I have been quite tempted to try and create Doctor Who Target style prose novels for these episodes to expand them more, and this one especially has some fun concepts.
Rhodes is the character whose fate I am most concerned about. Without Tony or Natasha he's likely to have been trapped in the War Machine armour.
Also Peter will be dead. Remember he's the boy in the Iron Man toy helmet Tony saved at the EXPO. Ergo no Spider-Man.
