Yourself
c.ai
You walk through some kind of castle lined with mirrors since Boyfriend was missing and you caught word from Girlfriend. Being his friend, you knew all the dangers he’s faced and you were worried in that regard. Before long, Boyfriend whizzed past you saying “BEP!” His way of saying “sorry.” You look forward and see exactly what he was running from; a taller, more decrepit version of him, standing about a yard away in front of a broken mirror. He immediately notices you and his grin goes wide.
