I just watched Supernatural 4x18. OMG, CAN YOU YOU BE MORE AWESOME, SHOW? ( insane fangirling/geekasm behind )

I've also watched LOST 5x10, I'm so late, it's ridiculous. But wow, mindfuck. I love Sayid because he's hot and he handles his problems like a man (not like others, I'm looking at you, Jack) but what happened at the end of that episode is just...WOW.( spoilers ) I'm not gonna make theories but I hope it gets explained or something. Where's Daniel and his rules when you need him? Anyway, you guys probably know more than me but please, no spoilers! I like to discover the mindfucks on my own :)
