While I'm sure it'll all end up in a singular way, I like the idea that your 'choice' with the Dwarves may resonate with 2B and 9S in some way. After all, one is dressed in White and one in Black, much like the androids themselves. One wants to rush in headfirst and discover as much and as quickly as possible, the other wants to exercise a bit more caution and figure things out first. I imagine the White one would rush things and assume 2B is the inherently good one and re-activate her, whereas the chap taking his time might figure out that 9S isn't as bad as may be implied by simply being a 'last boss' of the tier.

All I know is, at the conclusion, we have two de-activated androids and are on the hunt for a means to reactivate them, though I believe it was hinted we could only activate one (but that could be wrong). We saw a lot... LOT of dead androids in the factory and there's various mentions of very specific endings when referring to those and 9S.

Either way, as a non-Nier player, it has still been an enjoyable ride and I look forward to how it pans out - leaving all the actual speculation to the Nier-heads. Let's hope you all get a nice big surprise!
