Papa Luthor stalks into Lex's house. Lex asks why his father is in Smallville. Papa Luthor says that he knows about Lex's "excursions to the Summerholt Institute." Despite the fact that it appears to be lovely and sunny outside, there is the most roaring fire I've ever seen raging away in the fireplace. Lex wonders how his father knows, and Papa Luthor admits that Clark told him. Man, do the Luthors love stained glass, or what? And why does everyone on this show hate overhead lights? Anyway, Lex says that Summerholt is a respected institution, which Papa Luthor laughs off. He says very seriously that Lex's mind is still fragile, so why should Lex risk his sanity? Lex knows that his father couldn't possibly have personal concern for Lex's health. Papa Luthor says that the treatment could trigger another psychotic break. This sends Lex into another memory. Little Lex eavesdrops on his parents. His mother drops a teacup, and his father sends the maid to clean it up. Papa Luthor coos over Julian and tries to get Mama Luthor to hold the baby, but she refuses. She thinks that Papa Luthor inflicts psychological damage on his children, and has chipped away at Lex's spirit. Papa Luthor says that she has made Lex weak. Mama Luthor thinks Lionel will pit the boys against each other and make them compete for his affections, and she wants a divorce. Papa Luthor says that he let Lex come home for her sake, so she needs to try to be a mother. She reluctantly takes Julian as Papa Luthor says that they will try to be a family, and that she should take the night to be alone with Julian and bond. Then, Papa Luthor spots Lex spying. Lex runs into the room and stares at Julian, who is crying. Back in the present, Lex tells his father that it was an accident, as the camera goes around and around and around.
Another memory. In this one, Lex stands over Julian's crib. Apparently, someone put a blue light in Julian's crib, which seems like it would hurt the baby's eyes. Papa Luthor walks in and asks what his boys are up to. Lex turns around and weeps that Julian wouldn't stop crying. Papa Luthor asks Lex what he's done, and walks to the crib. He looks inside and asks Lex again what he's done. Papa Luthor starts crying, but then gets a creepy look on his face and turns around, snarling at Lex, "What have yoooooou dooooooonne?" And then he punches Lex in the face! Awesome. Back in the present, Lex falls to the floor. Papa Luthor wakes Lex up and says that he's going to call a doctor. Lex insists that he's fine, and swigs some water. Papa Luthor asks if this is a side effect of the treatment, and that Lex is playing with fire. Lex still thinks his father just doesn't want him to remember those seven weeks. Papa Luthor says that isn't it, and that it's always been Lex's weakness that he dwells in the past. Lex yells at his father to get out, and Papa Luthor leaves.
