Rory is hilarious.
At least we won't get an Amy departure where she suddenly leaves the Doctor to marry some recently met random character.
It would be nice to have the Doctor travel with just a bloke for a while the Turlough audios make for a refreshing change (especially as he was in some ways like a young version of the Doctor himself).
It might work if Amy left and Rory and the Doctor traveled alone (at least for a while).
It would be like The Odd Couple on the Orient Express in space...under the sea...
