Damon had decided to walk you home from the Salvatore boarding house. With all the vampires lingering in and around Mystic Falls, it was ill advised to leave you undefended. It ended up being necessary when you were nearly hit by a car. After that, it didnt take long to realize you had been compelled.

"I'm taking you back to the boarding house."

He picked you up and began walking back to his and Stefans home.
