Where is the high voltage return path in a plasma ball?

It's right through your finger down through the left leg into the big
toe and off to ground via your shoe.

But the HV generator isn't grounded. It needs to get from me back to
that somehow. I looked inside one and only one wire leads from it, to
the centre of the sphere. Where is the other one?

Research "capacitive"

Oh, you mean because the frequency is so high, the current is tiny, so
you don't need a return, it just comes back in the other half of the cycle?
