Both of these posts are deeply troubling. It indicates that Bryce may indeed have had a fascination with fire.
Perhaps, and perhaps a totally different meaning, or something to do with a game he was deeply interested in.
As a side note...I LOVE burning brush, and seeing an area cleared afterwards. But I have no desire to commit arson, or anything sinister. Though the fire dept was calling on me once because the bank in front of my house was on fire. A bank I can't mow because it's too steep, and well, it just burst into flames late one night
