[9S' first reaction to being given orders from A2 is a sour look, evident even with the visor concealing his eyes. His second is when 2B asks to join, and he turns to her, worry bubbling up in his reactivated vocals.]

[They were just reunited? The idea of her dying here... No. No, no no.]

[He gives A2 another look, aggravated at her for bringing it up, but also not about to squander an opportunity he'd been looking for.] Let's at least confirm A2's revival before we do anything. I don't know how much data I can get if they're going to slaughter her as fast as the natives say they are, but I can try.

[So, he'll just throw her to the wolves. It was her idea anyway.]
