Tristran starts to laugh. There is a possibility he is laughing at her, with some of her deep blue skirts floating about her like a balloon while some are submerged under water.

Then, staring at her for a moment, he lets out a sigh.

"Oh, why not."

Pulling off his boots and his coat this time, Tristran dumps them off to the side and jumps into the water, creating quite a splash.

If her hair had been at least partially dry before, Yvaine should now be quite re-soaked again.
