Sam watched the monitors to Andie's quarters. It looked the same as it always did: the bed unmade, stacks of borrowed DVDs near the TV, books of assorted topics neatly on a shelf, a blankets she had insisted on having after watching all of the old Charlie Brown cartoons, and a fifty dollar teddy bear Jack had bought when he took her into a toy store in a fit of madness.

The only thing really wrong was Andie herself. Most people wouldn't have noticed the eccentric young woman was acting any differently, but all of SG-1 could. There were little clues they had picked up on—such as her claiming to be someone else, her eyes were a different colour, and refused to open a door for herself—but what really gave it away was how she was reading.

On any normal day, Andie read on her back with her feet in the air and twisted around every five minutes to find a more comfortable position. This imposter had sat perfectly still in a chair, with her feet flat on the ground, for the better part of three hours.

"There is nothing physically wrong with her!" Janet insisted. "Every scan and test came back normal—for Andie. Bizarre for the rest of the world, but fine for her."

"There has to be something!" Daniel countered, on the verge of pulling his hair out. "That's not her! You don't just suddenly start acting like someone else without a reason."

"Maybe she knows the reason," Sam said quietly. Everyone turned to stare at her. She hadn't spoken since she informed Gen. Hammond something was wrong. "Did anyone bother to ask her?"

The girl looked up when Sam, Jack, Daniel, Janet, and Teal'c entered the room. She smiled serenely and set her book aside. "I was wondering when you would finally show up. First the tests, then the talking, is that how it usually goes?"

They exchanged looks before Daniel dared to ask the question, "Where's Andie?"

She chuckled, something in the heartlessness of it striking them. "Oh, she's still here," she said, tapping the side of her head. "She just needs a rest after the shock you gave her."

"We gave her?!" Sam demanded, held back in place by Teal'c.

"Who are you?" Jack demanded. She smiled again and touched the necklace that Andie always wore around her neck.

Daniel shook his head in confusion. "Bastet? How can you be her?"

Teal'c's eyes narrowed as he watched her. "Bastet was killed by Anubis nearly three thousand years ago."

She grinned evilly. "Well, I managed to hang on."
