I get this image in my head of Clint saying something to the effect of "Hey Nat, what's an extraction plan?"
"Hell if I know," Nat answering with a smirk.

AhhHHHHH I can totally see that happening! :D

And since it's Clint he would ask during the most inopportune moment, like when they were surrounded by the bad guys or running away from the building that's on fire with everyone chasing after them, lol.
