"Sam, stop!"
Ruby's voice rings through the chapel harshly, and Sam can almost see the syllables trapped at the bottom of her throat as he shifts his gaze to her distraught expression. Lilith shouts violently at him, her voice growing coarser with every word.
"You turned yourself into a freak, a monster - and now you're not gonna bite? I'm sorry, but that is honestly adorable."
She spits at Ruby, who clenches her fists until her nails dig into her sweating palms.
"And you? You belong to me! You are mine, Ruby, you stupid bitch!"
Sam's face contorts into confusion, and his hand finds itself on Ruby's arm, begging for an answer and pulling her away from the altar.
"Lilith…is the final seal. Killing her…would set Lucifer free," she says, tears restrained behind her eyes. Sam clenches his teeth, welling up with anger.
"You bitch! You lying bitch!" Sam screams, ignoring the pounding of Dean's fists on the door behind them. He thrusts his hands at her, but drops to the floor instead, weakened. Lilith laughs maniacally, and Ruby glares at her for a short moment before crouching down next to Sam.
"And it is written that the first demon shall be the last seal…" Ruby quotes, helping him up even as he shoves her away.
"You don't even know how hard this was! All the demons out for my head, and no one knew! Not even Alastair knew - only Lilith! I'm sure you're a little angry right now, but-"
"Come on, bitch!" Lilith laments. "This plan's been around for nearly as long as you have; don't try to convince me that you're giving up eternal glory just because your little boyfriend's gotten hurt!"
Ruby flies into a blind rage.
"Shut up, you stupid slut!" she screams, and hurls herself towards the other woman, whom she impales violently on a candlestick. Lilith continues to convulse for a minute, her body glowing and flickering before it eventually falls limp. Ruby's eyes flick back and forth into blackness as she realises what's happened.
"No, no, no," she mutters, louder with each exclamation until she begins shrieking. Sam, suspended now on the edge of a pew, tries to maneouvre over to her, but she weakly orders him to stay back, and collapses at the side of Lilith's body.
The door at the back bursts open and Dean rushes over to Sam.
"I fought so hard to make her think I was doing what she told me…I wasn't going to do it. I wasn't going to kill her. I wasn't going to set him free. This wasn't supposed to-"
"What the hell just happened?" Dean whispers.
"I have no idea," Sam replies, clutching his hand. Ruby notices Dean and shoves herself up from the floor, keeping her eyes trained to Lilith's face.
"She was supposed to live long enough to see me betray her," she cries out, to no one in particular, though she hopes that Dean is too busy worrying about Sam to hear.
"Excuse me?" Dean sneers, and while Sam can see the building fight he isn't sure whose side to take. "You don't honestly expect me to think that you're changing sides after lying to us for so long? You saved our lives just so your little plan-!"
"Up until today you had no idea I'd lied to you in the first place, Dean!"
"Not helping, Ruby," Sam groans, and she looks at him as though all hope has been drained from her. She feigns a cruel grin.
"I was the best of those sons of bitches! The most loyal!" she says forcefully, but then devolves into a figure more demure.
"And now-"
"Now what?" growls Dean. She holds her head back up.
"And now I'm better."
A brilliant white light shoots up from the centre of the room and the convent begins to tremble.
"He's coming," she whimpers, suddenly overcome with fear. All colour fades from her skin and her breath hastens. She walks, trembling visibly, over to the brothers.
"Sam, I'm sorry. I'm so sorry. I thought - I thought I was going to go along with it, but- but I can't...Sam, I-"
A flash of white light catches them slightly off guard, and seconds later they occupy three consecutive seats on a plane.
"What the hell?" grumbles Dean.
"I don't know," Sam says quizzically, and he begins to postulate, but is interrupted by the pilot on the intercom.
"Folks, quick word from the flight deck. We're just passing over Ilchester…"
"Ilchester? Weren't we just there?" Dean queries, following Ruby's gaze to the rooftop of the convent, but just as Ruby's finger points Sam to the view, a column of light shoots into the sky from that very place.
"Holy crap!" is the universal declaration as the plane is knocked off course and people are thrown about the plane. Sam instinctively strings the first oxygen mask he grabs around Ruby's head, but a moment later yanks it away, pressing her back into the seat with a kiss like no other.
