Dear Eric Kripke, 

marry me. Seriously. 

You're my hero. 

You give me what I need when I need it, and even if you make me go through Hell to get that, I still love you. 

So yeah, marry me and let's be happy together. I don't care you already have a wife, I'm not a jealous type. 

With my huge, utter, complete love. 
JM

ps: Anyway, I still love John Winchester more, but since you killed him... >_>
Yeah, you killed the love of my life, then I guess that a part of me will hate you forever. But I'm gonna marry you anyway.

ps-2: Yeah, I saw All Hell Breaks Loose: Part II.  Supernatural officially owns my soul and heart and everything in between.
