User blog comment:Flashdancer911/Zoom: who he CAN and CAN'T be... (theory only)/@comment-24578309-20160215162513/@comment-27129692-20160216005217

Yeah he's the only character thus far who hasn't been 'teased' or seen, Eddie and Henry appear on the speed dial and pretty much everyone else's counterpart was featured in 2x13 - and that leaves Wally (unless he's the man in the iron mask, let's say he knows his father is Zoom so he's been held captive and silenced)
