Benjy still wasn't entirely sure what he thought of these visitors from the future. He certainly didn't go out of his way to avoid the ones in the castle, and he wasn't pretending like they weren't here either. However, he definitely wasn't going out of his way to make them comfortable either. He didn't like the idea that they could possibly mess with the future if certain things were told, and he definitely didn't like the possibility that he could learn of his own future. Benjy just did not want to know.
Nonetheless, he found himself at the mixed deathday party that everyone had been invited to. He blamed his status of Prefect for forcing himself to attend tonight, that his presence might be needed to maintain order or something. As it was, he was simply walking around the party, making sure that everything seemed to be going all right.
