Theo was tired, and not just because of the extra 'exercise' he'd been doing in the night without his knowledge. This stuff with the Muggleborns being catalogued was making everyone jumpy and that made Theo twitchy; nevermind the fact that his dad was still sending him headache inducing owls. He suspected that the only reason he hadn't been pushed into something unsavory by his dad just yet was because they were still trying to get the higher ground in the mindgames of war that they had going on at the moment.
He put his chin in his hand and didn't look round as Draco came in. Since Greg had startled him that time on his bed Theo had stepped up his game and his hypervigilance sometimes almost bordered on psychic, especially when he was supposed to be safe and at rest. And thinking of Greg, well, he was probably the only situation Theo had any grasp on anymore.
