You wake up.
The hallway is dark and quiet. The first thing you notice is all the junk you had in your pockets is now scattered on the floor all around you - your flashlight, the envelope, the photo of the two kids... The second thing you notice is the sharp stinging in your arm. When you inspect yourself, you find what looks like shards of purple-hued glass embedded in your arm. You make a face and pick them out.
It must be the remains of the memory orb you got earlier. Was what you just saw... a memory?
Bai's memory, even?
