Duets - S4.E13

One-Who-Waits returns and has positive information on the location of Ed's father and takes Ed to the construction site where he works. Ed gets a job and tries to come up with a way to tell the foreman that he is his father. Mike asks Maggie to fly to a mountain range where he thinks he will be able to identify the chemicals that were part of a container spill. A blind man comes into "The Brick" and offers to tune and rebuild the piano but begins to get on Holling's nerves. Maggie tries to hold off Mike's advances by telling him about her "curse."
