hmmm... I ticked 'no' but as long as she doesn't stick around forever - I think I can deal with her - it would add a bit of angst for Jack as it always seemed painfully obvious that the Doctor was first attracted to her with everyone else in the queue behind her and since Jack hooked up this time after Rose was gone he was secure in his place in the Doctor's life... but if Rose returned...

poor Jack - don't get me wrong I love hurt/comfort emotional as well as physical and as long as the Doctor is there for Jack in the end....
