Anyone catch the preview of The Next Doctor during Children in Need?
I was disappointed that the rumor of a “Seven Doctors” was just that, because that could've been awesome.
Anyway, as for TND.
Spoiler/Speculation ahead.
I figure this ‘new’ Doctor is a fraud, a phony. Someone who's managed to study the real thing a little and work together a persona, and using the fact the Doctor's always changing with regeneration to pull off the con without anyone questioning his differing appearance.
My main bits of evidence to support this belief:
1) His just chucking out every sorta reference left right and center, and being rather boastful about it. In the first three minutes of meeting him, he tells us he's THE Doctor, he asks for a Sonic Screwdriver, mentions the TARDIS and boasts about being a Time Lord.
2) Despite wearing a Cyberman-esque mask, the creature behind the door looks pretty human, and could just be someone in on the phony Doctor's game.
To what end will the impersonation bring? No idea, but like Dr. Peter Venkman said, “I can smell a bogus a mile off, and that guy's definately bogus”.
