Justin is present, which is the most that can be said for him. He might look at home in the neatly-tailored suit he's wearing but that doesn't mean he's comfortable. There's nothing about dances that doesn't put him on edge. If Angela hadn't insisted that he show up, in fact, Justin would have happily stayed at home with a book.

He might be present, but he's not going to have a good time.

For a lack of anything better to do, he plants himself as far away from the festivities as he can get without leaving entirely.
