4. When Irish Eyes Are Killing

Complete story — includes the ending

Patrick Sullivan ( Julian Stone ), an old friend of Lois, arrives in Metropolis and he makes clear that he is in love with her and asks her out. Lois accepts his offer to make Clark jealous. In the meantime, rare antique items are being stolen from different museums and a deposit box. Clark puts the pieces together and tells Lois that Patrick is the one who steals the items in order to make a Druidic sacrifice using her as the human sacrifice, but Lois believes that Clark is just jealous. Clark is proven right and Superman saves Lois at the last minute and also destroys the mask with the emeralds that Patrick stole to give him the power to make the sacrifice. At the end of the episode, Clark tells Lois that he was wrong to break up with her, and that he will always love her. When he tries to get back together with Lois, she politely, says no, saying that she doesn't want another heartbreak from him, for although she survived this one, she doesn't think she can survive another. He leaves, as they both wonder the future of their relationship.
