Steve heroically dives on top of Tony to save him from falling equipment!  Tony heroically dives on top of Steve to save him from… touching a really hot shield!

Forever Man has this weird phoenix thing going.  Every time he dies, he’s reborn on the ashes of his old body with no memory of his previous life.  Except somehow he sneaked aboard a rocket and shot into the sun and melded with cosmic junk and that’s why he’s all burn-y and stuff.
