minor questions have been bugging me
why did Luv have tears when she killed the police chief
My interpretation is she has no idea how to control any of the emotions that she is feeling while lying and murdering, so everything – exhilaration, terror, remorse, pleasure – mixed together is coming out at once.
and what was the point of wallace slicing open the uterus of the new replicant ready for inspection while monologuing his frustration at not having the key.
He was trying to make a new model that could reproduce but knew it was again a failure. That sets up his need to procure Rachel or her child.
what was the purpose of sticking a chip on his neck and the elaborate case of other chips, he couldn't wirelessly get information inside his own office?
He's blind. The neck chip allowed him to see diagnose the replicant.
