The act of becoming a jinchuuriki is beyond anything Rin can describe. The Mist-nin keep her awake on purpose, they give her no sedatives, no warning. They chain her down and laugh when she begins to scream.
She watches a man decapitated in front of her, the catalyst to the Sealing.
It's hard to explain how her body becomes aware of a foreign invader. But she feels herself pushed against her own skin, a claustrophobic feeling settling over her, as the Sanbi is forced down her throat. There is no room for him, there is no room for her, their chakra begins to stitch itself together and his thoughts become her own.
It's hard to focus beyond the rage that consumes her. Neither of them want this, the Three-Tails fights her as she fights him, but they are powerless to the jutsu that binds them together.
YOU ARE INCOMPATIBLE. Isobu's voice reverberates inside her skull.
She was made as a time bomb, a countdown to zero. She knows this because Mist told her to her face.
It feels like agony, and it tastes like bile, but after days weeks hours it is done.
She can feel herself dying, her body breaking down, attempting to reject the demon that she cannot keep.
But their guard is down, they think she is sleeping…
She runs.

Something is wrong. The mist-nin have come after her, but they are near-smiling, they are holding back.
They want her to race straight home.
Rin diverts her course, and she runs to the last person she can trust to do the right thing.
Kakashi refuses, but he doesn't understand. So she waits until he goes to strike, and then impales herself on his chidori.
"Kakashi."
She murmurs his name in gratitude, but there is only horror in his eyes.
I'm sorry,
but thank you.
