Barty doesn't know how he ended up there but he wished he didn't.
In the dark room there was he and the mirror.
The reflections of the mirror changed fast one after an other. He couldn't understand why it wouldn't show his desire.
It was all too fast. He could not keep up with the frames.
Then it all went quiet.
The mirror showed Barty all alone...
He couldn't understand why it haven't showed Evan and Regulus. Mostly Evan.
He imagined his life with his Rose in a quiet apartment that was only filled with their laughter.
Then it hit him.
He realised why he and Rosier would never work out like James and Regulus.
His desire was to be alone.
He never knew family or home so he couldn't starve for it. He laughed at this fucked up statement but after all he hated himself for it. Who would wish for loneliness? He left the room. He lit up a cigarette and inhaled it sharp.
If he can't be his own, he would be better dead.
