Cisco, Barry and Wells Talk to Dr. Brand in Sneak Peek from The Flash “I Know Who You Are”

A sneak peek from tonight’s (May 2) episode of The Flash has been released. In the sneak peek, Cisco, Barry and Wells try to convince Dr. Brand not to give of her work, but they might not get the chance when an old friend stops by.

Entitled, “I Know Who You Are”, “Barry (Grant Gustin) and the team meet Tracy Brand (guest star Anne Dudek), a scientist, who may be the key to stopping Savitar. Unfortunately, Killer Frost (Danielle Panabaker) is also after Tracy so Team Flash must battle their old friend, which proves to be particularly difficult for Cisco (Carlos Valdes). Joe (Jesse L. Martin) and Cecile’s (guest star Danielle Nicolet) relationship takes a big turn.”
