Can we talk about the timing of the chorus during Nairobi's funeral?
I always felt Nairobi felt some romantic feelings for the Professor: from casually hitting on him, to protecting his plan in the Mint, to (after finding out he is in a serious and maybe even permanent relationship with Raquel) settling to having his baby.
In this lyrical metaphor, "Y ahora sé que nunca he sido tu princesa" (Now I know I've never been your princess) she knows he will never return her feelings.
"Que no es azul la sangre de mis venas" (and that the blood in MY veins isn't blue, metaphor for royal blood), she thinks that the Professor is out of her league then - focusing on Bogota - she now settles for someone that loves her, within her league.
On the day she dies, the focus turns to those who killed her literally (police in the tent delivering the shot) and figuratively (Raquel representing the death of her having a connection with the Professor)
"Me tumbaré sobre la arena y que me lleve lejos cuando suba, la marea". I'll lay in the sand and when the tide rises, I'll be taken away.
This line conveys a very "passive" mood. In her final moments, she is lying in the sand (in the bank) with no control of her fate. The tide rises (Gandia accumulates power) and takes her away. With the security detail as an extension of Gandia, the metaphor also extends to the "waves" literally taking her away from the "sand".
Line also conveys an active passivity from the speaker to where she says "i am not in control, i've been fucked over and over so i'll just lay here" basically a reflection on how the story unfolded her death. Nairobi, the character, has no control over how the creators will run her story on the show.
