Harry Potter and the Deathly Hallows Part 2 Final Trailer on YouTube

I actually cried when watching this final Harry Potter trailer. It was when Harry was using the Resurrection Stone. He asked his parents, Sirius, and Remus to stay with him. Lily said, "always," and I just lost it. I also loved it when Sirius said, "until the end."

You can see lots of screenshots and gifs of the trailer here: http://phoenixweasley.tumblr.com/
