The first time I saw "Rose", I commented that by having the TARDIS dematerialise and immediately return, they had created a little "gap" that could be filled by endless Big Finish audios starring Ecclestone. It makes sense that those solo appearances Clive showed her were from that gap. We just have to wait until he needs the money
Yup, I didn't know about Big Finish yet, at the time, but, I immediately said you could stick any number of years into those couple of seconds (Any time he goes into the TARDIS by himself and dematerializes, there is room for anything to be written in extended Universe)

Where are we going? And why are we in this Handbasket?
