Greg's cheek flushed slightly, his defenses rising, "He is a bit better yes. Better than those nonsensical ramblings he can get into," and Greg cast an accusatory look at Draco, who seemed just as ready to believe Snape as not, "You've read some of that rot he's written. He's at least making some partial attempt at understanding what is going on!"
Greg put an arm around Theo now, his hand soothing Theo's back, and he turned his attention away from the visitors, knowing Theo needed his support, "Look, they've come to lend you a hand, Theo. Prof..Headmaster Snape needs to give you a sort of....examination. Let's get you sitting," he said, and he glanced at the other two as he led Theo towards the small couch, "I'm not going to leave you alone though. I'll be right here," he said as he sat down besides Theo and then let his hand stay around Theo's shoulder, a protective gesture to help the thin man feel more secure.
"What do I have to do?" he said, and Greg turned his eyes towards Draco, and frowned for a brief moment, "You are here. Is it because you are in charge of his guardianship?" he asked, realizing finally that it might be a bit odd for Draco to just show up at the hut now, at this one particular moment.
