Me and my friend were going through all these new *Theories* that we have read and we though we were just debunking...
We went to the PaP room and he told me to look at the roof and one of the lights where glowing.. It didn't look like it was on though.. just look like a cheap 2D one.  I have no idea what made it go on, we tried going through and doing everything again but no luck :\.
