CW | 8:00 pm

After Barry (Grant Gustin) discovers that he suddenly has acquired the power of speed thinking, he attempts to use that new gift to save Iris (Candice Patton) in the new episode "The Speed of Thought." While Barry revels in this new ability, though, Cisco (Carlos Valdes) is reluctant to trust it. Elsewhere, Eva (guest star Efrat Dor) is forced to confront a shattering truth.
