Lucky you.

The Bestow Luck feat allows Humans the following:

You can also use your Inexplicable Luck ability to grant an ally that can see and hear its benefit as an immediate action.

That phrase is wholly unclear to me. Is it to be taken literally? The benefactor can be halfway across Golarion, as long as the intended recipient "can hear and see"? That seems rather odd. Unless "an ally that can (see and hear its benefit)" was meant. But "its benefit" cannot be heard or seen, it's just a bonus. And the feat doesn't say whether it's SU or EX, but either way the act of bestowing shouldn't be witnessable.

So is something missing? "an ally that can see and hear you" maybe? Or "an ally that you can see and hear"?

I think common sense indicates "you."

And I concur, but would it be "they see and hear you" or "you hear and see them"?

RAI, they need to see and hear you for you to grant them the benefits.
RAW, they simply need to not be blind nor dead, and you need to be able to choose them as a target. (Line of effect, or at least scrying, may be required.)

"that can see and hear its benefit" -> "that can see and hear you"
