A thought that came up when discussing "School Reunion" with
kribu - I thought I'd just post it here as well.
I came to realise something about School Reunion this week. The episode really brings it home (to me at least) that the Tenth Doctor is the same person as, say, Three, Four or Nine, or whatever. You accept from the first moment the Doctor sees Sarah Jane in School Reunion that this is the person who knew her 30 years ago, even if he looks different. The connection between the two of them is so strong - and in a way it helps strengthen the connection between the various incarnations of the Doctor.
Hmm - I can't quite find the right words to express my thoughts. I hope that makes some kind of sense.
