He didn’t after Robert left Rumple threw the hair on the ground and said something like small items can mean big things in that sarcastic tone of voice. He was just putting on a show because he saw himself in Robert. It was one of the best Rumple moments in a very long time. I miss that aspect of Rumple where he does not want anyone to see his vulnerable side but yet the audience gets to see that under the beast their is a grieving father.
