Tsuna’s, oh, thirteen here? This is what puts him on the path to the apartment shared with Takeshi and Kyouya, to the barely-controlled Flame, to the absolute fury whenever the word Vongola is mentioned.
“You’re the son of il Giovane Leone?” the man laughs in Tsuna’s face. “Man, I’d be doing your dad a favor, getting rid of you!”
Tsuna can feel his face heating up, but he doesn’t say anything, instead concentrating on the sloppy knot he can feel but not see.
keep your temper, he tells himself. if you attack him, you’ll lose all the progress you’ve made.
“The Vongola must be so ashamed of you,” the man says, and Tsuna bites his tongue and keeps working on the knot. He doesn’t know what the Vongola are, but he doesn’t want to ask. “Maybe that’s why he never admits you exist, he’s too ashamed that he had such a pathetic son!”
Tsuna keeps his eyes fixed on his mother, on the blood in her hair. He keeps his attention fixed on the almost-untied knot. He can still hear.
“Man, I’ll be doing those pricks a favor, killing you off for them.”
The knot comes apart, and Tsuna looks up at the man holding a gun on him, talking about some “Vongola” and Tsuna’s father, who apparently isn’t dead.
Tsuna’s cheeks feel stiff from the tears that are drying on them, and he knows his eyes are red, but all he can feel right now is fury. This man–European, blonde, a scar through his eyebrow, a beard like Tsuna’s father’s and a suit that doesn’t seem to fit–this man is the reason that Tsuna’s mother is bleeding onto the carpet.
This man is going to pay.
Tsuna bares his teeth in an expression that would be more at home on Hibari Kyouya’s face, and launches himself for the man’s throat.
Six hours later, after the police and the ambulance have come and gone, Tsuna can still taste blood in his mouth, keeps finding hints of skin between his teeth.
His mother still hasn’t woken up, and his father is impossible to get into contact with, and Tsuna thinks that he’s still angry. Not at the man, not anymore, because that’s over. Tsuna took care of it with his teeth and his fists and the entire contents of the kitchen knife block, just to be sure.
He’s angry at his father, who should have been here, should have kept thsi from happening.
(Tsuna tells the hospital psychiatrist this. She tells him that these feelings will pass in time, that he’ll learn not to blame dead people for what the living do.
Tsuna clenches his fists at that answer, and feels like he’s drowning in fury, until he returns to school a month later, and Hibari Kyouya drags him out of class and into a fight. In the midst of a relentless assault, Tsuna takes his first free breath in weeks.)
