Summary
Leonardo jamás pensó que, solo por flaquear una vez, su vida se vería envuelta en un declive total.
Eran ninjas, eran capaces. Siempre creyó que sus hermanos podían sobrevivir sin su ayuda; incluso cuando solía preocuparse de más, los creía fuertes, valientes... incluso más que él mismo. Pensó que podría lidiar con su propia tristeza y confusión a solas, en silencio, sin arrastrar a nadie con él.
Entonces...
¿Por qué todo se arruinó con algo tan simple como un labial?

Summary
‘What if you dreamt of someone else’s life?’
A constant sense of familiarity with people you barely know yet can’t help but adore. Knowing that somehow their presence and their words and their voices soothe something deep in your heart but you can’t explain why. Even after they become your friends you always feel like you’re on the outside looking in just a little. Even though it’s your life, and your world and your people— there’s something inside you that feels different and detached. Even as you laugh with them. Even as you love them. Even as you live alongside them.
Is this life really yours?…. And do you have the right to live it?

Summary
Kaiman stared down on Leonardo and said in his deep, nauseating voice: “The code of honor you choose live by is only for the weak and the fools, of which you are both.” As he continued staring at the much smaller turtle, he issued the very real threat: "The punish shock is capable of causing severe harm and possibly killing you. Do you understand?"
*Beep* went the neuro-tech disruptor attached to Leo that was used to shock him into submission.
Leo nodded his head without taking his eyes off the tempting jug of cold salvation in Kaiman's hand.
"And yet you still choose to refrain from taking a life?" he next asked.
*Beep*
Leo nodded his head again.
After that, Kaiman gave him a devious grin and had the nerve to tip the jug up to his own mouth to take a big swig right in front of him, before setting it down on the floor directly outside the glass wall between them.
“You would have earned your water today if you had obeyed my command. Let this be a lesson for you.”

In, and out, slow and careful--“Yo, Mikey! Get down from there!”
-- with a sharp inhale that made him choke he ducked.
