Pellaeon can feel eyes on him. He knows Thrawn has been staring at him from across the bridge for quite a while now, but he's doing his best to ignore him. He's still annoyed from this morning and he's doing his best to subtly let Thrawn know he doesn't appreciate certain choices he's made recently.
Maybe those choices have to do with the fact that when Pellaeon wants to stay in bed late and fool around a little he gets a five-minute speech about duty and timeliness and whatnot, but when Thrawn wants to do that then it's "for the cause".
Call him petty (much like Thrawn had that morning when he left him alone in the bed without so much as a helping hand), but this double standards nonsense is a load of bantha shit.
And the both of them know that. It's just that some people think they can pull that kind of a stunt and not get called out on it.
So he'll endure Thrawn's halfhearted glare during their shift with a smile, because he knows that when they talk about this later it'll be no contest. He's already won because he's right.
And he thinks he'll celebrate this victory by staying in bed quite late tomorrow.
