IMHO, they ended up in a plothole. Hunter was stranded on Earth Two with Reverb dead and Cisco gone, which is why he waited for Cisco-1 to open the breach... Then, two episodes later, he just opens a breach himself to run away from Harry's vibrational device.


 * >"Hunter told Joe that after taking the Velocity drug, it made him fast enough to cross over to other worlds by creating breaches"

This is also contradictory to info from "Versus Zoom", when he said that he specifically went for the opportunity on Earth One because the breach opened on itself after the whole singularity crisis.

Best I can do to handwave it is that Hunter's condition worsened after Team Flash left Earth Two, so opening a breach by himself would be dangerous for him. After getting Speed Force from Barry, this negative factor was negated, allowing him to open breaches at his own leisure. Why he does it just like Cisco (by "punching" a hole in reality), instead of like Barry (by running too fast and ending in a portal) is unknown.
