As she was leaving, Harvey's secretary's phone rang, she picked up.
D: "Harvey Specter's office." She heard Harvey giggled.
H: "Hi."
D: "You're an idiot." She giggled.
H: "Maybe, I just wanted to test you."
D: "And I passed the test?" He said looking at him.
H: "Always."
D: "Good."
H: "I liked you very much as my secretary, but I like you much more as COO."
D: "Only as COO?"
H: "Mhm... No,"
D: "Like what then?"
H: "What are you wanting me to say?"
D: "I don't know."
H: "It's not a conversation we're going to have on the phone."
D: "Ok, I take it." She made a pause. "But, no matter what we are, I'm always going to take care of you... Answering your phone is just one detail."
H: "Thank you, Donna."
D: "I don't have a hard time picking up the phone."
H: "I'm not saying that."
D: "I know."
They stood silently, staring at each other, smiling and listening to each other's breathing on the phone, until Samantha interrupted them.
