great ep - not a dry eye in this house at the end - well, except dp was was laughing at the rest of us 
meditrina i'm on bow tie watch too - you are not alone
i said on the last thread - in the ganger episode, the doctor said that they were all knocked out for an hour and that a lot could happen in an hour. there were two copies of jen - why not the doctor too (or anyone else for that matter)?
so i still think the doctor who dies is a ganger. the doctor has never gone through history drawing attention to himself in the way he did in TIA. i think it was a strategy to bring real doc and ganger doc together. arguably, 10 having a short lived marriage to the virgin queen wasn't exactly subtle - but then that seems to have been hushed up in the history books 
river i think really did believe the doctor was dead and was just arranging for him to have a proper TL funeral. it was canton who brought the right fuel etc to burn the body, as ordered by the doctor. she slapped him and said something along the lines of "this is too cold, even for you" when they met in the cafe afterwards. although river lies, just as the doctor lies....
also there was that wierd thing in the cafe in TIA where the doctor said he was 9 hundred odd years old, yet the doctor who dealt with George said he was that age a thousand years ago. could just be shorthand, could be an indicator that we are watching the adventures of the doctor who dies.
finally, sorry this is turning into a bit of an essay, someone made an interesting comment in Confidential that tonight's episode marks a turning point in rory's relationship with the doctor. maybe the good man turns on his time travelling friend?
