I always pictured them as being really good and close friends but nothing romantic, and the way i interpreted the scene in the blackbird, there was no romantic tension there, he was just conforting her as he was feeling her pain but i dont think or wish that theyll make them more than friends, not everything has to be about girlfriend/boyfriend relationships, a good, deep friendship betwen them would be good enough for me!
Oh yeah, go here http://www.geocities.com/xmenuncovered/storm4.html and scroll down to the bottom and read the last too, don't worry none of them are really nude, the auther of the page is just a perv ^^
Here, I have a section from the X2 novel, it's the scene on the Blackbird from the novel:
" You know, outside the circus most people were afraid of me. But I did not hate them I felt sorry for them, do you know why?" Kurt said, Storm shook her head. " Because most people never know anything beyond what they see with their own two eyes..."
" Well I gave up on Pity a long time ago." Storm said.
" I'm sorry to hear that." Kurt said, he reached up and placed his fingers against her cheek with a gentle caress sending a burst of heat rippling beneath her skin, together with a surprising thought: He's flirting with me... She didn't move away, because along witht he realization she discovered she liked it, she liked him.
