Freydis swim good

There was a splash from above, and then Freydis arrived, the lean woman cutting through the water with nearly as much grace as Lara. She swooped down, kicking smoothly, headed for the knife at the back of the thing’s head. Tentacles threatened her, but the Winter Lady flicked her wrist and half a dozen bull sharks rushed in, jaws ripping and tearing.
Freydis reached the knife, seized it in one hand, ripped the pin out of a freaking grenade that she’d been holding, and shoved it in the same hole where I had put the flare. I could see the outline of her fingers and hand through the creature’s flesh in the illumination of the still-burning magnesium.
I started kicking for the surface as fast as I could. I wasn’t worried about shrapnel from the grenade, but water is a noncompressible liquid. The blast would carry through it excellently, causing far more damage than the same explosion in open air. If anyone was too close to it, they’d get their lungs pancaked, and I had no way of knowing exactly how far the force of it would carry.
Freydis pushed off the thing contemptuously with her legs and had caught me in an embarrassingly short amount of time. I looked back to see Molly gripping the dorsal fin of the largest bull shark, rushing away from the wounded monster. Lara held on to Molly’s ankles, dressed in the shreds of her underwear now, her pale skin covered in cuts and circular sucker marks, oozing slightly-too-pale blood in little streamers, and we all ran like the last fighters at the end of Star Wars.
