A couple questions about Tony Stark: Does anyone like him? Not just enjoy watching him (frak me, he's a morsel), but feel willing and able to defend him as a person? Would you ship him with anyone?
I wouldn't, but I'm trying to pinpoint some kind of tingle that I got from watching the character and his removable glowing heart. I'll just be frank here - is there a fetish to encompass this? I do not know fetishes so I must depend on my flist to identify them for me. The closest parallel I can draw is Angel being forced to rely on his highly beneficial but unwanted vampirism (but even immortality does not glow).
Oh, and I'm feeling a little more okay about Scarlet Johanssen (sp?). She's Black Widow, aye? She'll do.
