Will & Grace
24 Episodes as Leo Markus 2002-2006 Dr. Marvin "Leo" Markus, portrayed by actor and singer Harry Connick, Jr., is a Jewish doctor and Grace's husband since the fifth season. Leo meets Grace Adler in Central Park while she is on her way to be artificially inseminated with gay best friend Will's baby. When Will finds out the Leo and Grace are dating, they have their biggest fight of the entire series, in which Will tells Grace to move out. Thanks to Jack and Karen's meddling, they forgive each other and Will accepts Grace's relationship. In November 2002, Grace and Leo were married at a group ceremony in Central Park, which was supposed to be broadcast on The Today Show. It was later revealed that the ceremony was not legal, but the two officially marry at a ceremony soon after. Leo and Grace's relationship was a constant source of tension between Will and Grace. Leo's true first name is Marvin, as is revealed by his mother at the reception of Grace's and his wedding. According to The Nation Magazine, this was the first time in television history that a Jewish protagonist had married inside the faith. The marriage failed less than two years in, when Leo revealed that he had a one-night stand while working in Cambodia for Doctors Without Borders. After Leo came clean about his affair, Grace briefly considers continuing their marriage but quickly decides she wants a divorce. Leo reappears during season eight (a little over a year after the divorce), in the episode "Love Is in the Airplane," in which he and Grace have a sexual encounter on an airplane after coincidentally ending up on the same flight to London. The result is Grace's pregnancy, as discovered in the season eight episode "The Definition of Marriage." However, a couple of months later, when Grace meets Leo with the intention of telling him that she is pregnant with his baby, he informs her that he is engaged to another woman, so Grace decides not to tell him about the pregnancy. In the series finale (May 2006), however, Leo tells a heavily pregnant Grace that he loves her. They subsequently raise their daughter, Lila, together. Lila ends up marrying Will's son, Ben, whom Will raises with his domestic partner, Vince.
