Back when I used to writing Mutant X, I started a fic where Jesse phases to evade a bullet. But this is a different sort of bullet that IMMEDIATELY neutralizes his powers the moment it comes in contact with his skin. So basically the bullet gets lodged inside him because he's back to solid before it passes through him and much angst ensues... sound familiar?
That's right... the bloody show writers read my mind and made a kickass episode out of it and... ugh and I abandoned the fic. *sigh* Now its happening again.. in SPN.
