P.S. I talked about Wendy in reference to her abilities as Ripley 8 in the first episodes, I think I was not mistaken in the end but they still haven't given any explanations on the subject. But she has xenomorph DNA inside her.
Arthur.
They also really didn't offer any logical explanation as why Wendy has EM superpowers while none of the other childs have. Wendy already had the ability to 'hear' xenos even before humanity's first contact with them, so the "contamination during her fight" theory is also very improbable.
That aside, Wendy is the real monster of the show. Her motivations are inherently selfish & evil. First, she uses her superpowers to deny her brother the transfer he wanted. Then, feeling guilty, she convinces Kavalier to send all (not only her) of the unprepared children to a potential danger zone. The first thing she takes for a rescue mission is a makeshift blade (which makes absolutely no sense unless she had read the script... For what do you want a blade for, psycho?).
Disobeying especific orders, and her contract with prodigy, she reveals her brother its true nature, reopening his psychological wounds and moral distress. After rescuing her brother, she has no problems with her brother's excised lung being used to gestate the very same creature that almost killed them both... Not to mention having absolutely no problems with the biological experiments on the other dangerous creatures. She had full access to the labs, seen what was being cooked there, and was not only happy with it, but eager to participate in the experiments. Again, no problem in nurturing a dangerous/lethal organism.
Also, while she knew some kids were resented about not upholding her contract with prodigy, and having direct contact with her sibling (while the other kids severed all personal connections)... She could not care less. Up to here, she was perfectly fine with all of this... But the moment they deleted last week from Nib's memory, trying to cure/alleviate her obvious psychotic tendencies... Wendy goes full
"OMG What have these Monsters done???!!! I'm outta here!!!... For which he releases a lethal organism as a distraction, perfectly knowing it would cause the death of innocent people. Not only that, but she directly controls it to kill, which makes her a de-facto murderer.
She also tried to convince the other kids to leave the island with her, ultimately only the psychotic one agreeing with her. Finally, when the psychotic one brutally kills at cold blood, wendy takes her side, and if not by her brother's intervention, she would have killed (or would have let die) everyone at the docks (she may probably still do it anyways).
In all seriousness, she's one of the most evil characters I've ever seen, portrayed as 'heroine', in the last decades. The real monster.
