[ There's a brief, amused moment when Peter pauses, looking at Megatron but seeing someone else. He remembers now how his grandfather used to give a similar look in those mornings when he was trying to read the newspaper and someone demanded his attention. Peter hadn't thought of that in decades, he tries not to dwell on the memories of the alive family that he had to leave behind on earth, but maybe it's this time of the year that makes him sentimental. ]

I, ehm...[ He smiles fondly and blinks quickly a couple of times, chasing away the memories and giving Megatron a shake of his head. ] That's all right! The point of Christmas is not reciprocation, I just thought you might like it.

[ And judging by Megatron's reaction, Peter made the right call, even if the orrery isn't fully accurate. He looks more and more amused the longer Megatron goes on about how the moons aren't right, but then his expression softens. ]

You're welcome. Merry Christmas, Megatron. Maybe one of these days you can tell me more details about the moons.

[ Now, this is a day to relax and have fun, and Peter doesn't want him to think about the reasons why the moons were destroyed in the first place. ]
