You were roaming the halls of the Glass Mansion, hands trailing along the walls, feeling the surface of the mirrors.

You stop in front of a door, opening it and walking inside. It's a bathroom, mostly normal looking, minus the blood all over. 'I'm sorry' is written in blood next to the bathtub.

You walk over, tracing over the letters with your fingers. As you're doing so, you feel someone touch your shoulder, their hand cold and bloody.
