lol at number_6. No, there was no confirmation bias. Pre-2049 I was in the camp that Deckard was likely not a replicant. I have argued against that in the past. This movie closed the case for me.
1.) Deckard lives in solace, raising bees. This is identical to what we see at the beginning of the film, where the replicant is living in solace raising grub. No humans are ever seen farming/raising animals in this or the other film. Humans have lost humanity, replicants have become more human than human.
2.) Wallace is not rambling. Tyrell's legacy was just that: replicants can reproduce when engineered to do so. Wallace is not skilled as Tyrell was, he is an opportunist imposter.
3.) "I know whats real" - So thought K until he saw Joi's billboard and realized that it was all just what he wanted to feel, hear and see. Deckard never 'awakens' in that same manner that we see.
4.) Gaff sees K as a sheep (common, or follower), while Deckard was a unicorn (unique, special, different).
There was more, but thats all I feel like typing out at the moment.
Some other connections to Tyrell: his eyes were smashed by Roy Batty, he is reborn blind. Tyrell was killed before going to bed (sunset) and is renewed at dawn.
