River had never had more adrenaline in her system then when they raced to Lisa's house that day. They didn't actually go all the way though, for it seemed Vera had cut off Lucifer on the way there.
She looked different. Her hair was cut in a round style around her face and it seemed she'd lost her eye at some point, for on one side of her face was an eye patch. Vera was wearing tactical gear, blocking an attack from Lucifer.
Despite him wearing Sam's body, River knew it wasn't. Sam was still in his forgotten memories while Lucifer tried to slay Dean's loved ones.
He was distracted, his fight with Vera consuming his attention. Castiel was focused on Crowley, who'd begun to hurl after the angel teleported them. No one was paying attention to River.
She ran forward, calculating trajectory in seconds. All that was in her mind was numbers, not her surroundings.
Lucifer was caught of guard, but so was Vera. Her one eye went wide as she watched the struggle. River barely had time to think before she blacked out.
The Devil was not what River had been expecting.
They stood in a memory-Lucifer's, she believed-of a marble hall. He looked a touch scruffy, and his eyes only showed the Angel. The Vessel's soul that had once existed was gone. He wore a tee shirt under an unbuttoned shirt and jeans. He faced her for a moment and shook his head.
"Poor pitiful Raziel. This isn't even the present you."
"Why am I pitiful?" She replied as if it was her name.
"Because you continue to chase Sammael." Lucifer crossed his arms. "Years ago he swore to serve me."
"Excuse me?" River's eyes went wide. "Sam would never have-"
"I didn't say Sam. I said Sammael." Lucifer held up a hand. "You don't know all there is to know yet."
"I don't have to to know you're actions are wrong."
"He swore to serve me, whether he remembers in this life or not."
"This is the life you're trying to control and stain with blood." River retorted. "So I'd say it matters."
"You don't get it do you?" Lucifer chuckled. "What is your plan to defeat me?"
"With my brain. Once I train. Ha. I made a rhyme." River smiled as Lucifer shook his head.
"Sam and I are bound now. Unless you have a way to extract me-something I highly doubt seeing as he said yes-anything you do to me, you would do to him." He grinned. "Or more importantly, to affect me, you must commit that action against my vessel."
"You lie!" River exclaimed.
"In the mindscape? It's impossibe." Lucifer scoffed. "But fine. Don't believe me. Find another way. I dare you. But I grant you a warning." He tossed her a red gemstone which she caught clusmily. "if I unite with my bride in this form before you do, Sam's gets snuffed out and the cycle ends once and for all."
"Pardon?" River whispered. "He's died before-"
"I'm not saying if he dies." Lucifer replied. "I'm saying if I am still in his body and my bride and I become one, your precious Sam, and all of his past lives, will cease to be in an instant."
