It is so incredibly intriguing. Everything: Donna, the importance of the Doctor and Donna together, Rose. Rose being all mysterious was brilliant. I can't wait until next week. And then of course, on top of the mystery, we have apparently every single thing a fan could possibly want in the trailer.

And Donna's storyline, it's really turning into something amazing. I did fear it would be resolved in this episode, and Donna put on the sidelines for the finale, but in answering the question about her back it's cause there to be more questions about Donna. I am loving this series so much!
