Overview:Vaughn tells Corinne that he saw her on the Pearadyne security tapes- talking to his mother. He becomes angry at her when she denies ever seeing his mother. Z explains to the science club about friction- how it can cause things to fuse together. He demonstrates with two blocks of metal. When the lesson is over, Corrine leaves quickly, followed by Vaughn who doesn't believe Corrine is telling the truth about his mother. As the remaining science club members are leaving, they notice that the metal blocks have fused together, despite being set apart. Something clicks and they go to warn Vaughn and Corrine, but it is too late. Vaughn grabs Corrine's wrist to stop her, and suddenly they are fused together and can't separate. Now in order to come unstuck, Vaughn and Corrine must cooperate to find out what really happened when Corrine went through the wormhole.
