I agree with Midnite. It looks as if the only people that could have possibly died in the PT fire were
[spoiler]Timothy, Roxanne, and Maggie, though I'm not sure.[/spoiler]
I'd have to double check on that though. I haven't seen that episode in a long time. XD
[spoiler]There's also the fact that most of "our" characters, although with their PT personalities, are DEAD by the time the fire comes. I'd consider the main characters to be Willie, Carolyn, Elizabeth, and Roger. Willie jumped from the tower room, as I can remember, and Roger killed Carolyn and Elizabeth, then was later killed by Angelique.[/spoiler]
It's just not the same as the destruction in RT for me.
