On September 1, 1998, an 18-year-old witch or wizard is thrown back 21 years by a malfunctioning Time-Turner, landing on Platform 9¾ on the first day of the Marauders’ seventh year (1977). Trapped in the past with full knowledge of the coming war and its tragedies, they must pose as a transfer student, navigate friendships (and possible romance) with James, Sirius, Remus, Lily and others, while struggling not to break the timeline in their desperate search for a way home. A tale of survivor’s guilt, found family, and the unbearable weight of the future.
After Bucky is freed from his brainwashing/programming for good, he calls Steve with a request. Help him save the girl he heard screaming in her cell for decades that got left behind when he escaped. He doesn't know what she looks like. Doesn't know her name. Just that he needs to save her.
Two years ago, Steve left you waiting for him at a hotel in Germany during the confrontation at Leipzig-Halle Airport. He promised he'd come back. He didn't. No calls. No texts. Until now.
POST-ENDGAME AU: You're a former SVR agent turned traitor to your homeland with a bounty on your head turned probationary Avenger. Bucky hates you because of what you were. An OP in the middle of the countries that want you dead force you to work side by side with him as a "married couple".
