Roughly two years after the events of Iron Man 3, Trevor Slattery is an infamous icon. He’s also locked up in a high-security prison. Luckily, his new found profile has brought him celebrity and protection on the inside – and the actor has gladly agreed to an in-depth profile with a documentary filmmaker.
Trevor Slattery has been placed in Seagate Prison for his involvement with Aldrich Killian's War. Slattery is a celebrity there, and even has a "butler". He is being interviewed by Jackson Norriss, who is ostensibly creating a documentary about Slattery. During Norriss' final session with Slattery, Norriss is revealed to be a member of the Ten Rings, and attempts to kill Slattery. Norriss says that the real Mandarin is mad at Slattery for making a mockery of his name.
