It shouldn't be as amusing at it was to see that flash of absolute surprise and incredulity before the prisoner looks away, but it was. Some might feel unsettled or embarrassed at being... as exposed as he was leaving himself, but truly... The mech before him, smaller, weaker, chained down and weaponless as he was, wasn't enough of a threat to bother feeling embarrassed in front of.

Besides that, he was still hot, a charge running over his plating in a way that meant only a few things, and the little Autobot? Wasn't a worthy opponent even if he let him go and gave him his fusion cannon.

"I have, haven't I?" He chuckled then, optics dimming while he studied the Autobot; graceful, if still sturdly lines and angles and a pretty pleasing colour-scheme. Not too terrible of a view as he brushed just lightly against the outer corona, barely enough to make the energy pulse outwards towards the very fingers touching it. "And yet you have no idea why, and fight blindly... for what?"

Rethorical; most would fight to keep their way of life of course. Fight for it or against it. Once again he dipped his fingers into the outer energy, ghostly swirls tingling against his fingers and his engine dropped down to idly hum on a deeper pitch as he relaxed a bit more into his seat.
