Here is how the Avengers and Weekenders got to Lagos, Nigeria to hunt Crossbones and Wanda's mistake goes in Weekenders and Captain America: Civil War.
(LAGOS: PRESENT DAY)
(we see Wanda putting sugar in her tea and stir it)
Steve Rogers:(on earpiece) Alright, what do you see?
Wanda Maximoff: Standard beat cops. Small station. Quiet street. It's a good target.
Sunset Shimmer: No idea where they could be hiding. But why the Institution?
Steve Rogers: There's and ATM in the south corner, which means...
Tino Tonitini: Cameras.
Steve Rogers: Both cross streets one way?
Wanda Maximoff: So compromise the escape routes.
Discord: Means our guy doesn't care about being seen. He isn't afraid to make a mess on the way out. You see that ranger half way up the block?
Wanda Maximoff: You mean the red one? It's cute.
Natasha Romanoff: It's also bullet proof, which means private security, which means more guns, which means more headaches for somebody, probably us.
Sam Wilson:(on roof) Anybody ever tell you, you're a little paranoid?
Natasha Romanoff: Not to my face. Why, did you hear something?
Tish: Eyes on the prize, please.
Steve Rogers: Tish is right, folks. It's the best lead we've had on Rumlow in 6 months. I don't want to lose him.
Sam Wilson: If he sees us coming that won't be a problem, he kinda hates us.
Choppy: He's got a point.
