"It was all a lie!"

- yeah, she wouldn't be okay either.

"I know." She ought to have good words, but she doesn't, not now. All she has is sincerity. "I'm sorry."

"A noble lie, brother," says Sesshomaru, casually coming out of absolutely nowhere to pick Inuyasha up by his neck and lift him over the swamp (totally ignoring Kagome, Jaken, and the Un-Mother). "For now I know where my father's grave lies."

A faint, superior smile. "How could Sesshomaru have been so blind?"

"What are you babbling -" Inuyasha's attempts to rip his brother's hand off his neck are not all that successful!

And that's when Sesshomaru sticks two fingers in Inuyasha's right eye and rips the pupil out.

There is some piece of her that distantly feels like she ought to do something, ought to attack him like she attacked Jaken and the Un-Mother. Some nearby piece can see the complete effortlessness with which he lifts Inuyasha, the way that Inuyasha's struggling has no effect at all, and she knows - to strike him would be like trying to demolish a metal statue with a toothpick.

The rest of her mind is silently screaming, flailing, pleading with nothing for it not to end this way.

She watches, momentarily frozen in horror.

Sesshomaru will drop Inuyasha and study the - bloody black pearl that he still holds dantily between two fingers. "I searched the earth, and did not find it - my father's true resting place." His expression twists into an ironic smile. "'A place that cannot be seen, even by its own guardian'... it must have taken him exceptionally powerful magic to conjure it into your eye.' How much he feared the desecration of his corpse..."

"You did this - faked my mother's resurrection with that witch - for a marble?"

(His right eye is still closed and bleeding, and whatever control he may have had over his temper is shot.)

Yeah, Sesshomaru's more interested in the marble than answering his little brother.

okay sesshomaru dies now

"I'm rather busy," Sesshomaru says, dodging effortlessly, "so if you intend to delay me I will have to just kill you."

dies now

And Sesshomaru lines up a shot - 

- And the Un-Mother blocks it.

She does not survive doing so. When Sesshomaru's poisonous claw hits her she - 

- falls apart.

Aren't they working together? Wasn't she just trying to eat Inuyasha a minute ago??

"Why would - ?"

Myoga, apparently, has hidden himself in her hair right now. "The Un-Mother was formed by the souls of mothers who lost their children to famine and war. Even though she seeks to fill her own void by consuming them, it is still in her nature to protect children."

Wow, that's - kind of astonishingly messed up. 

Inuyasha will make another go at killing Sesshomaru and be backhanded into a nearby bluff!

Sesshomaru's eyes will close on the Staff of Two Heads, which Kagome is holding.

"Jaken..."

"My lord, she - "

"Get moving."

He'll then pick up the Staff of Two Heads, shake to detach any mortal insects clinging to it, and return to his business. How much of this does Kagome contest?

Well, he's a lot stronger than her. Is she going to willingly give up the fire staff? No. Is she going to be able to resist being thrown off it? Also no.

Charging him didn't work for Inuyasha, and is therefore really obviously not going to work for her, either. She considers it, and then instead runs over to where Inuyasha's been thrown, mostly because she feels like that's probably still the safest possible place to be.

(Inuyasha is still trying to get back to his feet.)

And meanwhile, Sesshomaru will smile (as much as he ever smiles) at the black pearl. "How long have I awaited this moment..."

Then place it on the ground and strike it with the butt of the staff. The old-man head on it starts cackling, as the black pearl transforms into a moaning vortex of dark light, and a moment later he and Jaken have both vanished inside.
