What if A&E do a Star Wars thing and recreate "Return of the Jedi" when the emperor is trying to kill Luke and Vader snaps out of being evil because his love for his son is stronger than the darkness, saves him and kills the the emperor but then dies in the process? Then Luke tells his father "I need to save you" and Vader says "You already have". All this but CS style! Uuuugggh! and Epic!!!
That was honestly my first thought when I saw that promo scene. Just IMAGINE it.
Emma caught in the grip of the Dark One, choking, desperate, looking at Killian in mute appeal. He just stands by passively, face unreadable, eyes carefully blank as he watches. But inside him, a storm is raging, anger against love, grief against rage, he’s trying not to care but he does.
It seeps out through the cracks in his heart, and slowly builds up inside of him, until he can’t deny it anymore---
And he rushes forward, raises Excalibur, and plunges it into Nimue’s chest.
It seals her fate, and his. The Darkness rears up, mortally wounded, surging out of Killian and out of Emma, too. Nimue staggers, and falls. She is taken down to the underworld, and he knows that he must follow.
Emma falls to her knees beside him, shaking her head, tears on her face. “No, no. I’ll save you.”
A smile. “You already... have. You were right about me, love. Tell them... you were right.”
And Killian Jones once again breathes his last. Emma stays frozen for the space of three heartbeats, and by the third, she knows what she must do. Once again the Savior, she knows her power, and she knows her next step. She takes one more look at the still form of the man who just saved her, and sets her jaw.
