In "Who Is Harrison Wells?," this week's episode of "The Flash," Team Flash gears up to investigate the connection between Harrison Wells and the Reverse Flash, but one member isn't very convinced.

As Barry (Grant Gustin), Joe (Jesse L. Martin), Eddie (Rick Cosnett) and Cisco (Carlos Valdes) begin their investigation and dig into a pizza from Coast City's finest, Caitlin (Danielle Panabaker) expresses her distaste for the situation and leaves abruptly, causing some concern among the others.

"The Flash" airs Tuesdays at 8 pm EST on The CW.
