Company Man - S1-E17
Continuity mistake: At the end of this episode, Noah is having a flashback. It shows Claire helping him pick out his new glasses. In this scene, Noah first tells Claire that she is adopted. However, in the episode "One Giant Leap", Claire tells Brody Mitchell that her parents told her that she was adopted when she was really little. In "Company Man" she is around 14 or 15 years of age in the flashback.
