Key point: Yusuf Kama is Corvus Lestrange in disguise.
So, we established in the previous thread(link below) that Yusuf Kama is an animagus bird, specifically a Raven.

What I'm theorising now is that Yusuf Kama is actually Corvus Lestrange. Quite the opposite of what we were believing.
Let's support this theory now,
First read these sentences which Yusuf says to Credence and team.
KAMA
His servant, Irma Dugard, was a half-elf. Her magic was weak and therefore left no trace I could follow. I had only just discovered how you had escaped when I received news I never expected . . . The ship had gone down at sea . . . But you survived, didn’t you?(to CREDENCE)Somehow, someone had pulled you from the water!
So, you see, Yusuf received news that the ship with Corvus on it drowned and he assumed Corvus died in the incident. Which means, he thought he fulfilled the vow made to his father because Corvus was dead.
But if Corvus was really alive and someone saved him which Yusuf discovered like 26 years after the ship incident because of the rumours then shouldn't he have died during these years? Cuz ofcourse, he thought he fulfilled the vow but in reality he failed to fulfill the vow as Corvus was alive, right?
But Yusuf didn't die. Neither he seemed to realise this at all.
The only explanation is he is lying. I'm theorising he is not Yusuf at all. Yusuf Kama is dead because he failed to fulfill the vow. And this Yusuf Kama is actually Corvus Lestrange in disguise.
Supporting facts: He was an animagus bird, a Raven, which is the symbol of Lestrange Family.
But you would ask Corvus drowned in the sea in 1901, right?
But if the entire world is convinced that a child may somehow survive from being drowned then why not? But question is who saved him?
I'm guessing it was Grindelwald. Yes, I believe he too was in that ship. Afterall, it's said that after Ariana died, Grindelwald flee from the country. Guess what, he was fleeing to America and saved Corvus from dying.
He raised him and he is one of his acolytes or perhaps an equal. It's just how the Lestrange family started being dark afterall.
Moreover, when have you heard the word Raven in FB series?
First, it was the emblem of Lestrange family. And,
Second, a white Raven, was the emblem of Grindelwald as well as we can see in the messages sent by him to Paris in those black silks. Here's the exact extract:
QUEENIE reaches out to the nearest black banner, and an emblem of a white raven appears beneath her touch.
Huh! It shows the connection between two wizards. Both are fighting for the greater good.
It was all a plan of Grindelwald and Corvus to distract Newt and team from getting at Credence. As Grindelwald said in the beginning, the path has been laid and Credence has just to follow it.
