Now that Daniel (Aden Young) has confessed to killing Hanna, Amantha (Abigail Spencer) finds her entire life uprooted when Rectifyreturns.

After nearly two decades of standing by Daniel's side and fighting for his exoneration, the plea deal feels like a betrayal to Amantha, who not only loses faith in her brother, but also her only directing force in life.

"I think sometimes he believes he did [it] and sometimes he doesn't. I truly don't think he knows," Jon (Luke Kirby) says, before adding that Daniel still needs her.

"You can't help those you won't help themselves," Amantha snaps.
