Forget-Me-Not

Jocelyn was serving, and she and her opponent had played two points when a disagreement occurred. Jocelyn had won the second point, but neither player could remember who won the first point. They both agreed that they needed to replay the first point.

What should the score be?

They should go back to 0-0.

They should go back to 15-0 since Jocelyn definitely won the second point.

They should replay the first point and give Jocelyn the second point.

I’m not sure.
