    Deathstroke walks over to the Teen Titans HQ, holding your hand, chuckling, with you under his mind control

    "Now, boy.. Do you see that base over there? That's the Teen Titans base. I want you to explode that.. and it will kill all the Teen Titans.. and only after you've done that will Daddy stop controlling you. Got it, son?"
