doctor who

Bilie piper played Rose in Doctor
In the last chapter of season 2, she and her family went to the balance world
normally TARBIS (the time machine) cannot be able to travel there
so Rose should not travel with the Doctor anymore

however i am not really sure it...
because last time TARBIS was got a big problem, they(ROSE and DOCTOR and Rose&#39;s boyfriend<i>) was gone to the balance world by an accident. I cannot sure TARBIS won&#39;t have accident again, if it will be balance world again, i think the Doctor will find she again!!!</i>

佢起第二季最後一集被困平行世界(cyberman果個)，
同佢阿媽，micky一齊(仲有佢起平行世界ge阿爸)，
因為阿bilie話唔做，不過睇黎劇組留左後路~~

billie piper飾演的Rose Tyler在第2季Doomsday一集離開，第2季第11集Freema Agyeman飾演的新拍檔Martha Jones出場。之後billie piper只係flashback度出現過。
