User blog comment:Flashdancer911/Zoom: who he CAN and CAN'T be... (theory only)/@comment-28835160-20160216172556

Zoom seems to share traits with Cobalt Blue. Cobalt Blue (in the comics) is Barry's twin and is named Malcolm Thawne. He was raised by the Thawnes instead of the Allens. What if Earth 2 Malcolm is Zoom? That would be an interesting plot twist and a huge bombshell for Barry that is remarkably similar to Iris and Joe discovering Wally.
