Iris West was pissed off with Caitlin as Caitlin had lied to her when she asked Caitlin if Barry was hiding something from her and Iris found out that he was the flash. She was also pissed that Caitlin had lied to her about the burning man as it was later revealed that it was Caitlin's fiance. Caitlin had told Iris that he died and that pissed her off even more because she didn't understand what Caitlin would lie about something like that "Caitlin! We need to talk now!"
