quarantine 'em

Rick Deckard "retired" a human by mistake. He quit blade running and went to an offworld colony forever. That was in August 2019.

When the Nexus 6 escape happens, Holden nearly dies on the job and they need another plan. Gaff goes to Tyrell.

Gaff and Tyrell cobble together the idea of setting a replicant to catch a replicant. Tyrell loves the idea.

They contact Deckard and cajole him into releasing a template of his memories and physical appearance. The unicorn dream, though, is Gaff's

They wind the replicant Deckard up like a clockwork toy and put him at his favourite noodle bar. Bryant DOESN'T KNOW.

Tyrell builds replicant Deckard, at stupefying personal expense, pro bono. Gaff risks a death sentence with his complicity (???)
