But does sneak attack work on him?Hypersmurf said:It can happen with a ranged attack into a grapple, too.
There's a chance you'll hit your ally who's grappling the BBEG. And since he's grappling, he's denied his Dex bonus...

The flavour text says
If a rogue can catch an opponent when he is unable to defend himself effectively from her attack, she can strike a vital spot for extra damage.
The rules text says
The rogue’s attack deals extra damage any time her target would be denied a Dexterity bonus to AC (whether the target actually has a Dexterity bonus or not), or when the rogue flanks her target.
