In this extended new clip from "The Flash," episode 3 -- "Family of Rogues" -- fellow speedsters Barry Allen and Jay Garrick study the wormhole that has opened up in S.T.A.R. labs along with plenty of help and scientific expertise from Caitlin Snow, Cisco Ramon and Professor Martin Stein.
While they know the wormhole is a doorway to Jay's home world of Earth-2, and that Zoom is using it to bring metahumans into Barry's Earth, what they don't know is whether or not it's safe enough for them to take advantage of. Always quick to make a decision, Barry decides to use his speed to test it out.
"The Flash" airs Tuesdays at 8/9C on The CW.
