F - Victor and the monster's relationship, although it is extremely violent and full of hate, is necessary for both to survive. I think it shows that inextricable bond between creation/creator, and its also Shelley exploring the destructive end if we take science to far and we're unable to fulfil that relationship it can end in serious consequences (i.e. both dying)
BR - its more of a plot thing, but it pretty much suggests that Deckard is a replicant. The origami thing represents something from his dreams, stuff humans are "supposed" to have naturally, but since Gaff (presumably) has access to these dreams, it suggests that these memories have been implanted in Deckard, much like how replicants have subjective human stuff implanted within them. (I wouldn't use this as part of my essay..its just a fun thing to talk about)
