In Flash Season 2 - during Jay Garrick Vs Zoom
We see that Jay's helmet got sucked into the black hole, (which was opened way after the closure of Speedforce hole and Barry returned from past)
But during finale of Flash Season 1, the cap enters the Earth 1 from the wormhole barry opens using the Speedforce (the hole through which Barry went into the past)
Is this a plot mistake? or something that I am missing?
