The item in the refrigerator shelf guy just showed Don that other people feel like him, as did the Stephanie character. He perhaps learned that he isn't alone in that feeling, so maybe he learned to accept himself as he is. He won't be running away anymore, as he once did and Stephanie did. Whether he's called Don…

I also saw that Don was wearing a white dress shirt while out there listening to new day..new ideas stuff. Before that scene he had casual shirts one. A hint that he was willing to go back to New York?
