James' Sister

Jill had just put on her panties when she heard the doorbell ring. Seeing a pink, silk robe hanging the back of the door, she put it on and went to the front door. She opened the door and saw an attractive, brunette woman in her late twenties standing there with a concerned look on her face. Jill recognized the woman, but couldn't remember from where exactly. Her name was Linda, Jill thought.
"Hi my name is Linda Wilson." The woman said. "My brother James lives next door to you."
"I thought you looked familiar. I'm Jill ." James said, not remembering who he was, but he remembered the name on the passport, "Weston."
"The reason I am here is yesterday my brother had some type of breakdown and I am just trying to find out what happened. Did you happen to see anything yesterday?"

"I don't understand any of this." Linda said crying. "What could have happened to my brother?"
"I don't know." Jill said comfortingly giving her unbeknownst sister a hug, "But I will do what I can to help you find out."

Linda walked down to the back of the apartment thinking that there was something strangely familiar about Jill, but she couldn't figure it out. She knew she had never met the woman before, yet there was something about her like she had known her for years. It was strange, but she was glad Jill was going to help her figure this out.
Linda looked around the back the apartment for some type of clue to help her figure out what had happened to her brother. All she found was a cheap looking medallion under a bush. Giving up on finding anything useful, she slipped the medallion in her purse and went back up to Jill's apartment. Jill had just finished dressing when Linda got there.
"Find anything?" Jill said.
"Nothing useful." Linda said discouraged.
"Sorry, so what do you want to do next?" Jill asked.
"I have an idea." Linda said. "Let's
