In this scene John Proctor and Abigail are talking about the love relationship they have or that they once had.
I've seen you outside my window, you cant say you don't care for me.
I never loved you.
John Proctors wife is putting a bad reputation on Abigail's name because she had suspension about an affair between them while Abigail still worked for them
Your wife is blackening my name. she is a horrible person
DO YOU LOOK FOR A WHIPPEN'?
Betty "wakes up" because she hears the argument that is happening.
