Theo wasn't sure and he shrugged uncertainly. "It's more likely that he found you attractive and told you than didn't and lied." he pointed out; it was pretty obvious to him that Greg was physically attractive, even if he personally thought that it was Greg's personality that was more attractive. He had no idea that Greg could be completely unaware of how he looked and he was worried that Greg didn't see the potential danger of his interaction.
He didn't like what Greg was telling him though, shifting uncomfortably in agitation and condemning himself - again - for not staying around. "So, he said he thinks your attractive, that makes sense." he said bluntly, then tilted his head. "Apologised for what? Hating you? Or us, or whatever."
