Along with the powerful metahuman named Atom-Smasher, another speedster with the identity of Jay Garrick came into the scene. Garrick had presumably reached Allen to warn him about the wicked speedster Zoom. Garrick's entry to Allen's universe suggests that either the two speedsters are going to work hand in hand as partners or Garrick may turn out as Allen's another adversary in the process.

As per Spoilers Guide, Iris West informed Allen that he needed to allow his friends to help him save Central City as Atom-Smasher attacks the city. Also, Cisco Ramon worked together with Joe West with his Meta Task Force.
