I just want to say I've been watching this show from the beginning. The last episode pretty much almost brought a tear to my eyes because I really thought they're father came back. That episode has to be the most heart breaking show I've ever seen in all of tv to me..... I'd like to ask if someday they can cast him permanently because he brings that element that they need in there universe. Hopefully after this episode others will write CW, the writers or whoever reads these things to recast John Winchester. Not to say the direction isn't good but that little brief episode opened a great possibly to better stories where the whole family battled for humanity together. I just want this show to be great. No it's already great but even greater. I'm just one voice and only speaking about one episode that touched me dearly. To the actors and writers and CW thank you for supernatural and thank you for that episode in particular.
