Editor's Note: The following contains spoilers for 'Superman & Lois'.While there are many stories about Superman, Superman & Lois has taken a less common approach, focusing on the character when he is a well-established hero and the father of teenage twins. The angle allows Tyler Hoechlin's Superman to face different challenges as he and Lois (Elizabeth Tulloch) navigate parenthood and their world-saving endeavors. Over the three previous seasons, the series used this story to its advantage, but the differences in the portrayal of Superman are never more clear than in Season 4. As the show builds towards its ending, Season 4 has already been eventful between Superman's death, General Lane's (Dylan Walsh) sacrifice, and Jonathan (Michael Bishop) developing powers, but Episode 4, "A Perfectly Good Wedding," adds another twist that will impact the rest of the series by showing Superman adjusting to his human heart.
