Re: WHO WENT?
Ben was there. He tried very hard to not be obviously upset about the fact that his mother wasn't there for his graduation. Otherwise, he was his usual anxiously cheerful self. He ate more at Olive Garden than he usually eats and helped make sure everyone made it home in one piece.
Eleven didn't go to the ceremony as she still feels a little squirrely. If Will went, she probably met everyone at Olive Garden after.
