Megatron roughly clears his vocoder, awkwardly standing in the middle of the hallway. Exactly halfway between their rooms, the doors facing each other on either side of the hall.
Optimus' room lies before him, with the blue frame around the automatic door and a handmade nameplate tacked up on the wall. It looked like the kids made it for him, on some occasion. Megatron's room was to his back, the door undifferentiated from all the others but for the additional locks he had installed himself and yet never yet used.
Optimus was just setting aside a gift from the Terrans, a little picture frame that he laid carefully on his desk, when Megatron called for him.
The door was open- as it often was when he wasn't recharging, yet.
Optics flickering absently in a lazy blink, Optimus adjusted the picture frame and then made his way to the edge of the room to lean against the doorframe. "You know," his tone went playful, "usually you just walk in. I'm surprised you didn't knock. ..is something the matter?"
Hopefully something wasn't the matter. Megatron deserved a break, after everything that had went on.
And usually Megatron had no problem coming in and butting up against him like an Earth cat, demanding his attentions. ..and receiving it, of course. As if Optimus could ever deny him anything.
