AU Avengers: Budapest, 4 years ago

Natasha and Clint are tasked to intercept a dangerous package that is expected to be passing through Budapest’s famous Parliament Building. All hell breaks loose when Clint is made while attempting to retrieve the package. Natasha goes in, guns blazing, to save him and they flee the scene together while being chased by hundreds of parliament guards and policemen. In the end, they barely escape after blowing up half of District V and have to lay low overnight before S.H.I.E.L.D. can extract them. With adrenaline coursing through them, the two agents let their emotions take over and spend the night together. In the morning, they make their way to the extraction point, both questioning whether sleeping together was a good decision. They mutually decide that what happens in Budapest stays in Budapest and they go their separate ways.
