Saves Harry from kelpies

One of my feet flew out from underneath me. I went down, flailing my arms and legs, dimly aware that one of the kelpies had somehow gotten a limb tangled around my ankle. I got dragged to the back of the boat in a quick series of painful jerks and impacts, and had just enough time to realize that the boat was about to surge right out from under me, leaving me in the drink. Then it would just be a question of what killed me first-the icy water or the strangling embrace of the company within it.
Then there was a flash of scarlet and white, a whistle and a hissing sound, and a lance of fire on one of my feet. I went into free fall and bounced into the rear wall of the boat, then to the floor. Icy rain and freezing water splashed up against me, viciously cold. I looked down to find a strand of fibrous weed curling and blackening as it fell from my bleeding ankle. Sanya reached down and plucked the remains clear of my leg before tossing it over the rear of the boat and back into the water. My ankle was bleeding, my blood black in the green chemical light. More black stained the tip of Esperacchius.
I clutched at my ankle, hissing in pain. "Dammit, Sanya!"
Sanya peered out at the darkness behind the boat and then down at my leg. "Ah. Oops."
