Re: Captain America 2: The Winter Soldier
They could have just included a five second quote in that little newsreel montage at the end about "the last of the alien invaders being disposed" or something to that effect. Or just have them turn tail and flee up into space all at once, "the last of the bogies are bugging out and going home! Yeah!" Seriously. A few seconds is all they needed to deal with the remaining Chitauri without them going all Phantom Menace.
