I'm still confused by how confident the Doctor was that there were no alternative-universe versions of himself. What's so special about Time Lords that makes them uni-universal? They developed the ability to travel through time and space and, also apparently through artificial means, gave themselves the ability to regenerate when they die. Not sure how that makes them unique to a single universe anymore than any other advanced race.
A bit off-topic, I know, and I apologize.
If there's a Torchwood in the alternate universe, then that means the werewolves were defeated by "someone" at Torchwood Manor, however the note of their being a president and not a primeminister does mean that the Royal family was pushed to one side somehow... So, maybe Victoria didn't survive?
