With the whole thing about him being back, I need someone to confirm this.
It was stated in Flash: Rebirth that Barry was in fact, the engine of the speed force.
Now in the new Flash comics, Specifically Vol 4 issue #8, It is stated that Barry is the "release valve" for excess energy in the speed force.
SO, if BOTH is TRUE, HOW does this exactly WORK?
if one of them is false, someone PLEASE correct me.
