Ah, but I thought Deckard said that he was gone before the kid was even born. That he had never seen the kid. If he was with Rachel, that explains how he carved the tree.
Nevertheless, they found where the horse was carved because of the Vegas radiation. So Deckard had to carve it when he was already hiding in Vegas while Rachel, from the photo, was obviously living at and giving birth dying at the farm (with the tree in that photo of her). He also said that after the blackout, he couldn’t find any of them and obviously, while he was in hiding he had no connection with any other replicants. Even they didn’t know where he was since they had to use the tracker planted on K to find the casino.
That’s where I was confused. Once Deckard is in Vegas, he shouldn’t have had any contact with anyone related to the kid, but he carved a horse there that somehow got to her. However honestly I think a lot the background was simply there to provide a reason why people who should know tge answers to the mystery don’t have them.
My disinterest watching the movie had more to do with the length given to the set up of the story didn’t really have powerful payoffs. Honestly, I didn’t really care about the daughter even though it was a nice scene or thought that it would mean much to the replicants’ cause. I mean, it’s no miracle if Tyrell designed a replicant to have a kid - it’s just engineering. Whether or not they can give birth doesn’t make them any less human, and honestly unless they work with Wallace, none of them can or will ever give birth anyway.
What’s their practical endgame strategy? The whole late introduction of the replicant underground didn’t seem that well-thought out, but someone had to get K back into the story. It makes sense in the story, but it didn’t really seem that important or lead to a clear conclusion. Honestly, it almost felt like this “happy ending” was tacked on just to go out with something resembling an upbeat emotional payoff.
Sorta like the Shining helicopter shots with Deckard flying away with Rachel at the end of the theatrical cut when the much more ambiguous final cut elevator door closing fits the tone of the story much better.
I can see why people like the new movie, but I never quite bought the story as much as I appreciated the world of the movie.
