This latest trailer, we learn SO MANY things. Clara was born to save the Doctor. Her parents met under a set of circumstances that bear a striking resemblance to where Rose’s tragedy with her father occurred. When Rose looked into the Heart of the TARDIS, she could see through all of time and space, and she wanted her Doctor safe. In the above trailer, we see Clara jump into the timestream directly through the TARDIS. The second that she does that, Rose will know about her, and that she’s trying to keep Eleven safe the same way Rose wants to keep Nine safe. In that moment, she can guide Clara. She made Jack an undying fixed point in time, and she made Clara exist everywhere she needed to. Rose put her everywhere and everywhen that she needs to be to save her Doctor. Just like with Bad Wolf, Rose sent herself messages all across time and space, and this is why every time that we’ve seen Clara, there’s also a mention of (a) Rose, as well as why Clara has met The Doctor more than three times. In the preview episode, The Doctor says that Clara is perfect in every way for him, always brave, always funny, always exactly what he needs. In the “Next Time” clip, the Doctor attempts to cross his own timeline, and the TARDIS doesn’t like it - which probably explains why the TARDIS doesn’t like Clara in the same way that she doesn’t like Jack, because of what Rose did to/for them.
But that’s just the tip of the iceberg, because the season finale ALSO leads in to Doctor Who’s 50th Anniversary, and the ending of The Name of The Doctor was filmed AFTER the 50th Anniversary had already started filming, so we might even see Rose next week to tie everything together.
(Different potential spoilers about the 50th past here).
I am almost positive that John Hurt is playing the role of The Valeyard - who is tricking The Doctor by pretending to be a lost regeneration of the Doctor’s from the Time War. If that’s the case, we now now what role Rose and Clara will be able to play. Rose knows the Ninth Doctor better than anyone, and I don’t think that she’ll believe the story. Rose and Clara have interacted within the Time Vortex, and I think that together, they can uncover the Valeyard’s lies that The Doctor is too afraid of remembering / too haunted by the horrors of the Time War to properly recall. The psychic warned Clara about the sliver of ice in The Doctor, and I believe that is what’s going to be confronting them in the 50th. The darkest aspects of the Doctor himself made manifest and trying to outwit him. What The Valeyard could be planning - I have no idea, but this looks like it’s going to be an absolutely STUNNING lead in to one hell of a 50th Anniversary celebration.
