Page 29 contains very significant color symbolism. The difference between the red lights of the secret facility and the cool outdoor setting makes the facility seem womb-like. WE3 are being born from this place; they have been recreated and built. They leave the facility with different minds and bodies than when they first entered it. We can see this clearly when Bandit finds out his name, or when he discovers that the suits are ‘coats’ and not skin.
It seems ironic that the womb would be considered someplace safe, since had they stayed the animals would have been decommissioned. However, perhaps this is reminiscent instead of birth: they have come to a point where they must leave and find their own way in the world—be born again into the ‘regular’ animals adopted at the end by the man.
