Subpanel install

I'll try to have this make sense.
I need to install a subpanel box by patio for spa. It will hold the GFI breaker.
Spa needs standard 3 wire setup.
So, 2 hots and a green ground to subpanel, then the same cutoff, then same to spa.
Now the part I don't know.
Subpanel has accommodation for one other breaker to use for whatever.
I plan on using it to feed electric to our BBQ island.
Standard outlet/light etc will use a neutral wire correct ??
Something I won't need for spa.
If I were to use the secondary breaker for an outlet on BBQ island, can I place the outlet neutral to the same bar that the spa is grounded to in subpanel ?
Make sense ?
Or will I need to run that 4th wire ( white neutral ) from my main box to the subpanel ?
Guess what I'm getting at is I have to run 3 wires from main panel to subpanel but do I need to run the 4th wire for neutral ? I'm asking because 3 wires are easier to fish than 4, plus I'd save the cost of wire.
I want it done correctly also.
I'm cheap, but not dumb

You need hot, hot, neutral, and ground supplied to the subpanel to accomplish that.

Neutral and ground can only be connected together at the service entrance. Nowhere else.
