Ooo...now I'm all interested in what happens later! If only it worked out like that... 10 getting closure with Rose and Martha getting a second chance to travel with the Doctor...but poor Donna! She actually became my favorite of the 3 new companions because she was just his friend w/out all the romantic entanglements...so of course something bad has to happen to her, eh? (rolls eyes at Rusty)
