After the Justice League's successful defeat of Darkseid years ago. Their young children now follow in their footsteps. And when they join the team: Young Justice, they learn that being a hero isn’t about their super powers, it's about their character. And they start to understand the 6 Gifts of True Heroism from their parents.
On his way home, Billy gets mugged by a quartet of street thugs. He's fully capable of taking care of himself but before he gets the chance, Beast Boy swoops in and saves him. He is awed by Beast Boy despite being his unknown senior and quickly finds out they have more in common than he ever thought. In Billy's crappy apartment, they get close, very close very fast.
La Liga de la Justicia y el Equipo sabía que en algún momento sus identidades serían reveladas, el secreto no se lo llevarían a la tumba. Sin duda, todos dedicaron en algún momento un par de pensamientos a lo que sucedería si la verdad se supiese, pero a ninguno se le ocurrió pensar que su talón de Aquiles provendría de su mayor fuente de confianza: un miembro de la Bati Familia.
