@Soundtrack-HW, i impleied something like that when i said accident...
Although my bets lean on a cigarette rather than a match, but whatever!
The only thing i found suspicous of why
William was in the building... Was he the only one? Because it doesn't mention anybody else, and it makes you wonder what sort of mission he could have been on that made him go into a deserted building that just happens to go asmoke. Seems a little to coincidental.
Although i just think UR didn't plan for such a debate, and just kinda threw it in there. They just didn't find a back story necessary.
I found it rather misfortunate to not get a jared for UR. I'm really eager to find out about the mystery of jared, and room 13...
Although i think the room 13 answer will be unknown, jared I'm sure we'll get the answer to soon
