Take me back to the night we met (слэш)

It's been three weeks since the battle with Thanos in Wakanda. Tony is still missing in space, Natasha has been trying to track down Clint, and Steve has just been trying to keep it together for everyone. How long can he keep it up, though? His soulmate is somewhere in the universe, but he knows Tony isn't dead. He can feel it. Still, they haven't spoken since Siberia, not once, though Tony has never been far from Steve's mind. He keeps seeing the ghosts of his team all over the Avengers Compound. Then Natasha tells him that a ship has arrived on the property - a ship that Rocket recognized as the Guardians' own.
