Undo

In an attempt to steal information from Tony Stark's brain, the villains of the week accidentally unlock the memories Tony lost after deleting his mind. Now he remembers everything, but it's all fresh and raw and without logical order. Worst of all, he remembers Steve dying, but has no recollection of him coming back. As a result, seeing Steve just makes everything worse, and the memories Tony has of their recent relationship make no sense and drive him crazy.
Consequently, Steve gets banned from seeing Tony until he gets better and it's Rhodey who gets to be there for his friend while Tony struggles not to fall apart. Steve, meanwhile, gets to deal with the media, who have just now learned of Captain America and Iron Man's romantic involvement. It is not something he excels at.
And then things get worse.
