Mix and Merge: Jon and Karyn Aren't Friends?

Wondering how Karyn had changed, Jon decided to give her a call. "Hello?" she asked. "Hey, Karyn," Jon said. "Who is this? How did you get my number?" "Karyn, it's me. Jon." "I don't know anyone named Jon." "What are you talking about? You ..." Then the line went dead. *I can't believe it. She hung up on me!* Jon thought. He decided that he needed to see her in person. Would Sarah's personality change her *that* much? So much that they couldn't be friends in this new reality? Karyn's own personality was still there, so it must have had some sort of contributing factor to her new merged personality. But what was it that made her different than Sarah? ------ About ten minutes later, he arrived to Karyn's house. From the outside, it didn't really look any different. But he wasn't sure if that mattered. He knocked on the door and when no one opened it, he knocked louder. "Karyn! Open up! It's me! Jon!" Suddenly, the door flew open, revealing a Karyn that was dressed similarly to Sarah McMillan (although she had none of Sarah's jewelry or pink clothes). "What the hell? Are you *stalking* me?" she asked.
