Ava walked towards his car nervously. She's never snuck out like this before and she was wondering why he was out to see her at this hour.
Tristan was irrational when it came to Ava, he couldn't believe that he was outside her house right now, just like a high school student waiting for his crush to peer outside her window. But he couldn't stop himself because he needed to see and talk to her. That man she drove off with this morning made him very jealous.
He did not think that she would come out and see him, it made him very anxious. But he was going to wait all night if that's what needed to be done to see her. He knows that he won't be able to sleep without seeing Ava.
He got out of the car when he saw her walking towards him, opening the door for her so she could sit inside the warm car with him. He was wearing one of his unreadable expressions, and Ava did not know how to gauge the situation, was he mad at her?
