Piper felt the ticklish feeling of Leo's magic on her head. " Wha-?" she asked.

" Lay still," he ordered.

" Where are we?" she wondered when Leo moved his hands away. " The living room?" It looked like the living room, but dirty and dust-covered.

" What happened?" asked Paige, sitting up. " I feel like I slammed into a wall."

" Congrats, you did slam into a wall," Piper greeted her baby sister.

" Apparently," Leo said, putting a hand to his head and wincing when he felt blood, " we entered an opposite dimension."

" Huh?" Piper said. " I just woke up, Leo."

" This world-" Leo gestured to dirty manor, "- is the opposite of ours."

" So those witches- they were just like us?" Phoebe asked.

" Pretty much, just evil."

" And you were a Darklighter," Piper wrapped her arms around Leo's neck.

" Exactly," he agreed. Piper could tell her husband didn't like the idea of an evil Leo running around. " They've switched dimensions through the mirror." Leo gestured to a replica of the mirror on the wall.

" Fabulous," Paige replied wryly.

" What do we do?" Phoebe inquired worriedly.

Leo shrugged. " I've heard of this dimension, the Shadow realm. But doubles aren't aloud to switch sides."

" In case you just tuned in, evil doesn't always do what it's supposed to," Phoebe reminded them all.

" What do we do?" Piper asked as Leo pulled her to her feet.

" If they're us, they've got to have a Book of Shadows, right?" Paige suggested. "Book," she called, using her magic. The Book of Shadows orbed in her lap. Piper looked on as Paige flipped the pages. Spells to steal powers, to kill good witches and mortals made her chest twist.

" Never mind about the book idea," Paige said.

" We have to get back to our world, before our doubles wreck it," Piper announced. "Where do we go? What do we do?"

" Ahem," a feeble voice said. The girls and Leo turned to look at a pale, skinny man who looked remarkably familiar.

" Who the hell are you?" Piper asked.

Phoebe looked like she was other to laugh or cry. " Cole?" she choked.

The man straightened his glasses. " Yes, that's me, Cole Turner, Charmed Ones specialist." He squinted at them. " You are the doubles? The good ones, I mean."

" Yes," Paige told him, giving a wary look to her sisters.

" I'm, um, here to help you." He smiled and began to sweat.

" You trust him?" Piper whispered to Phoebe.

" Yeah. He's so…sweaty. He's definitely OK," Phoebe whispered back.\

Piper nodded to Cole. " OK, Cole. Get us back."
