The scene played like this between Adi and the security officer
he said to Adi - you are a reporter and you should know better - there is no proof...you are telling me in spite of so much security at the airport some one can be smuggled over without their marzi?
its a direct parallel to how Adi was molested.
Also the way BBSB pleaded with the security guy to ask him to stop the plane but he did not...that also should tell him how Imlie would have felt when she tried to tell him the truth and he did not listen
Imlie story is tacky these days - but their attention to dialogues, foreshadowing, symbolism and parallelism - is what keeps the discerning viewer hooked to this show. At least that's what I tell myself when the tracks get super contrived and characterization is killed. :)
That's why the more times you watch you start seeing the nuances and appreciating the episode more
