Sharp movements from the outside alerted Arianna that someone was right outside her door. Good thing Elijah left already or she wouldn't know how to deal with that.
Her mind was spiraling and Arianna found herself unable to breathe. What was she going to do? She finally saw Elijah's face. In the past, she would have been excited at the prospect of escaping, but not anymore, not now that she has a life with Marcel. But then, she couldn't tell Marcel about Elijah either, no, she couldn't. He would kill him.
God, what was she going to do? Arianna ran her hands through her head in both confusion and annoyance. She might have seen Elijah's face but there was no way to communicate with him and change his mind.
