Quote #4
RACHAEL: I didn't know if I could play. I remember lessons. I don't know if it's me or Tyrell's niece.
Rachael's world is in tumult after Deckard tells her that she's a replicant. She's unsure whether the things she knows about herself are really things about her or about someone else. If her entire sense of self comes from Tyrell's niece's memories, it would almost be like she doesn't have any sense of self that she can genuinely call her own.
Quote #5
ROY: I've seen things you people wouldn't believe. Attack ships on fire off the shoulder of Orion. I've watched c-beams glitter in the dark near the Tannhäuser Gate. All those... moments will be lost in time, like tears...in rain. Time to die.
When Roy remembers the things that have happened to him in his life, he apparently isn't remembering any false or implanted memories. He's remembering his actual experiences as a soldier, grounding himself firmly in his true identity. Poignantly, he imagines death sweeping away the memories that make up that old identity as if they were "tears in rain." These memories die with him.
