Titled “Null and Annoyed,” the episode will air on April 10 and is described as follows:

“Barry (Grant Gustin) and Ralph (guest star Hartley Sawyer) take different approaches to finding the remaining bus metas before DeVoe gets to them. However, Ralph’s cavalier attitude frustrates Barry and the two clash over what it means to be a hero. Meanwhile, Breacher (guest star Danny Trejo) returns to ask Cisco (Carlos Valdes) for a favor.”

The episode was written by Lauren Certo & Kristen Kim.
