A couple weeks later, just after November had given way to December, he found her.
Sofiel had been walking a narrow path up an unnamed mountain in the Himalayas, to one of her secret resting spots, when she heard a rustling sound from behind her that did not coincide with the sound of the whirling, freezing, wind that was a near constant in the Himalayan winter.
She whipped around in her spot to peer behind her, but could not see far through the blinding snowfall with her vessel's meager eyes.
Then out of nowhere, he pounced on her, knocking her into the snowy gray rock wall that was to her left.
Sofiel winced as her shoulder was sliced by a sharp, jutting piece of the mountainside, but in an instant the pain and the tiny flesh wound were gone.
Castiel pinned Sofiel to the rock with one arm and stared at her with cold, furious eyes.
"Did you really think I wouldn't be able to find you if you minimized your use of your powers?" Castiel chuckled. "Think again."
"Castiel, please don't," Sofiel begged as Castiel raised an angel sword up to her chest level. "I'm trying to help you. Remember who you used to be."
After she spoke, there was a flicker of regret in Castiel's dark blue eyes, one that a normal human would not have been able to catch, before he lined the sword up with her vessel's heart.
"I am not HIM anymore. No more am I weak. You sided with Raphael in the war. I will show you no mercy."
Just as Castiel was about to plunge the sword into her vessel's heart and her grace, Sofiel summoned every ounce of her strength and shoved Castiel away from her, surprising him, and sending him off the cliff. She watched as he fell and fell and fell until he disappeared from sight, on his way to the bottom of the mountain, six thousand feet below.
Knowing that even an angel could survive a fall like that, Sofiel immediately teleported away. She had to get as far away as possible before Castiel landed at the foot of the mountain, before he healed. All she could think about was getting away, but she didn't know where would be best. So, in her panic, she flew to the worst possible place she could have gone.
She flew to Bobby's, she found out where Sam and Dean were hunting several lower demons...
And she left the house to search for them...
Finding them in a warehouse just outside of Lincoln, Nebraska.
Dean and Sam had just finished battling and killing the three demons they'd been after when Sofiel appeared in front of them, seemingly breathless.
"What the hell?" Dean said, caught off guard. "Sofiel? What's going on?"
"Castiel found me in the Himalayas," Sofiel rushed. "I ran."
"You ran towards us!" Dean shouted. "Are you stupid?"
Sofiel was hit with realization and devastation. What have I done? She thought.
"Dean, if Cas is on his way, we don't have time to yell at her," Sam said, tugging on Dean's sleeve. "We have to leave, now."
Dean nodded, and the brothers turned around on their heels, ready to run for the Impala.
But they hadn't been fast enough.
Standing before them was Castiel, caked with blood and a wild look in his eyes.
"Where do you think you're going?"
A/N: I know, I know, it's a mean cliffy, but it was such a natural end point for a chapter I had to do it. I'll be posting the final chapter soon, hopefully tomorrow, if that makes any difference.
