[EX Q]: In the episode Deutschland 93 from the second season of Narcos Tata meets Murphy in the plane from Germany to Colombia and says to him: I hope you enjoyed Germany. It seems that the most plausible explanation is that she recognised him as a DEA agent and noticed that he spent all his time in Germany in the airport, just like she did. However I didn't notice any sign of sarcasm in her voice, she seemed to be completely emotionless when saying this. This leads to a second possibility that she simply remembered him from the flight to Germany and it was just some small talk. However if this is the case then I have really hard time understanding the purpose of adding this scene in the first place. Is it one of these two options or something else? What is the actual meaning of this scene?

[EX Q]: We all know that Reid has an eidetic memory. Nevertheless in the very first episode Extreme Aggressor he keeps scribbling into his notebook. Why does he need to take notes even if he will not forget anything? In later episodes I can not remember seeing him with a notebook.

[EX Q]: In The Fellowship of the Rings Galadriel gives each member of the fellowship a gift, many of these turn out to be critically useful in their quest: Frodo's light saves their life in Shelob's lair Sam's rope is used in emyn muil The broaches lead Aragorn to the Hobbits The cloaks hide them more than once There are two instances of foresight in the films, the first is Elrond who can see Arwen's future (and indeed Arwen herself). The other is Galadriel's mirror. Are these random gifts which may come in useful or are they specifically given for challenges she knows they will face?
