I have just seen the movie and read the synopsis at Wikipedia but I still don't know whether K is Rachael and Deckard's son and what the deal with the twins was. Today I had a three-hour chess game and my mind is tired.
Could someone please explain this son/twins/etc. deal, please?
K is the (boy) clone of Deckard's daughter, created as a decoy to throw-off anyone coming to look for her in the future. That's why K has some of her memories, and that's why she was crying when he went to see her. She realized who he was, but couldn't tell him because that would put her in harm's way.
Wow. I saw a different movie. Or missed things. SPOILERS SPOILERS SPOILERS BE HERE
What I saw explained inside the movie was: K (and us) were lead to believe HE was THE son, for a little while, and a DAUGHTER had died. But, Deckard explains to K that he taught them how to switch records around.... THEREFORE, the real son had died, but the daughter lived on - NOT the son.
K had memories about the hidden horse, as many did, because SHE (daughter) was a memory maker working for Wallace, THUS implanting many of the same memories into most of them, leading to.....
Many of the replicants think THEY were the son/daughter - this was explained in the scene where all the replicants are gathered and they try to convince K to work for their cause.
This is even more powerful, because we realise that K's existential crisis and very human struggle for meaning is simply the result of the idea that he was born... so, in that sense what has kept K from being more human during his life so far is the simple idea that he is a non-human "replicant" and therefore somehow not a real boy/man...
So to recap. K is not Dekard's son. K is not human. But K does end up learning that as a replicant he is much more human that he was lead to believe, as he wants and feels the things that natural born humans do...
It's brilliant as we are allowed to go on this journey with him as well as to contemplate it again when his (and our) misconception is revealed... so good...
The daughter of Deckard happens to be in charge of creating most if not all the memories of all the replicants wallander makes. They hire her because she is the best at making up memories.
But as they explain in the movie, all artists leave a little bit of them in their work, which means that as much as she makes memories up, sometimes real stuff will also make it through the implants of the replicants, so many replicants walking around in the world have memories in their head that are actually hers in reality, this isn't normally an issue, it's not like replicants start chatting up between each other remembering the past, after all, they know their memories are implants as well.
When K sees the numbers and then triggers a memory from when he was a kid, he realizes this memory may not be made up and actually real, the thing here is that K, just like the audience, start to believe (with hope) that he is Deckard's son but in reality nowhere in the movie do they say this. Just like in the first blade runner, Raechel's memories were actually Tyrel's niece, so it was more likely that K was implanted with the memories of the real son/daughter than actually him being the actual son of Deckard.
But then he starts digging and find that apparently there were two of them and that the daughter died and the son lived, this was just a decoy to keep people looking for someone else other than the daughter but we as an audience (just as K as someone looking for a reason to exist) want to believe deep inside that he really is deckard's son.
At the end we get hit with the harsh reality that "they all want to be the one" obviously, they all want to be the real replicant son/daughter of a replicant, just like K.
But for K, even if just a little while, Deckard was his dad. It's a very powerful moment when Deckard asks K "who am I to you?"
You know K was thinking "for a little while I thought you were my dad" but he takes him to his real daughter.
Ryan played the part exactly as he should've: a cold, powerful replikant who only has feelings for his AI. Notice the only time he shows any emotion throughout the film is when everything he thought he knew about himself was being challenged. That's because what was happening (or what he thought) was beyond the scope of his design. Humans call it cognitive dissonance - when things aren't adding up, your brain (mind) tries to create something to put you at ease.
From my understanding of the film, there were no twins. The whole idea of creating matching DNA records was concocted by Deckard in order to further confuse and obscure anyone trying to find his daughter.
This fits in with the group of rebel replicants almost mocking K for thinking that he was himself 'born', and stating that they all have wished for that to be true about themselves too.
K is merely a replicant assigned to be a Bladerunner. Since Wallace does not generally make one replicant model at a time (an exception was the not-green-eyed Rachel), who did not last long, there were likely thousands of replicants who looked like K and had the implanted memory of the horse and hiding it from the boys.
As for the other replicants that were forming an army, I got the sense that they were all aging Nexus 8s, some of whom were part of Sapper Morten's crew, not misguided newer models who thought they were the son or daughter of Deckard and Rachel. If you think about it, K only uncovered that through extensive investigation.
Which makes me wonder if Wallace and Luv knew there was a child before K started the investigation? If they did, with their virtually infinite money and access (ala walking into LAPD HQ TWICE and murdering cops), they would have ran it down.
I don't think they did, recall Luv killing all of the nomads and telling K to get up and do his effing job "find the child."
