1. This is clearly a confusing question for the ghosts to answer. Assuming they're using their candle setup, the candles wink out all at once and then on again, then off and on again. Finally they'll settle on "yes," although it's unclear in response to what, and "too late." The nearby walkies fill with uncertain static.

2. More wavering, a lingering silence of undisturbed flame, and then "desperate" with no further clarification.

3. Immediate answers. Yes, strongly, and then "go" and then "heart" and "mouth." The candles will flicker between heart and mouth.

When Pal is with Dax, an answer will take a while to manifest, but Dax's walkie will erupt into inconstant static full of incoherent voices.
