Doctor who Journeys End spoilers

Here Are Some things and spoilers about journeys end.

The Doctor's extermination by the Dalek seemed to be a glancing blow, so could it really bring on a full regeneration? David Tennant has been seen filming the next Christmas special.

What is the significance of The Doctor's hand in jar that bubbles away in the Tardis? The one you may remember was cut off by the Sycorax. It's been very noticeable of late. There are strong rumours that it plays a part in keeping the tenth Doc with us.

If Sarah Jane was really going to be exterminated, then it was a bad idea of Blue Peter to show a clip of her from the next episode - alongside Mickey Smith! Could the self-proclaimed 'tin dog' be her saviour from the Dalek attack?

Is Harriet Jones really dead? We never saw her die and she seemed to be doing Davros a favour by coaxing The Doctor out into the open along with his nearest and dearest. Double agent perhaps? She could be the new Lytton - a character familiar to fans of 80s Who.

What or who is lurking inside the Supreme Dalek?

Who has Rose been communicating with back in her parallel world?

The Doctor's daughter Jenny is still lurking in outer space - could she make a return to save the day?

Will Russell T Davies wait until the specials before revealing the identity of the person who took The Master's ring in last season's finale?
Thank You.
