Remix: They Laugh With All Their Might [Fifth Doctor, Donna Noble, 100 words, rated G], by purple_bug
Not many people would put this much effort into recovering lost memories. Most would fret for a while before eventually coming to terms with the loss. Not Donna. He must've seen that something special in her; he can see it now, in fact. She's determined, headstrong, speaks her mind. He's reminded of Tegan, and he smiles wistfully for a moment, glad that she finally got to where she wanted to be, but still missing her. He's always been a bit odd like that with his companions; they can irritate, interfere, condescend and make fun, and he still thinks they're fantastic.
