Is there anyone who is not dead but looks to be heading in that direction.

...She's going to just. Completely ignore butt guy. He can deal with that on his own and that's probably not a "healing powers" issue anyway.

Nope, that'd fall under teekay.

Some stabbed people may be mid-dying.

Can she cause not that.

Yes! An ER nurse notices the pink glow, blinks groggily at it, and does not attribute it to Emily.

Meh, even if she did get caught, it wouldn't be worth someone's life not to. She heals everyone she can find who looks like they might otherwise die.

That's a lot of people, in a hospital on a busy day. Her gem dims noticeably.

Yeah she's gonna go find and kill that witch now.

Dowsing works as described.

Okay. So finding the witch shouldn't be hard. And getting inside isn't that difficult either.

Now she is in a sort of... evil kitchen. There's cookware and garlic and curing meat hanging down from a vaguely-defined ceiling, heaps of ice cubes in which boxes of popsicles and bags of blueberries nestle, a spice cupboard twice her height over there full of broken jars and too many mingled smells. The door ahead might lead to a giant oven; the circle under her feet might be an induction burner; there are wheels of cheese and loaves of bread she'd need her greatsword to slice. Knee-high saltshakers with stick limbs march to and fro carrying cleavers and carving knives.

She summons her greatsword.

A saltshaker takes a swipe at her ankle.

Dodge. Stab.

It shatters. The other shakers don't react.

That's nice. She'll ignore them as long as they ignore her.

They mostly do. Now and then one takes a stab.

The stab-happy ones get stabbed right back.

She gets closer to the center.

She crosses gas-flame-lined oven racks and goes through a walk-in freezer and finally winds up in a food processor with enough room to puree a house. The blade spins slowly.

The witch is a sort of warped gingerbread person frosted bloodred, with a blowtorch in one hand and a steak knife in the other. She moves fast, leaping from the blade of the food processor and going for Emily.

Emily gets her greatsword between them and summons another behind the witch to backstab it with.

The witch cartwheels out of the way and aims her torch. It's deafening.

Well fortunately she isn't navigating by sound. She drops to the floor beneath the flame and tries to summon enough greatswords to telekinetically cage the thing.

Crumbs scrape off its limbs. The torch can aim through the gaps between swords.

Well so can more swords.

Gingerbread fragments rain to the floor.

The labyrinth shimmers out of existence. There's a seed.

She picks it up. Is clearing the dinge from her gem as intuitive as everything else she's tried?
