship to Iris which Iris responds that Barry is just a friend.

At Mercury Labs, the man in the yellow suit attacks and kills two guards. Barry and Joe finds out it was the same man during a witness statement from a scientist. During a meeting, Dr. Wells thinks the culprit is after Tachyon.

Caitlin runs into Iris at Jitters where Caitlin asks Iris about the Burning Man blogs. Iris then asks Caitlin whether Barry is keeping a secret.

While Dr. Wells asks Dr. Tina McGee for help in loaning the Tachyon as bait, Cisco finishes making the device to capture the culprit. Caitlin asks Cisco to help her find the Burning Man as she believes he is Ronnie.

In Barry's lab, Iris finds Barry staring at the board of clues surrounding his mother's death. She tells Barry that Eddie suspects Barry of having feelings for Iris. Barry dismisses it.
