It's an interesting reaction to see, and A2 takes it in. 6O hasn't done anything to deserve this herself, but there's still a good amount of vindication there anyway. With 2B, A2 has respect for her. For 9S, a promise to keep.

6O has neither of those things going for her. So A2 is standoffish.

And yet, the operator still offers maintenance to her, and A2's eyes narrow. The only thing she can think of is it being some kind of trap.

I can do my own maintenance.
