[Boone sure doesn't mean to be offensive. He's just trying to make sure nobody else gets hurt, and isn't really thinking about whether or not Tuco understands that or not. He watches Tuco carefully upon hearing the whimper, then gives Belloq a meaningful look before turning away. He's going to trust Belloq to keep Tuco from going straight for the chest this time.]

Is it safe?

[He's going to assume no, at least until Niko can confirm that it is.]
