Okay, so the problem with the grenade is quickly going to be getting far enough away to even get it out. He'd hoped to clear the little spirits but they're persistent, and he's clumsy. Even at his most determined there's a risk he'll utterly fail and this is one of those times, as he throws the small spirit and then topples heavily to the ground at the shift in weight and the creatures grappling his legs.

So that's not great. But he fights to at least get up onto his hands and knees quickly, trying to keep Mary out of their reach, then hears the whistle of a rock go flying past his ear. It takes all his strength just to force little hands off his arms and stand back up, and he's quite strong, too. He underestimated these spirits from the beginning.

"Let go," he snarls as he tries to kick the spirits off and keep moving, and this time stoops to grab one by the hands and try to swing it as his own sort of club at its fellow little rock people. There's another whoosh of movement and one of those sharpened sticks plunges javelin-like into his back, though the layers of cold-weather clothing keep it from driving too deep. He'll ignore it for now - not much else he can do, occupied as he is. There will probably be more, too. Someone his size isn't exactly a hard target to hit.
