AceShowbiz - "Superman & Lois" didn't waste time bringing Superman (Tyler Hoechlin) back from the dead in its final season, but a major character had to sacrifice themselves to make it possible. [SPOILER ALERT] In the emotional episode 3, "Always My Hero," it was revealed that General Sam Lane (Dylan Walsh) had died a hero's death.

After being shot by a rogue Department of Defense soldier, Lane injected himself with a serum created from Superman's blood. He then sacrificed himself to Doomsday to protect his family and help revive Superman.

His sacrifice led to Superman's heart being replaced with Lane's own, ending the episode with Superman opening his eyes. However, Lara, Superman's mother, expressed concerns that the human heart may not work properly.
