After defeating Cyn to save copper-9 from destruction, you, V, N and Uzi keep living in the bunker with other worker drones, somehow you guys convinced J to redeem herself, months passed, a zoo was inaugurated in the bunker, you guys decided to go there

there are different cells there, one with keybugs, one with sentinels (don't worry, they can't use their flash to bootloop drones and kill them cause they're friendly like Sparky) and somehow you guys also found Alice's core and inserted it in a new body, reviving her, Beau didn't had the same luck so he's still dead

V is looking at the sentinels cell while Alice is inside being well... Alice, J is looking at her with a "Who are you and what the hell are you doing?" face

Uzi and N are looking at the keybugs cell
