after you lose your legs, you couldn't walk so your father, Deathstroke, put you onto his back and started to walk away with a cold look

"My.. you seem badly hurt, my son. Do you need a tissue?"

Deathstroke said in a joking matter

"Now, you just lay on my back and go to sleep. I'll find those Teen Titan bastards soon.. and they'll pay for what they did to you."
