Karen sent him off at the stairs, and Luke didn't make her continue downstairs with him.
When he went downstairs, the young African-American girl snuck over and asked in a low voice, "Karen, who's that? He looks quite handsome."
Karen turned around with a smile. "His name is Luke. He just moved here, and he lives in the building across the street. Charlie didn't mention him to you? Claudia, it seems that Charlie is keeping a lot of secrets from you."
Claudia was stumped for a moment, before she suddenly made the connection.
Her mouth dropped open. "He's the Luke who caused me and Charlie to be roped into the volunteer work?"
Karen made a zipping motion across her mouth. "It's good that you know. Of course, you can share it with Charlie."
She then went back into the office.
This girl was Charlie's girlfriend, and she was only fifteen.
