Dive in

I had this weird dream last night that involved water and scuba diving and really cool steampunk kinda stuff.  One part of it was Willow, standing on an indoor platform with her hands held up above her head like a diver.  A diving board diver, not a scuba diver.  There was a man with a clipboard who told her to hold still, and then he made a calculation based on the angle of her pressed-together hands and drew an X on the floor and said that if she dove from that spot she'd, go up seven feet in the air and land right here.
