He couldn't the deny the faint flicker of near-trembling tension that flowed through him at those words, but he hopefully managed to hide any proof of it outwardly. He'd really very quickly gotten used to the lack of restraints over just the day or so he'd been free of it when Optimus deactivated it after their Merge.

It just wasn't... right. And well, he hadn't liked, but at least accepted the consort-convict programming before, at least insofar as he'd had to, since the shell-programming had been more important to get rid of.

"Fantastic," Megatron snarled, the sound reverberating with his engine as he threw himself backwards and and to the side, but his processor's slightly slower calculation from being tired led to over-reaching. He tipped backwards, regaining his balance a step or so later, but he'd wasted precious seconds and was not far enough away to avoid Optimus slamming into him.

And then they both met the wall and Megatron cursed, slamming a hand upwards between them, aiming to snap Optimus' helm backwards by catching Optimus' chin in his palm. It ought to do something, even with his lessened strength.

Question was just if it would do enough to let him throw his Prime off, but at the moment the mech felt heavy. Far heavier than he actually was to Megatron, when he was unrestrained.
