It had been a long time since anyone called her 'princess' and Lissa's stomach dropped at the honorific. Who was this boy and how did he know who she was? He wasn't a Guardian, that was obvious, but once she got a good look, she realized he was Moroi. That meant there couldn't be Guardians too far behind. Her heart began to beat faster and she wished that the bond between her and Rose wasn't one way.
Rose! Rose! We have to run again! she thought, hoping that maybe her frantic thoughts would catch her friend's attention.
"I have no idea what you're talking about," she said. "I've been enrolled here since last fall. How did you find me? How many Guardians are out there?"
Her panic was palpable and she only hoped that whoever this boy was, he would give her a head start to find Rose and get out of here before they could be captured and sent back to St. Vladmir's.
