"Reunion" is the pilot and first episode of the American television series Runaways, based on Marvel Comics superhero team of the same name.

Nico Minoru, a goth, is forbidden to enter Amy's room by her strict mother Tina, while her father Robert tries to console her.

Chase Stein, an athlete who possess a hidden intellect, is berated by his father, Victor, due to getting a C in Spanish while his mother, Janet, looks on.

At school, Alex decides to invite his former friends over to his house so they can bond again, but they all either ignore or flat out refuse due to their differing opinions and personalities.

Karolina is teased by the other classmates who call her brainwashed due to her connection to the church, but manages to find solace in Nico who ignores Alex when he asks her directly to come hang out.

At dance tryouts, Molly begins to suffer from stomach cramps and goes to the nurse's office thinking it is puberty, only to learn that she has super strength.

She removes her Gibborim bracelet for the first time (she claims that she can't remember ever taking it off) and begins to glow rainbow colors only to pass out.

Chase, Gert, Molly, Karolina and Nico arrive at Alex's house and the six confront each other's current behavior as well as Amy's unexpected death (the incident that broke them up).
