i guess it was kind of inevitable - its a shame tho' as she's pretty good. i guess she's got more reason to get out for typecasting reasons than ecclestone does really - we all already know he's an established quality actor who could easily do other stuff - but this is only piper's third serious role. plus, didn't she mention recently that she might like to do some more music?
also - they've gone to great lengths to shed light on the so she's just upped sticks, and keft her mum wondering where the hell she is question, with plenty of back and forth to earth - first phoning her mum, then going back, then going back in time and meeting her dad etc. with all that done, its set up to move on from that - so it really seems too soon to go for that reason - the covering of these bases will now be disproportionate to the time spent in the role.
but after the whole bruhaha before it started, and that huge buzz about, which has largely actually delivered, its a real pity to see it change so much so soon.
