Alright, guys. Let’s set shit straight here.
DID ANY OF YOU PAY ATTENTION TO THE FUCKING EPISODE? NO? OKAY. WELL LET ME BREAK THE FUCKING THING DOWN FOR YOU.
"Why do you have to break mine?"
“Because Amy read it in a book.”
See that? Remember when Amy was reading ahead and the Doctor scolded her? Do you remember what he said? No, of course you don’t because apparently no one paid attention to the goddamn episode.
Reading a certain time/place/event turns said event into a fixed point in time. If the Doctor could’ve let Rory kill Hitler in “Let’s Kill Hitler” without reaping the consequences of disobeying the rules time and space and creating a paradox/destroy the time vortex/create a time fissure/wipe out the universe, don’t you think he would’ve jumped at that opportunity IN TWO HEARTBEATS? Of course he would have. Let’s be real. Too bad the Holocaust was a FIXED POINT IN TIME.
"Amy, look. There’s someone with the same name as me."
REMEMBER THAT MOMENT WHEN YOUR HEART SHATTERED INTO A BAZILLION PIECES???????
That was Rory. Reading his death. CONFIRMING. HIS. DEATH. FIXED FUCKING POINT. With me so far? And what did Amy do; she suggested that they go back and make ANOTHER PARADOX. ANOTHER ONE. AS IF THE WHOLE CHUNK OF TIME AROUND THEM WASN’T ALREADY FUCKED UP. THE DOCTOR SAID “NO AMY THAT WILL FUCK SHIT UP EVEN MORE WITH TIME WE CAN’T DO THAT SORRY.”
So what does Amy do? THE SAME FUCKING THING AS RORY. SHE SEALS HER FATE. DONE DEAL. DONE. FUCKING. DEAL.
The Doctor then reads her name on the gravestone. IT IS PHYSICALLY IMPOSSIBLE AT THIS POINT FOR THE DOCTOR TO EVER SEE AMY AND RORY AFTER THAT MOMENT BECAUSE TIME WILL LITERALLY FALL APART. The ENTIRE bit of time became QUANTAM LOCKED and there was nothing the Doctor could do after that. NOTHING.
SO FUCK ALL OF YOU WHO DIDN’T WATCH AND THIS IS A PSFUCKINGA BROUGHT TO YOU BY AN ANNOYED AS SHIT WHOVIAN WHO ACTUALLY PAID SOME FUCKING ATTENTION TO THE FUCKING EPISODE. STEVEN MOFFAT DID NOT WRITE POORLY. YOU SHITS JUST IGNORED EVERY WIBBLY WOBBLY TIMEY WIMEY EXPLANATION HANDED TO YOU.
GO BACK AND ACTUALLY WATCH THE GODDAMN THING. THE WHOLE EPISODE WAS TIME-SENSITIVE FROM THE FUCKING START. THE EXPLANATIONS ARE REALLY FUCKING HARD TO MISS.
FINALLY, someone has explained it properly. Thank you, THANK YOU to this wonderful Whovian. Here’s a gold star.
