Day 123

The scene is a simple one, but it require a little setup.
So:
Miles is a bigger guy. He looks imposing and is actually very strong. Also tough.
But he's a gentle giant, who would rather beat himself up, than let anyone else get hurt.
Probably why he's a professional wrestler - entertainment: not Olympic.
Miles is a jobber, he takes falls and gets beat up by hero characters in order to help get them over in the eyes of the fans. Miles is well practiced at taking a bump from smaller guys.
So Miles found this cat hiding from the rain, and brought it home.
After drying it off, he realizes the cat wasn't a cat, it's a shape shifter.
But the shapeshifter isn't a shapeshifter, either. They're in a shapeshifter's body, that used to belong to a body snatcher, who took their body, which was that of a warrior mage. Now, they need Miles' help to stop this body snatcher, before a terrible curse is unleashed on the entire town.
. . . fast forward to Miles fighting this shapeshifter, who chooses to swap bodies with Miles, due to being bigger and stronger.
Something kind of snaps in Miles ...
A man who has allowed himself to be beaten down all his life, who makes his living taking hits, now finds himself face to face with . . . himself.
He's confused, out of body experiences do that to a person.
He's no longer himself. Because he's starring at himself.
He's seeing himself as others see him.
All he can do is ask why? Why does everyone want to hurt you? Why do you let them? Why don't you tell them to stop?!
None of this is said aloud of course. 
Words can't fully articulate this odd mix of inward outward loathing.
He strikes the face that was once his own. Then again. And again.Striking down the shell that was once his own.
His crooked teeth, his lazy eye, his bald head.
Every blow is a release of his own self loathing.
Why are you ugly?
Why are you fat?
Why are you the way you are?
He stands over his own body with fists raised, finally able to see himself as all the bullies of the world have seen him his entire life.
Why don't you tell them to stop? Why don't you want them to stop?
The fire in his new eyes are extinguished by tears.
Just tell me to stop . . . tell me to stop hurting you.
