OK this is just full on crazy people stuff now . <| sep |> Why does alpha have it easier ? When I was there alpha never got out early because all the chiefs were still there , Bravo hardly ever stayed there for the entire time . Has it changed ? <| sep |> Love being downvoted for a polite dissent not saying it was you . I still hold that they ' re unrelated . Abbot is tapping the glass because he ' s trying to tell them there ' s a bomb . Louise taps the glass ask him to come inside . I don ' t see any correlation . But for the sake of argument , let ' s say you ' re right . What ' s the point ? It doesn ' t add to the movie . The scene is in the final montage showing us that they ' re together . There isn ' t any reason that it ' s a callback to the scene on the ship . It serves no purpose and doesn ' t enhance the moment at all . The focus is on the two of them , not tapping glass . Sometimes tapping on the glass is tapping on the glass
