You
For a moment, he looked at her with confusion, much like a broken child. "Eh? Who is you?You are you but I am me, I am, I-"
He stumbled and gasped for air, and his eyes darted around. Where was he? What was going on? Where were everyone else? He clutched his head in confusion and pain.
"Aah...aaaa..."
The next thing you could hear was the crunching of bone. And then there was nothing. No sound, no worrying, no disturbances. Peacefully quiet, as all things should be. His hand just stayed inside his crushed skull, while black tendrils wriggled their way out of the wound and the broken eye sockets. The hand that was you that was him that was not the you who interrupted You, the you who she knew as the you who served her.
He could never be anyone other than who he was. Sorry, but his vessel would have to suck it up.
"Sorry about that. This body of mine can be prickly." He chuckled while his face began to crawl back into its original shape, and the leaked brain matter wriggled its way back into his skull. "Honestly... I don't want anything at all. I'm already as happy as a man can be."
He hugged her without saying another word, without a warning or anything.
