"Roy Batty" being Blade Runner and "Tyrell" being Ridley Scott, you see.
This doesn't end well for Tyrell/Ridley.
Ridley Scott has never been able to keep his hands off his seminal scifi masterwork Blade Runner (1982) always smudging the prints with his restless dirty fingers. Though we'll always love him for making it it's going to be the death of him (artistically) if he proceeds with the sequel/prequel/whatever. The creation will turn against the creator. It's an inevitability.
