It was an utter joy to have everyone back. Noise. That was what Greg had been longing for the most without even realizing it. The constant buzz of voices in the Great Hall, the hallways and in the common room made him feel good; he was still cross as could be with his brothers. But for as irritated as he had been, he had not bullied the younger students that were stuck there with him. Oh, he'd made a threatening gesture at a few, throwing his chest out in a bluff, much like a bull ready to charge. But the students' reactions of terror were enough to give him great satisfaction; even a mad dog look would evoke a squeak from a normally placid lad. It had cheered him up some, but it was really the sounds that did the trick for him, improving his feelings immensely.
He'd gone off flying with some of the lads, and hadn't been able to find Millicent yet; he'd wanted to fly with her and speak to her, to get some solid advice from her about things. And he had found Draco, with considerably restrained joy, much like a puppy who's lost its owner and upon seeing him, waggles its tail so much its butt shakes. He'd followed Draco about, and found Vincent and felt much much better right away; the sheer act of the habit was a bit of a balm on him. And it kept him from looking for Theo.
Greg wondered what had happened to Theo as he left the common room later that night and entered their dorm room. Theo's bed was occupied, and Greg hesitated to approach him, still confused as to how he stood with his friend. For all that had occurred between them, intimate and not, Greg still thought that Theo just wanted to be friends. He had come to his own illogical conclusion that not talking about it at the Nott home meant not talking about it ever again, period. And Greg gave a small sigh, a mixture of regret and sadness as he had made his way to bed.
Greg had not yet fallen asleep, lying awake being comforted by the sounds of others around him when he thought he saw something move out of the corner of his eye. He sat up quickly, and watched as Theo moved past him, walking. His eyes followed the other boy's form and Theo moved to the end of his path and turned, reversing and walking back. It was erie; Theo was so silent, like one of the ghosts that drifted by them in the halls. Greg watched, silent himself, unsure as what to do. Theo reminded him of a big cat, like Greg had seen in a circus once, pacing and pacing.
As Greg watched, he felt this ping of protection and some deeper stronger emotion start in his center; this was not normal behavior, even Greg realized it. But the idea of seeking out Professor Slughorn and asking him for some help didn't seem plausible. Greg wondered if Theo was caught in some kind of hex or spell; Greg thought he looked like a man walking asleep. And he did the only thing he could think of.
"Theo?" he whispered quietly, "Theo, come here. Are you okay?"
