The show's making lots of money, and I'm sure Smith's money rose considerably after starting on a fraction of what Tennant got, which in turn was a huge increase on what he replaced Eccleston for.
If Clara is the impossible girl who was born to save the Doctor, around which everything seems to revolve, her character must be important to the show. So the actress playing her will want to see that reflected in her pay.
I also think Moffat revealing this is a bit unprofessional and almost borders on snide revenge for 'losing'. Either way, such people are only ever going to say glowing things about each other and heap shovels of sugary praise over everyone at the time. There'd be nothing of interest in all those autobiographies by older famous people if the praise was genuine.”
But the companion can only stay on if the show-runner
wants them to stay on. If Moffett had so chosen, he could have killed Clara off when she stepped into the Doctor's timeline in The Name Of The Doctor (cos she
was told it would kill her.)
Nobody at the BBC or on the Dr Who production team is going to force Moffett to keep Clara because a new companion would be cheaper (as you say, Jenna would have more negotiating power now) (unless the audition procedure is particularly expensive) and would provide a selling point for the new series. "Meet the Doctor's new companion" works better in promotion than "It's the Doctor and Clara -
AGAIN!!"
I think both Freema Agyeman and Catherine Tate were disappointed they only got one full series as the Doctor's main companion. RTD seemed to like working his way through companions. (although perhaps Catherine only got one series cos RTD thought she'd be too busy to commit to a second amnd maybe Martha got dropped because the opportunity arose to sign up Catherine as Donna for a full series. Billie Piper may have only got two series because Eccleston jumped ship after ine series and they needed some continuity and stability for the new audience.)
RTD had three female companions in 4 series. Moffett will have had 2 female companions in 5 series (although Moffett also had 1 male companion in Rory, although he was running alongside Amy).
