The speaking Male Dren?

Two words "Inside You" to Elsa, sort of like saying, "Im having you so dont bother fighting me" in an almost exact cold unemotional way that Universals Frankenstein, when he learned to talk in "Bride of" and said "Love Dead, Hate Living" I think he said that to Dr Pretorius. Do you think this ability to speak came only with the latest physical conversion to male.

Female Dren was obviously intelligent, spelling out words and drawing pictures of her keepers. But it seems that the next stage of turning male invoked the human DNA that creates vocal chords for speech. Or maybe had she stayed female a little longer she may have spoken but I dont think so. I think the director wanted to shock us at the last minute with Drens words.

But given the females Drens advanced mental capacity if not emotional, I would think that male Dren would have had a lot to say or more to say at that moment when he raped Elsa. But then again what could Dren say? "Me Dren,You Sex Toy"?
