of Blade Runner, has suggested in interviews that Deckard may be a Nexus-7 model, which possesses no superhuman strength or intelligence but does have neurological features that complete the illusion of humanity. Sammon also suggests that Nexus-7 replicants may not have a set lifespan (i.e., they could be immortal, ruling out the lifespan as a determining trait). He goes on to propose that Scott thought it would be more provocative to imply that Deckard is a replicant. In-universe evidence In Do Androids Dream of Electric Sheep?, Deckard was subjected to the Voight-Kampff test and passed, marking as a human, though Rachael's near-passing the test casts doubt on its infallibility. He collects photographs, yet has no obvious family beyond a reference to his ex-wife (who called him a "cold fish"). The film's Supervising Editor Terry Rawlings remembers that Scott "purposefully put Harrison in the background of the shot, and slightly out of focus, so that you'd only notice his eyes were glowing if you were paying attention...Ridley himself may have definitely felt that Deckard is a replicant, but still, by the end of the picture, he intended to leave it up to the viewer." The sequel, Blade Runner 2049, revisited the question while leaving the answer deliberately ambiguous. The film reveals that Deckard was able to conceive a child with Rachael, and this was possible because she was an experimental prototype (designated Nexus-7), the first and only attempt to design a replicant model capable of procreation. Niander Wallace, CEO of the company that produced replicants, captures Deckard and muses that his falling in love with Rachael seemed too perfect, suggesting that Deckard was designed to fall in love with Rachael as part of Tyrell's experiment to develop replicants that can procreate, but with Tyrell dead and the records destroyed, he will never know.
