Lex creates a giant kriptonite encrusted Island and stabs Superman with Kriptonite. Superman falls into the sea and it looks like curtains for him when Lois and her husband Richard come and rescue him. Lois takes the Kryptonite out and Superman, half recovered goes back to the island, lifting it up with all his strength. Lex and his buddies go to leave but his henchman get killed and he and Kitty leave in a helicopter, Kitty dropping the crystals as they leave. Superman throws the island from Earths atmosphere and tumbles back to earth with a thump, leaving him in a coma. Superman lives and finds out that Lois Lane's son is his. He says the same thing to the boy (the son becomes the father and the father becomes the son) that his dad said to him. It is left very open at the end, for sequel's sake I take it, but Lois makes it clear she wants Superman in their lives and her current boyfriend is out of the picture. She asks him whether he she will see him around and he replies 'I'm always around Lois' and flies off.
