Waving one hand both in a dismissive motion and to lay it on Orion's shoulder to steady himself, Megatron grimaced. Felt unaccountably... exposed, which could only partly be explained by the fact that while his spark chamber was still closed, it was now bared for all too see.

Luckily, 'all', here, was only Orion.

"Fine," he snaped, resisting the urge to close everything up just to alleviate the feeling of being bared, "I'm fine." Instead he used his other hand to feel around inside his open chest, frowning at the end of the key sticking out slightly.

That it'd disappeared as far in as it had, however, was worrying enough, because as far as he knew, there shouldn't have been any space.

There might also, maybe, be more ports than he remembered from last, but he was honestly not sure - he hadn't looked at himself that closely very often, and remembering what things felt like when explored with his hands only was harder.

"I have no idea what it did, but..." and here Megatron paused, took a deep vent in, flooded his systems with additional energy, and carefully grabbed the end of the key and pulled.

Or tried to.

Didn't get very far before he ended up gasping, gritting his teeth on the pain and the key not budging.

"It seems it's staying where it is."

He straightened up and let go of Orion, closing his chestplating up.
