Later, Brian watches a television documentary that reveals Peggy's past as a top advertising jingle singer of the 1950s and 60s.

While on her death bed, Brian and Peggy share a fantasy intimate moment, but as they are about to kiss, she dies. Meanwhile, Peter grows a beard and learns that a swallow has nested inside it. He wants to shave it off but can't when he finds out the bird is an endangered species. Peter eventually grows attached to the bird and starts feeling maternal. Lois is finally able to convince Peter to let the bird fly away and also teaches Brian about moving on with his life after Pearl's death.
