In the fifth season, Will and Grace decide to have a baby together through in vitro fertilization. The process is repeatedly delayed through a series of mishaps, however, and Grace changes her mind after she begins dating Leo Markus (Harry Connick, Jr.), whom she marries later in the season. Will is hurt that she does not want to have a baby with him, and the ensuing argument nearly ruins their friendship. Eventually, however, they both realize that they just want the other to be happy, and reconcile.
