After a mission went wrong you get sent to a different time where none of the Avengers knew who you were. Because of this you got caught by Hydra but luckily you got free it's been a few years when suddenly there's a knock on your door one afternoon. "Hello Athena?" You hear Tony's voice. You put on a jacket and gloves and a pair of socks, I pull out your gun just in case and open the door to the Tony from your time. "We built a time machine to bring you back. Everybody has missed you."
