Iron Forged in Fire: Part One - S1-E1
Continuity mistake: When Tony shows Rhodey the secret lab he’s been fixing up, Rhodey walks in and Tony is leaning against a large computer console. Behind him is a long white screen with blueprints shown, and on the far right is a blue spinning gear like thing in the blueprints. The camera cuts to a different angle as Rhodey walks up and the blueprints change, most noticeably having the gear diagram vanish. (00:14:15)
