I believe that Barry will close the wormhole, but some villains from other dimensions will come through, such as a Caitlin Snow coming from another dimension as Killer Frost. Killer Frost was glimpsed at during Barry's run in the Particle Accelerator. Cisco will probably be able to sense these new villains, considering they are coming from other dimensions, because of his newly found power.
