9x10 - Little House on the Prairie

Laura's childhood friend, Jane Canfield, comes back to Walnut Grove. Although she is blind, she falls in love with Mr. Edwards, a person who was old enough to be her father. Jane then undergoes an operation which allows her to see again. After a lot of soul searching, Mr. Edwards tells Jane that she should go out and find herself a better life. At the end of the show, we see Mr. Edwards in the distance watching Jane leave on the stagecoach.
