Indeed, there is no confirmation yet.
But it fits in so well, MC's presence as a deterrent for 'the Alliance', Mother's broken engagement, the burned picture of the Serpents, Mr. Serpents hatred for MC's father.
I hope its true it will fit in so well.
100% with you on that it woud fit like a glove. You even left the biggest one out, when Nazazi calls Nero's father a whore right to his face, so his "serpent whore" description is a HUGE arrow pointing at it being the MC's dad.
We know that the MC's father was not on the picture we find in Cordia's desk, right ? So he wasn't one of the OG Serpents, but all we got now is "all those years ago" so he would have to have been a serpent sometime between the OG Serpents and the split of those OG Serpents.
Or, and this is what I think makes way more sense, that "Serpent" has 2 meanings, one used by the Deluca family as a de facto rank, just like apparently the Sterling rank from the Silverinos. And then a somewhat more descriptive meaning that others outside the Deluca Family use to describe a group of people that fought together way back when they had their big war. The MC's dad could've have been a part of that group, but with his own ambitions of starting ? or taking over ? his own family so he never joined the Deluca Family but instead did his Silverino thing, thus never becoming a "Serpent" in the Deluca way, but to others he was one of them.
However there is one thing that bothers me with all of it and thats what Hope has repeated to us over and over again. Cordia, Pervez Kaskar and now Nazizi all state that family and specifically ones children, mean everything and no matter what, you protect them and have their back, and yet Nero says "The MC has some use for our family, when we are done with him, you can do with him whatever you want." Now to me that doesn't sound like a very protective father and as far as we were told, he left the MC when he was 10 and never had any contact since so I dont see any way how he could suddenly hate his son or be so totally indifferent to his well being.
