I caught the wedding ring after I had watched the episode for the third time!
I think that the writers like to tease us with Peter and Olivia. In the last few episodes, Peter and Olivia never kissed. The writers waited until this episode: " The last Sam Weiss to show them kissing. I think that Peter not saying "I love you too" was done on purpose.
The picture on the fridge is that of a family and Peter was crying in that scene. Maybe Peter and Olivia had a child and the child died. I can't wait for next week. The possibilities are endless!!!
