was ellen scared when she had to stay at annemaries house

Ellen is afraid because the sleepover (a very extended sleepover) means that war is upon them, and her parents have gone into hiding. It isn't a game anymore; it's very real. Her first night there, soldiers arrive to question them. Ellen hurriedly removes her necklace (the Star of David) and clenches it in her hand. They question the girl's coloring, the differences in their looks. Luckily, their daughter Lise who'd passed away had dark hair, and that's how they convince the soldier Ellen is one of them.
