A/N Sorry for the wait! Please review so that I know whether to continue or not.

Elizabeth:-

Elizabeth screamed as she looked through the mirror into the strange room. Where was she? How did she get there?
"Sarah?" Elizabeth continued to scream. "Sarah what's wrong?" A girl poked her head round the door and clasped her hand to her mouth as she saw Elizabeth step out of the mirror and hesitated before speaking again.
"Wh... who are you, and wh... what did you do with my sister?" Elizabeth looked at her in surprise.
"I beg your pardon?" The girl shook her head and sat down on the bed. She looked at the girl more closely before speaking again.
"Who are you? I mean what's your name? You look kinda familiar." Elizabeth cleared her throat.
"My name is Elizabeth Swann. I live in Port Royale and my father is in the Royal Navy. How, may I ask, are you?" The girl's jaw dropped.
"Elizabeth Swann! Wow! From Pirates of the Caribbean. Well, umm, I'm Lori Beverstock and I live... here."
"Where am I?" Elizabeth asked quietly, her lip trembling. Lori explained that she was in the 21st century and tears began to roll down Elizabeth's cheeks. "I just want to go home." She laid a hand on the mirror, but it felt cool and solid.
"I think we'd better get you changed." Lori indicated Elizabeth's nightgown and she sighed. "I wonder where Sarah is." Seeing Elizabeth's puzzled look she explained. "Sarah is my sister. She must have swapped places with you."
Just then Elizabeth noticed the poster of Orlando Bloom hanging on the wall. "Will?" Lori shook her head.
"No. Orlando Bloom. He plays Will in the movie." She hastily continued. "That's a moving picture. Tell you what, we'll watch Pirates of the Caribbean tomorrow. After all, it is Saturday." She helped Elizabeth to change into a pair pf pyjamas and tucked her nightgown into the wardrobe.
"It's weird. You look like Sarah but there's something about you that's different. I mean your hair curls but it's the same auburn colour as Sarah's. She has straight hair. You have almond brown eyes but hers are greeny grey. You are a little taller than her but you have the same body shape. I'd like to see what she looks like. "Lori broke off.
Elizabeth was gazing around the room, taking in the computer, the television, the DVD player, the stereo. She picked up the Mini Disk player which was lying on the desk and turned it over. She pressed one of the buttons and it sprang to life, a gentle tune soaring out of it.
Lori strode over to the computer and turned it on, tapping her fingers as it loaded. Elizabeth was gawping at it so she showed her the wires and explained the basics of how it worked.
"You have a lot of knowledge for one so young." Lori blushed.
"How old are you? I'm sixteen." Lori noted that she was eighteen, the same as Sarah. "Birthday?"
"21st August," Lori paled. She turned her attention back to the computer which was beeping furiously. "Damn machine." She switched it off. "Tell you what, let's get some sleep and then we can sort this out in the morning."
Lori waited until she was settled and then went back into her own room, her mind in turmoil.

A/N Okay, so I'm not really eighteen but for the purpose of this story I am! Nor do I have a sister but Lori is my cousin so close enough. I just felt that I knew POTC well enough but Elizabeth knew nothing about the future so she needed a guide.
