If we had had even a slight mention of Danny in the show, I would think he was a possibility, but we haven't. I was really hoping he was involved with the benefactor story line. And I am pretty sure Jeff said something about "he's in college now!" Or something similar. Per the rules of villain reveals you have to at least mention in the first act, see them in the second, and reveal in the third. We haven't gotten either.

Now, someone, however unlikely it may be, that DOES fit the rules would be Theo's sister. I mean...you have to remove BOTH hearts to do a transplant. Why waste the opportunity for two experiments? Not sure I believe this myself, but it does technically fit.

You can't discount Mason based in his size. The beast is bigger than literally all humans on this show. The only thing that's ever come close to it in size is Voltron Twins.
