Sherlock

A couple of days ago, I posted about getting addicted to Sherlock. If any of you have gotten thru the first and second series, then you know that Sherlock fakes his death. I was going thru fanfiction, like I always do when I get addicted to something. All these stories containing the phrase, "I believe in Sherlock Holmes". Am I missing something? Has there been a promo for Series 3 that I don't know about? Another thing, I really don't think Sherlock and John could possibly be gay together. Not in they're portrayed. They wouldn't even make a good couple. In the Harry Potter universe, I can see Harry and Draco together, but Sherlock and John? No way!
