Haunt me in my sleep
Okay, so you can walk on water. Big friggin' woop.
Nah, Zeph, let's be real- you're as jealous as a crocodile, watching her with a bit of awe as she strides atop the surface. "Neat trick, kid," you remark with a whistle, bobbing a little deeper into the water with your head still aloft. "Gonna' hafta teach me that one after we're done here, eh?" You wiggle tour eyebrows playfully, but before she can respond you've taken a breath and disappeared beneath the water, your salt and pepper hair forming a little whirlpool before being devoured by foam.
Your plan is to keep below long enough to tempt her further in (on?), into arm reach. You can hold your breath for nearly three minutes, and though it stings like a bitch, you've kept your eyes open underwater often enough to be able to withstand the pain.
Of course, if she doesn't come close enough to grab her by the ankle, you'll have to just rise back up - with a mouthful of water to spit up in her direction, and two broad hands ready to splash her and hopefully cause a good level of surprise.
