Anna heard the comment as well and decided to try and see where his mark was when they got back and he was fully clothed. As he explained where his apartment building was, she nodded, getting a mental picture. "A friend used to live there. I think I remember how to get into the area." She agreed, hiking herself up a little so she could see through the back window of the car as she backed out. 

She then noticed she was around the same level as his face and decided to be a bit mischievous. After she finished backing out, she turned to him and quickly kissed his nose before settling back down and driving away, keeping her face nonchalant as if nothing happened. She had to fight the urge to smile victoriously though. She couldn't even see his face until they hit a red light, if they hit one.
