Tony Stark is about ready to pull a big “I am Iron Man “ reveal when he has a heart attack. To help him, people rip open his shirt and find his armored pacemaker. So newspapers begin to figure out that Tony and Iron Man are never in the same place at the same time.
Happy Hogan throws some armor on to protect his boss’ secret, and Mandarin is convinced Happy is the hero, so he nabs Happy Iron Man.
This means his armor is gone and Tony has to make a new one to fight Mandarin.
And this time, it’s the version we’ll be seeing for a long time.
Oh, and, in case you were wondering, he rescues Happy.
This is weird.
