"Bro, this is sooo weird" shortly followed by Jon's aunt Rachel, his mother's younger sister. She strolled out of the room with a slight arrogance. She cast her eye over all the women in the room, and spotted Karyn's mom and how she was sat. She strutted over and took a seat opposite her and slouched in her chair, legs spread open.
"Daaaamn, I can totally see her panties" She muttered to herself. It didn't take long to find out who she had swapped with, as Biff Meadows quietly walked out of the room. He walked over and sat next to his former girlfriend and tried to strike up a conversation with her, seemingly employing a heavy amount of flirting. The new Sarah was having none of it, she just rolled her eyes and turned her back to him.
"If I could have your attention please!" Said a voice from the last doorway, "And I'll explain how this experiment will work!"
