headcanons.
While Pedro Alonso is only 4 years older than Álvaro Morte, I think it is possible that the age difference between Andrés and Sergio is a bit bigger, considering how they behave around each other. Maybe 7-9 years?
Álvaro Morte said that his headcanon is that the two of them share the same father, but I would agree with this post a tiny bit more. Because why would they have a different surname? Also, why would Andrés tell Sergio “he was your father after all” when they were burning the photos? It would be, of course, possible that Andrés was adopted by his step-father etc. but why would they be so close? It is not very probable, two brothers, who spent their childhood with different families would be that close, non? My guess would be, Andrés has a different father whose surname he carries and he was brought up by Sergio´s father?
Andrés had to steal money for his little father´s treatment when his (step)father got killed. He also took Sergio to Russia. (I like that Álvaro Morte´s headcanon)
I still can´t decide whether Berlín´s five wives was a mere fantasy or whether he actually really was married five times and had children :D.
His grandfather was Italian. (It was said in the final episode of season 1 that the Resistance´s song “Bella Ciao” was taught by the brothers´ grandfather who was a Resistance fighter during the WWII. If we take this into consideration, Berlín´s surname sounds quite Italian... and now I´m back in the maze with their family relations :D)
Lots of people think that the sick child in the hospital didn´t necessarily have to be El Professor with which I disagree because diseases like Berlín´s are usually discovered at an older age than during childhood.
Berlín has the generative disease, took part in the experimental Retoxil treatment and had a couple of months to live. (I believe the maximum was 14).
His biggest robbery was stealing jewellery from Champs Élysées.
He kind of likes Nairobi. (I need to write this. They are my darlings! Everyone is but these two).
He is a megalomaniac and an egoist with a wonderful sense of humour who probably secretly reads The Alchymist by Coelho over and over again.
