[Keith tries not to mind the time between them. And really, he doesn't want to make things harder for Shiro. It seems unfair to burden him with the knowledge that he's about to die in the next moments waiting for him back home. That another him appears that is him and isn't him at the same time. And that he is alive again after it all. It's a lot.

So he considers the questions Shiro is asking, balling up the wrapper to his own finished burrito before wrapping his hands around his coffee cup once more. A deep breath and he looks up at Shiro.]

Your arm. [He begins. And it's not this current arm, but one that seems identical, so the concern is there. But that also makes it true the way he phrases it next, not "your arm" not "controls you" but,] We've seen Haggar use one just like it to control someone's mind entirely, turn them against their friends and allies.

[Maybe it was because the other Shiro was a created clone that it was possible. Maybe the prosthetic itself isn't enough, but they don't know for sure. It still makes Keith wary. He will not lose Shiro again. Not here, not anywhere.] She's not here, so it's probably a non-issue. But we've also got a bunch of nanites running around in our bodies alerady, and I don't know if that means someone else could gain access.
