Sheer heat. It's embarrassing for me to admit that such a large scar on my leg was caused by a hot water bottle. You probably leaned on something hot. As for Fray, yes and no it's not. Mind you, "once more with feeling" is my favorite episode and the only one I will admit to having seen so my taste is suspect. It's not part of the 32.0 GB of comics on my files server, nor did I bother to back it up so I don't have it. It would not be hard to obtain again.
