David Tennant being a lifelong Doctor Who fan who was inspired by the show to act, becoming the Doctor and Ncuti Gatwa who watched David Tennant and was inspired to act, playing the Doctor opposite David’s Doctor is the most beautiful thing
because obviously the doctor is about to blame donna for spilling the coffee, but he catches himself, backs off and apologizes. and it's not him catching himself in a "this is a pointless argument because i'm right and you aren't getting that so i give up" sorta way- because in that beat after, he isn't irritated, he doesn't start trying to figure out a way to reiterate his point. it's him catching himself in a "that was the wrong thing to say and i regret that" sorta way.
it's him catching himself becoming another one of the voices in donna's head calling her a screw up.
turn left is literally the most insane episode ever written. yeah the main character would kill himself if he didn't meet his best friend and the UK government is like 2 bad days away from putting all non-english people into labour camps. also all your favourite characters died trying to do what little they could. wouldn't that be crazy? anyway time for the daleks again
Not-Donna: I see into your soul. I know everything about you. I understand what you’ve been through. And I am going to use it against you and take over your universe.
Not-Doctor: [crawling upside down] donna donna donna donna donna donna donna
this scene. this fucking scene. when i watched this the first time it really struck me how much 14 has grown. 10 wouldn’t have let that argument go. they would’ve kept pushing buttons until one of them stormed off. but 14 stops, cuts himself off mid-sentence and walks away to take a breath.
“no,” he says. no we’re not doing this. no it’s not my fault. no it’s not your fault. it’s a shitty situation and they’re both stressed and afraid.
and then he apologizes even though he didn’t start the argument and he didn’t spill the coffee. and it was definitely donna’s fault but sometimes being best friends means you let things go and you lie a little because your friendship is more important than being right
AND THEN HE COMFORTS HER. without her asking and without her initiating it.
