oh and Jackie definitely she has been seen with rose.

If the person your refering to is not among all the people i listed then who?

Since watching Waters of Mars and various bits of information and rumours, we know that Jenny isn't coming back for christmas she might be back next year when matt smith takes over, the human doctor might not because it looks like the rose we'll see in the end of time may be a past version before she met the doctor.

IDIOT!!! YOU FORGOT THE MAIN PERSON!!! (wellll, not really but still!!!) I'm really mad. IT'S ROSE!!!!!

whoa no need for name calling there sagigrrl.

calming down now...i was a little hyper then... SQUIRREL!!!...what was i saying again? oh yeah...

I did put rose.

why do they alwasy bring back rose?! i think they need to just let her go. How is the Doctor going to get over her if she keeps coming back!! she might as well be in Torchwood. (and you forgot the marriges)

The way RTD ended torchwood, I'm almost nervous to watch the End of Time 2 parter.

I don't want David to leeeeeeeave...
