This may have been done before, I don't know, but it was in my head and wanted out.

"Samantha, we need you to summon your demon to help us out." Samantha Malory's master said.

Sam nodded, stepping into the pentacle and beginning the summoning. It was a crucial time in America. The war in Iraq was going badly, and at home people were unhappy. Protests happened regularly. Sam would probably be dispatching her djinni to break up a protest or something. She didn't really care what task she would be giving it. It was just a demon, after all.

In the pentacle opposite her, the djini was forming. It took on it's usual guise: a girl, about 18, with short, dark hair and a fiery expression. The clothes were from a different time, and looked like the girl might have belonged in London. The demon blinked. "Hello Master." It said with contempt.

Sam scowled at the djini. "Hello Bartimaeus."

Author note: I don't know if that was clear, but basically, Bartimaeus started using Kitty's guise like he did with Ptolemy out of respect. I just finished "Ptolemy's Gate" and I did not like the ending. Ah, well, I can always rewrite it in fanfiction…
