- Adam is in fact Davros (Dalek Leader)
- Adam is the creator of Davros and the Daleks
- The TARDIS is actually a weapon
- The numbers that have been used throughout the series are the phone number to vote The Doctor out of "Big Brother"
John came across the following link which may give more of an answer than anything. I've already read somewhere that The Doctor goes missing/"killed", leaving Rose to escape and navigate safely using the TARDIS. Lets pray that K9 pops up somewhere - so pleased I dont miss the very last episode due to holidays!
