Forum:P.S.
If this thread's title doesn't specify it's spoilery, don't bring any up.
User:Tybort has removed references to P.S. (webcast) from articles because it was an unshot scene, so it's not a valid source. However, given that the scene was later released as an animated webcast, I do think that it is a valid source as much as any live-action ones, since the animated webcast version is a narrative source. 78.8.5.21talk to me 12:52, October 12, 2012 (UTC)

The Beeb's stated purpose in producing and posting it was to respond to the fans' clammour for answers concerning whether the Doctor and/or River paid Brian a visit or if he was to never be given closure, and about to when Amy & Rory were sent. So, yes, it's clearly canon and thus not only valid, but of TV series-level validity/canon.
