User blog comment:Kir the Wizard/Reverb and Kille Frost Return?/@comment-26624146-20160515135951

I know how they'll come back. Hunter Zolomon traveled back in time and retrieved a younger version of himself and somehow disconnected him from his own timeline, so the older Zoom wouldn't die when he murdered "Jay". Maybe Zoom goes back to retrieve Reverb and Killer Frost before their deaths and as a result actually resurects them in a sense, maybe promising them Rupture and Deathstorm back if they serve him.
