Is Catherine Tate ONLY going to be putting in a very small cameo appearance? maybe even just a filmed flashback sequence, or as a 'background' character to Bernard Cribbin's companion?? It does worry me as I LOVED CT as DN and I would love to see her come back pretty much fully for the last two shows - but it's looking a bit grim so far...

Nah Doctor Who Magazine 408 in confirming CT's return gave the vibe we'll be seeing the Noble's Christmas..

RTD quoted

"If you thought the Noble-Motts suffered enough during the holiday season in The Runnaway Bride and Turn Left,thats nothing compared to what happens to them this time.Christmas must be cursed,for that family!"

and David and Catherine are soo good together bound to be reunited surely .
