Ashley hadn't known how to start the explanation on all that she was going to explain to Damon.
When they were both seated, she saw him almost start the car and she became scared. She had to stop him because she didn't feel like it would still be safe going to work.
"I don't think it's safe to go to work again." She said and she was relieved it made him stop.
But he looked at her questioningly. Ashley thought of how to explain, then she remembered that she hadn't even let him know that some creature which was obviously now one of the people after him had come to her dream sometimes before. She had only told that to Natalie the night she got drunk at a bar.
So Ashley thought that would be a good way to start telling him of what had happened just this last night.
