This was just going bloody great, Adrian was going to completely ruin any chance of getting her in the sack again if he carried on, asshole. For the moment though Graham ignored Adrian and his idiocy and focused on Katie. She didn't know? He frowned, "they weren't there?" That wasn't exactly a good sign. "Maybe they went into hiding?" Was she halfbood? muggleborn? Graham didn't actually know, it wasn't like he'd ever actually cared very much and he didn't ask the girls he slept with. "I'm sorry."
At the suggestion of Gray taking Katie home he looked a touch surprised then realised that a) Alicia probably wouldn't allow Katie to go home alone and b) if he went with Katie then Alicia would stay. Slytherins, they were sneaky like that.
"I'll go with you," he agreed even if she hadn't agreed, eyes flicking to Alicia who he figured would be the deciding factor in all of this. "You should't go on your own."
