Iron Forged in Fire: Part One - S1-E1
Revealing mistake: After Howard’s death, Tony and Rhodey are trying to get back into Stark International. A guard is giving them a hard time and he is wearing some sort of shades and head piece.

The glass in one spot is flickering around like TV static. (00:07:10)
