Once again, it is with surprise and delight that I can give only one answer.
Also, because it's getting a little lengthy, I'll refrain from providing links to each previous day's answers, and do an all-in-one.
Day 09 - A Who-Related Photo That Makes You Angry or Sad.
I didn't have to think much at all, except to say that this is courtesy of one of the marvelous motivator makers over at Television Without Pity's "My Motivation is This" thread.
This one makes me both angry and sad. Let's face it, there are so many other things the Doctor could have done, so many things that would have convinced me that he respected his Companion, that he cared for her.* What he did was to find the quickest, dirtiest band-aid response one could think of - and he never even considered working something else out after he'd stopped the initial crisis. Donna needn't have remained the DoctorDonna, because I can accept that it might well have killed her. But there is no way that the Doctor couldn't have found a way to return her memories to her, not with the skills he has, and all his Time Lord Learnings. Instead, he took the cheap and easy way out, and indulged in massive wangst and wandered off ... Oh, I'm not going to get started on it, because it just makes me furious. Which, of course, fits the bill perfectly for Day 09.
(And, frankly, so many better ways RTD could have written this, but that's a whole 'nother rant.)
