"You've been trying to kill me for centuries and here I am, dying of old age. If you want something done, do it yourself."
Can we talk about how savage a line that is to the Daleks. This is easily one of my favorite Doctor to Dalek line.

Daleks: THE RULES OF REGENERATIONS ARE KNOWN
Doctor: Bet

From the Daleks' perspective, it must seem like he regenerated out of spite from being told the rules of regeneration.

My headcanon is, that the Dalek machines picked up his regeneration half a second slow.
And what actually made them hit the Emergency alarm was just the tone of his voice. Not the tone of an old man, they could handle that. But the tone of THAT individual, that had denied them their success, so many times.

Just noticed the clock dings 13 times at 12 oclock.

The clock broke the rules, then exploded.

Neat.

Daleks: NO NOOOO YOU CAN'T JUST BREAK ALL KNOWN LAWS OF YOUR OWN BIOLOGY NOOO

The Doctor: haha regeneration energy go brrrrr

It's incredible how fast Eleven switches from totally hopeless to full of life and grandstanding like his younger self when he gets his new regeneration energy. Matt Smith is an excellent actor who gets one last chance to show his emotional range before saying goodbye. And it is wonderful.

the daleks didn't notice the crack, i like to think that in their last moments they legitimately believed the doctor broke the rules of regeneration just to spite them for trying to tell them to him

"did you mention the rules?"

basicly:
Screw the rules, I'm the main character

I always find it funny and clever how matt smith's doctor dies of old age while he's the youngest actor to play the doctor to date

To me "Never ever tell me the rules" is one of the defining lines not only of the 11th Doctor, but The Doctor as a character.

This scene has a double meaning. It’s Eleven’s victory. His final victory. His absolute joy at finding he still has time left. It’s the most explosive regeneration of all time, energy bubbling like lava.

But behind our smiles at his joy, we’re crying. Because regardless of his death or regeneration, it’s still over. We’re never going to see him again.

"The Doctor is regenerating!" has the same energy as "The Slayer has control of the BFG"

I love how they say "Emergency"

Not 'alert'
or 'warning'
or 'attention'

The doctor is emergency level threat.

I like how happy 11 is when he realizes he isn't going to die. A lot of times you almost feel like the doctor is tired of living, but in this moment you can tell that he is ecstatic about being able to live on.

I still love that the Daleks never fire at the Doctor until too late. I mean he's on his deathbed, there is no precedent for any normal timelord regenerating a 13th time, and they hate him more than anyone in the universe. But not a single shot fired. They don't want to risk it. They would rather stand vigil as he uses up the last few drops of lifespan than actually shoot at the Doctor. An entire army of zealots just watching their greatest enemy die because they know there is some way he would turn it around if they went too far. Even when he lost hope and gave up. They didn't dare to push him, just let him sit there in despair while they moved on to killing everyone else.

This beautiful show is never going to end until he turns ginger isnt it

Only now do I realise that as the doctor is regenerating that the clock strikes 12, clever, very clever..

I love how 11's regeneration shows off every single facet of his character. From his moody darkness to his insane energy to his tearful acceptance of how things are. The best regeneration in the series if you ask me.

I love how the Timelords take a second to keep the crack open before closing it to make sure he's smoothly transitioning into his next regeneration cycle. Proof the Timelords have a heart and care after they lost it to the Time War.
