Back on 11th October I wrote:
I am trying to find any mention by Phoebe of Oriel during the time she was applying and before she went there; I did not hear one at the time, in spite of listening quite carefully because of various discussions about where she might end up, and so far there has been none in the recordings I have listened to. (She wasn't in all that many episodes in which it might have been discussed between 6th October 2015 when Jennifer said she was applying for Oxford, and her setting out there the following year...)
because MUM had said "Phoebe mentioned it at the time."
There were 16 episodes in which Phoebe spoke between 8th September, 2015, and 2nd October, 2016, and I have now listened to them all. She did not say the word "Oriel" in any of them. She spoke of "Oxford" every time she mentioned going there. To Alex, to Jennifer, to Roy, to Elizabeth, to David, to Brian, to Josh...
(She apparently had not chosen a college on Tuesday 8th December, 2015, when she said, "It would be great whichever college accepted me." That was after she had had an interview, which I would have thought would have been at the place she chose...)
There are a couple of episodes in which her having got a place at Oxford is discussed by other people, and I could have a listen to them just in case they say the college name, but between applying and leaving for the college Phoebe herself seems not to have named it.
(Yes, I know, OCD and ridiculous, but I have a cold and I was feeling I had gone mad, so...)
