Ah ha. I was reading David Tennant's acting right in the infamous street chat between the Doctor and Rose.
When I first saw it, I was like, 'dude, he didn't just...basically flat out say it without saying THE WORDS? They aren't going to go THERE this early, are they?'
Oh yes, he totally did.
When I first saw School Reunion, I exclaimed a big old OMG of shock to my DW-watching squee buddy, elrina753 and I was just so completely amazed that they were totally going there. Then, after reading clever folk's thoughts on the ep, I decided I was partially wrong. Clearly, I was taking it too far. The speech he gives about having to watch everyone else decay, wither, die while he doesn't, it wasn't as Rose-centric as I thought it was. I was just watching it with Rose-colored glasses as it were.
For when you're a Rose fan, you're an idiot, you see. *rolls eyes*
Dude, it so is. The relationship implications I picked up on, they were there. He doesn't say he loves her then, he was about to. Just rewatched it now to confirm that nagging thought.
"Imagine watching that happen to someone you..."
Rose picks up on his hesitation and his response? "You can spend the rest of your life with me, but I can't spend the rest of my life with you."
That is fantastically angsty and terrible. Because she would have, she wanted to, for the rest of her life, forever. Hell, he asked her how long in that scene in Army of Ghosts and that scene was not underscored with 'the Doctor is not happy about this answer.' Quite the opposite, really.
Man, why I am all over the desperate and painful aspects to their relationship?
There's a lot more, there's a lot of fun and a lot of WHEE and a lot of awesome 'Team TARDIS: Public Relations' moments that I will cherish forever, but right now I'm just wallowing in the angst.
His: "No. Not to you," response to Rose's question of how she'll be left in the end. It was a beautiful lie, that he believed in, completely and utterly. Even though he sends her away to survive (Parting of the Ways, Doomsday) and she refuses each time. And it turned out to be true in the end.
And he burns up a star just to say goodbye. And he doesn't get to say the words (because he's a schmuck and I need an icon of his Emo!face with the word 'schmuck' on it), but he would have.
I was right. I should do a snoopy dance. Of joyful angsty goodness.
