At breakfast the family erupts over Nathan's late-night behavior. Grace admits, "Don't blame Nathan. It's my fault," saying she should have stopped him, while the parents tell Lucas to ignore Nathan and let him fend for himself. The scene shifts to a chess game where Lucas plays a surprising, brilliant move; his father praises his improved skill and calls him the family's genius. Before they can process the praise, someone detects a sudden, foul odor in the house, and the episode ends with the family alarmed and the source still unknown.
