It's happening. I have the shakes, I'm irritable, slightly nauseaous. My heart races whenever I see a black Impala driving down the road. My stomach clenches whenever a Kansas song comes on the radio. I am suffering from a severe case of Supernatural withdrawal and I can imagine that many others out there in fandom are suffering as well. What is the remedy? You can only rewatch episodes so many times. Bloopers, commentaries, and behind-the-scene featurettes grow stale with frequent viewing. What is a fan to do?
One remedy I found during Spring Break was to spread the Supernatural wealth. Showing the show to people who haven't seen it before. My sister took to it with great enthusiasm, and watching episodes with someone who hadn't seen them brought back a bit of the excitement I felt my first time through. Especially when the person exclaims aloud at least 3-4 times an episode. She finally got completely caught up on her last day of Spring Break, and now there is a new Supernatural fan ready to watch the new episode on the 24th.
So if you're experiencing Supernatural withdrawal, trying showing the show to a first-timer. It will help bring back some of the excitement of your first time through and it will help the show by bringing in new fans.
