Knock Out yelps in surprise at the sound of that voice, spinning on his heel and staring up at the edge of the crater. No, not another resurrected corpse, he has had enough of those, from Dark Energon to Silus to Unicron himself popping up on Cybertron--

Dreadwing doesn't look dead, though, and after a second Knock Out turns off his buzzsaws (when had those come out?) and straightens up.

"... Dreadwing?" he asks, still clearly surprised. "I, ah... never thought I'd see you again." His kind-of-semi-friend-maybe had asked a question, too, right? "And I've... been on Cybertron for several weeks now, actually. Never been here before, but it's good to see some signs of life, even..."

But Dreadwing had died before the resurrection of Cybertron, and Knock Out's gesture towards the Energon is aborted halfway through, confusion clear on his face.
