Barry and Iris have a huge fight in this clip from tonight’s all-new The Flash.

In “Snow Pack”, after Barry (Grant Gustin) makes a big decision about their family without consulting her, Iris (Candice Patton) decides to take matters into her own hands.

Meanwhile, when Icicle (Kyle Secor) returns to enact the next phase of his devious plan, Caitlin (Danielle Panabaker) and her mother, Dr. Carla Tannhauser (Susan Walters), must resolve their long-combative relationship to defeat the icy monster.

The Flash airs TONIGHT, April 23rd @ 8PM ET/PT on The CW.
