Goodnight Vienna

Goodnight Vienna was a phrase the Tenth Doctor once used with Rose Tyler upon escaping from a time loop. He used it to indicate that they would no longer be having to perform the same actions over and over again. "It's a definite goodnight Vienna this time," he said, "No more repeat performances!" (COMIC: Interstellar Overdrive)

Behind the scenes
As it was used in the last panel of Rose's final non-parodic appearance in the magazine, it also could be read as a meta-fictional farewell to the character.
