Jon took a deep breath, then charged into his sister's bedroom. It was going to get ugly (especially after last time), but it had to be done. He couldn't live with himself if he didn't at least try to get Karyn back to normal.
Karyn stood up, with fire in her eyes. "What the fuck!" she yelled. "I told you to stay out of my fucking room!"
"Sorry, but this is for your own good," he said.
"What the fuck are you talking about?"
He grabbed her arm and began pulling her out of the bedroom. But she struggled.
"Let go of me, you fucking asshole!" she yelled.
"What's all the noise about?" asked a woman standing in the hall. She was dressed just like Jon's mother, but the face belonged to Sarah McMillan. She even sounded like Sarah, although her voice seemed a little bit deeper with maturity. "Jon! Let go of your sister!" she yelled at him.
She's not my sister, Jon thought. And you're not my mother.
