Lots of interesting behind the scene occurrences hours before the fight, during the fight itself, and immediately after the fight against Marquez.
Manny is really that religious? Up to the last moments in his dressing room, he was singing a church hymn. Kaso babaero and sugarol (but if you are a Peso-Billionaire with so much power, energy, charisma and popularity and temptations, who wouldn't be?)
Nacho has too much respect for Manny - humbly requesting through Roach for Manny's autograph on 3 personal items of his own friends right in the dressing room - even Roach couldn't believe the gesture.
The reason for the immediate reaction of Manny and Marquez at the final bell was made very clear. In a hindsight, it was actually a good thing for Manny that Roach was repeatedly telling him he was losing and that he must go for a knock-out (based on the video and the faces of Roach and Arriza, it would appear that the chief seconds honestly thought Manny was on the losing end), whilst really a bad tactical decision for Nacho to convince Marquez (too early) that he was winning enough.
The relay of instructions from Roach to Arriza to Buboy during the fight was interesting. I've always thought it was just Buboy shouting loudly his own instructions in Tagalog - yun pala, translated, passed and clarified from Roach through Arriza as the actions in the ring were going on. Roach (the boss) was constantly in full control pala.
Bonus: A footage of Roach's fight - he looked good and strong.
I suppose that was the series finale (for now).
