Grey could've sworn he felt a shiver run down his spine when V confirmed the capabilities of the Humanoids. In fact, that was the reason why Humanoids were hard to take down in a one-on-one fight. Even Outclass and Superior Humanoids would take at least ten people to take down and that's barely making it. The workers of the Nexus Corporation were just lucky that they were sent to test newly built Humanoids so they don't know much about fighting humans. This was also the reason why Red was able to take down Outclass and Superior Humanoids in the Runners Survivors. If it were outside, Red would've had a much harder time since the Humanoids in the war are tenfold stronger than the ones in the Runners Survivors.
"Quick here," V motioned jumping towards one of the buildings but at the last second, he grabbed the edge of the rooftop where they were and waited. Thanks to Grey's fast reflexes, he was able to mimic what V did.
