Supernatural fans: I have some questions about the show?

It was God who put Sam on Dean on the plane. Yes, Becky was writing one of those sick slash fictions about "W". Which is about Sam and Dean having more than brotherly love. I never read one. I didn't even know what it was until I saw a video on youtube that said "W" and I clicked on it and found out the horrid truth. In my opinion its pretty gross, but some people like it (I don't know why). The episode that is going to air on April 15th is "My Heat Will Go on". I checked on imdb and that's what it said. I also checked on the CW and it showed the same preview and said that it was "My Heart Will Go On". I don't know what that episode is going to be about, because I didn't read the info. I hate reading the info of the episodes, I feel like it ruins it lol. I didn't finish reading the last part that you wrote. I read up until "where Sam and Dean are trying", after that I stopped reading cause I don't want to know whats going to happen. Lol.
