Billie Piper 'moving on' from 'Doctor Who'

i hate it too billie....

can i get a "thank god"? she was terrible, i'm glad she'll never come back.

billie was fine as a companion and then she left - which was all good.

then she came back... look, fine, she's kinda hot in an unconventional way but having a dead and
gone character come back is too much. i'm glad she's gone but i still want more of that hot, hot
cup of mocha freema agyeman - for eye candy only, of course.

i liked rose, but it just would not make sense if she were to appear in the show again. i agree with
her, that ship has sailed.

i don't really see micky or martha appearing again either, or a need for them to make an appearance.
the only two i can see making a return is captain jack and possibly donna (her story never felt
'complete').

martha was also supposedly dating (engaged or married to?) some doctor, last i know. how she ended
up with micky is weird.

but i would suspect they both work for unit now.
