From The Grey House:
He unlocked the doors and waited until they were settled, and the car started before asking. “What about Bethany?”
“I can’t have a human friend, or rather, I can’t have a friend that can’t take care of themselves anymore.”
Tears started in her eyes and he could hear it in her voice. Charlie left the parking lot, not wanting to be in a parked car for too long. It invited too many questions. As he drove, he placed a caring hand on her knee. He wasn’t trying to flirt with her, only to offer comfort, as he had many times before.
