Louis poses as Harvey and goes on an interview with the prospective client. 

He gets the "best lunch ever" and asks for everything. 

He tries to make everyone laugh, and they do, because he's supposed to be Harvey Specter. 

Harvey realizes what's going on and sets out to get some revenge, so he gets Samantha to pose as a secretary and he gets a fright. 

Harvey ultimately says that it's fine, and he'll forgive him. 

Harvey and Samantha subsequently go on a road trip to try to find out more information about her father. 

Once there, Samantha learns that her father did not know she existed. He says that her mother was a firecracker, quite like her. 

On top of that, her mother died when she was two-years-old, leading her to believe that she was not in the system from birth. 

Instead, she entered the system after her mother's death. 

Donna asked Alex to break the law to get a painting for Harvey. He did so, and Harvey was happy that she did. 

Everything made Harvey contact his mother, and they had a nice chat about how they were getting on. 

Harvey's mother then asked her son to stay on the phone with her.
