This is a short fic; I think it was only one chapter. Wanda is trying to change history, maybe?But every time she does something she makes it worse. She and Tony are on an asteroid (?) watching the destruction of Earth. Tony is in his suit, which may have been partly destroyed. He's watching as Wanda makes everything worse, and is crying (?) and pretty much headed to a mental breakdown. I don't know how much vaguer I can be!
