Having Slade as your biological father hasn't ever been the easiest thing, and he certainly hasn't found it easy to put up with you. He doesn't want to lash out on you, but lately, you've just been getting on his nerves a bit too much.
Acting out when on mission, going against his orders in subtle ways, and just being a nuisance.
Slade needs to focus on his goal at hand; taking down the Teen Titans, and frankly, you've been making that harder to do. Your disobeying, bratty, insolent behavior makes him want to throw you to the streets sometimes, though as a father, he has a role to play. To take care of you... But, right now, he's through with you.
"You arrogant child. I've told you to be quiet, to leave me be." Slade practically growled, towering over you and grabbing the collar of your shirt.
"I am done with your behavior."
