A Cerulean Aro Straight to the Heart by im_dead_tired
Fandom: Rise of the Teenage Mutant Ninja Turtles (Cartoon 2018)
15 Apr 2024
Summary
fics in no kinda/maybe chronological order that take place after the rottmnt movie.
they center around an Aromantic Leonardo, hence the namesake
(might branch out in the future we shall see, unfortunately i cant write plot so we shall see...)Leo also has ADHD, C-PTSD, is disabled in their left knee, is asexual (sex-adverse), and a demiboy (he/they)
- I wrote this for me okay! U get what U get.
(everyone's experiences are subjective and their own.)they vaguely reference non-canon events that take place after the rottmnt movie cause Leo has to be thrown into a blender until his knee gets fucked up and he meets the buisness end of a window in every universe before im satisifed. sorry not sorry.

Summary
How does it feel to be so very alone and so very forgotten?
Why do you enjoy tormenting me?
I will answer your question if you first answer mine.
Leave me alone.
Answer the question, Leo.
No. Leave me alone. Allow me a shred of peace for once.
Answer. The. Question.
I don’t want to.
You don’t have a choice.
I never have a choice.
Answer me.
I won’t lose control of my own mind!
Leee-ooo. Answer the quessss-tion.
Why?
Answer. Me.
I don’t want to.
How does it make you feel, Leonardo?
. . .
Despair.
Is that your answer?
. . .
Yes.
Good.
-or-
After being hit with a mystic attack that removes Leo's ability to communicate one unexpected turn after another takes his life on a downward spiral that rips him away from his family; seems to have no end; time and time again puts him face-to-face with the reality that where he is told he belongs is not where he wants to be...
and that makes him struggle with the answers to two important questions:
Can a hero be turned into a monster?
And does a murderer deserve forgiveness?

Summary
“…of course, he just had to see what his big sister had gotten herself into this time, so he went to look at the article she was angrily showing around.
His legs wouldn’t move.
A splash of panic poured through him, his eyes widening slightly as he tried to move them. He was stuck, which did his still-healing mind absolutely zero favors.”
—————
Most of his family is hanging out when Leo discovers his body has completely locked up on him. In the threatening shadows of midnight gloom, it’s far too easy to begin flashing back. His family, though also exhausted, helps him.
