Ella didn't dare try to struggle or cringe, not even if she could actually do so. She didn't want to cause any suspicion or whatsoever, so she did and said as little as possible. With so many humans around, that was the best option she had to not give away what she really was.
She didn't like pretending to be someone she was not, and hoped that this all would be over soon. She needed help, she knew, but how could she pretend that her kind was evil the whole time? They were not bad, just different from humans in more than just one way. That didn't make then evil, did it?
