Summary: Donatello tends to write down his problems.
To see Donatello without a notebook was something strange, almost alien.
Whenever he came across a problem he couldn't solve, he wrote it down in sloppy letters, mixed with Japanese, English, Spanish, Latin and sometimes even French.
Whatever his mind slipped into, he wrote it down. Wherever he was, he wrote it down.
At breakfast, during move night, in his lab, in the garage, in the infirmary while checking their supplies…
Even in battle he made sure to save his observations for later use, so that he could scribble them down in one of his many notes.
How could those Foot ninjas become invisible?
How did Bishop build this technology?
How could he fight next battle to avoid committing the same error again?
How could his brothers leap so far between the roof tops?
But even if Donatello write notes, that is all.
He does not write down personal problems.
He does not write down his dreams, his goals, his nightmares.
He writes notes.
Not a diary.
So when he lies awake at night, shuddering and remembering his older brothers' deaths, his mind breaks a little.
It turns into a chaos, a chaos he can't control.
Maybe if he wrote it down.
Maybe if he could see it, he would be better.
Maybe if he told them…
But Donatello won't do that.
Because it is his chaos, and he won't ruin his projects with its messy organization, won't let it slip into his personal zone, his comfort.
He won't worry his brothers with his shaking hands and stuttering words.
And that is why Don let's his mind crumble like an ancient wall, piece by piece.
Because he writes notes, not diaries.
And he doesn't want them to worry.
So every night, he breaks down.
And no one knows it.
