The song here is "Field of Innocence" by Evanescence
Field of Innocence
Castiel left Heaven and stood in a random empty field that stretch out to the horizon in nearly all directions, except for the trees in the North. It was a well isolated place to meet an Archangel that didn't want to be seen.
He had to summon Gabriel and then he stood in place, patiently waiting. While he waited, he thought of Micah and his plans to eliminate hybrids. If he had his sights set on Clara, it was no wonder he went "missing". But why disguise him as Metatron and have him return to the cells in Heaven? He would imagine killing Micah to be more of Clara's style.
However, he wasn't there to get the details of the event; he was here to see if Gabriel could let Micah go. He may have had a horrible idea, but Micah wasn't an angel that deserved to spend eternity in a cell. Why Gabriel helped Clara was beyond him; she didn't need anyone's help. He could have helped Heaven instead. No wonder the angels were angry with him when he left; if they knew of his treachery… Castiel didn't want to think of it. It could start a civil war within Heaven and then Hell could just sit back and watch their adversaries fall to ruins.
"Oh, you again." said that familiar voice. When Castiel turned around, Gabriel had his arms crossed over his chest and he seemed less than pleased. It wasn't really Gabriel, but a projection of himself. Obviously, staying I Hell was more important. "Don't you have something better to do?" he asked and when Castiel approached, his narrowed his eyes. "This better not be about Metatron." he said and Castiel stopped with a slight expression of confusion.
"What have you done to Micah?" he asked and Gabriel now seemed confused.
"What do you mean?" he asked with sincerity, but Castiel knew he was playing stupid. "Didn't you hear? He's missing." He added and Castiel frowned.
"I saw him, Gabriel. You disguised him as Metatron." Castiel said and then Gabriel gave that dark smirk.
"If you knew, then why did you ask?" he said and Castiel approached with irritation in his eyes.
"I am in no mood for your games. Micah is a good angel." he said, but before he could continue, Gabriel raised his hand and his smirk fell away.
"He thought killing hybrids was a good idea. He was especially wrong with Clara." He replied and Castiel was about to say something, but Gabriel cut him off. "Am I the only one that can see she's not the monster they believe her to be? She's part human; she made a choice, but that doesn't mean we can kill her. She made the choice with free will and Dad was all about that. So are you, may I remind you, Mr. Team Free Will." He added and Castiel frowned.
"I am not condoning his actions, but he does not deserve to be in that cell until the end of days." He replied, but Gabriel seemed bored.
"It wasn't the first time he tried to kill her, Castiel." Gabriel said and his missionary friend remained silent. "And he wanted to kill Keara too." He added and Castiel tried to reason, but Gabriel wouldn't let him. "Has Clara killed without purpose?" he asked and Castiel was about to answer, but Gabriel didn't give him the chance. "She kills when someone threatens her family. Did she release Lucifer? No, she contained him." he added and Castiel's face fell, but Gabriel didn't bother explaining.
"Gabriel –" Castiel began, but the Archangel waved him off.
"I'm not helping Micah." Gabriel said and Castiel remained silent. "Thanks for the visit, but if I see you again, it'll be too soon." He added and vanished.
Castiel stood in place, uncertain of what to make of this. Gabriel seemed irritated and he made it clear there would be no mercy for Micah.
Castiel glanced up at the sky, thinking of Micah. He could just turn his back, but that wasn't who he is. Micah may have exiled him, giving him the reason to walk away and do nothing, but that wasn't an excuse to leave him to rot in that cell as Metatron. The crimes that Metatron committed weren't Micah's to pay.
If Gabriel wasn't going to help, than it was left up to Castiel; he'd have to convince the angels that Metatron was Micah and, somehow, he'd have to undo Gabriel's twisted tricks. As Castiel walked out of the field, he realized that the two would be nearly impossible. The angels weren't very good at going beyond the point of "seeing is believing" and he might need Anne to help him free Micah. Gabriel didn't work with magic and if Anne couldn't undo what he did, there was no one else.
Perhaps only Anne's child, but how long would they have to wait until the child is old enough to know how to use its powers?
Castiel shook his head, knowing that that idea wasn't useful. He needed something immediate and he wasn't exactly so sure that he could keep his promise to Micah.
He stopped and stayed in place, glancing up at the sky one more time. He knew he probably couldn't have kept his promise and now, he was right.
"Forgive me Micah, I don't believe I can help after all." He said and guilt began building up within him again. There was nothing he could do right. Why didn't he just surrender his grace and live like a useless human already? He would probably be better at doing that.
He decided to head back to the Men of Letters bunker, still foolishly holding onto some hope that he could help Micah, despite his doubts.
