After Jon and Karyn entered the auditorium, they spotted the "president" of drama club (Jennifer Taylor) and her twin sister (Sarah Taylor). The Taylor Twins, as they were called, were standing up on stage, looking through a packet of papers. Perhaps it was a script?
Jon looked around and spotted quite a few people that he recognized. It was odd seeing them there, but then again, it was odd for Jon and Karyn to be there as well. He guessed that the flier really got a lot of people's attentions, especially people who weren't interested in theatre and drama at all.
Karyn and Jon took their seats and then a few minutes later, Jennifer spoke into a microphone. "Now that everyone has gotten settled, we can begin."
