Maybe he'll get his speed back with some Quick math.
nice pun.
Somehow they're going to have to steal back some of the speed that Zoom has stolen (how does that work anyway?) So, I am betting Jay will get his back at that point, and that Jesse will get some too, to make her Jesse Quick. And maybe Wally will get some too. Oh, and that might also be where Velocity comes from since there was that news story recently about that part being cast...
Of course, all this is just speculation.
