Catching Carson with Jackson had put a serious dampener on Rodney's mood. Carson had looked awfully terrible, and it upset him that there was nothing he could do. He'd trudged back to the lab, trying to get some paperwork done. He couldn't really focus, and then he found Sheppard's email, asking him to show up at 5 am. He was smart enough to realise there was no way out of this, if he seriously wanted to be on Sheppard's team. It was late, so he decided not to reply to the mail, but to make a detour to Sheppard's quarters on the way to his own rooms.
He switched off the computer, and left the lab. Going jogging at 5 am really wasn't the thing he dreamed of doing, but then, it couldn't hurt to get into shape. Tiredly he trudged through empty corridors and hallways towards Sheppard's quarters.
