Oh, I wasn't trying to say Luke=Spike or anything like that. I was just using his words to describe it. I think he did it more than one, though I don't know why.

As a tangent to your tangent, though, I do kinda think Joss does what some fans do and automatically associates characters with other ones even if they're entirely different. Bangel as boring as it was wasn't really Bella-Edward like, but that's what he compared it to and he basically turned Buffy into Bella in the comics.
