Once Rob saw who had called out to him, the confused look was replaced by a large grin. It seemed that he was bumping into Riannon Pendleton quite a bit lately. Not that he minded, of course. Rather it be her then someone who would just bore the pants off of him. Plus, it was good to fraternize with other houses. Wasn't that quickly becoming the theme of the year? Make friends outside of your comfort zone. Rob was quite laid back and didn't find the task hard at all. Especially if he was to make friends with girls who looked like Riannon.
"Hello," he said when Riannon was closer to him. "Yeah, I was incredibly hungry for whatever reason," he laughed a bit at himself, "You too?" Or perhaps she had been in the library. He didn't remember seeing her when he left the Great Hall.
