"You want Cas to erase everyone's memories?" Dean asked, laughing, thinking that was the stupidest and most cowardly way to deal with the problem. The Doctor gave him a trying look as Sam sided with Dean.
"Look, frankly, I don't want to kill some innocent person to get to Raziel, and I will not allow anyone to kill you if you let Raziel win. This way, Sherlock will be safe and he can't use anyone else to get to Sherlock," the Doctor hissed as John nodded.
"This seems the simplest way out," John informed as Sherlock folded his arms in the corner, wanting out of this nightmare.
"I don't care. It's cowardly!" Dean shouted, angry.
"Cas has already agreed to it!" the Doctor informed loudly as Cas nodded once.
"Dean, you have to understand the gravity of the situation," Cas whispered.
"Oh, boohoo! Get over it. We can take him. I've killed more powerful things that Raziel!" Dean informed as Amy raised her eyebrows.
"I don't care what you've killed! Raziel needs a host and I will not allow you to kill someone that thought they were following their religion!" the Doctor shouted as Rory rolled his eyes.
"Why are we arguing? I choose life over getting rid of Raziel. I'll let the other angels or whatever deal with him!" Rory announced, thinking this whole argument was stupid. Dean glared at the man, but Rory stood his ground.
"This isn't a game!" Dean shouted as Sam tried to calm him down. "Shut up, Sam!"
"Dean!" Sam snapped, equally angry. "You are being ridiculous. I agree this is a coward's way out, we have to remember what the main objective is. And it has nothing to do with Raziel."
"I don't care," Dean hissed as Sam just stared at him.
"Really? So, all this work we've done, the family business, as you call it, is for nothing? All you care about is this one angel?"
"No!"
"Then what is your problem? We forget this ever happened and we go one stopping the apocalypse! What is the down side? No one will remember!" Sam yelled as Dean stared at him, not backing down. "There are more important things at stake, Dean."
"Fine, whatever!" Dean shouted, very irritated. The Doctor took a deep breath, giving a thankful look toward Sam. Dean rubbed his brow, feeling that this was a stupid idea, even if it was the simplest solution.
"And none of us will remember?" John asked, his arms sternly crossed. He agreed with both Dean and the Doctor. Even it was the most logical solution, for some reason, it seemed risky for some reason. The Doctor nodded before Cas could say anything.
"Of course," the Doctor whispered with a small smile before John took a sharp breath.
"And this will fix everything?"
"Yes."
"Will I remember any of you other than Sherlock?" John questioned, rather liking the group. The Doctor bit his lip and shook his head.
"Unfortunately, no, you won't. It will erase your memory since the incident at the secret laboratory. Like we never entered your universe. For Sam and Dean, they won't even remember getting on the plane or even getting a call from me," the Doctor answered thoroughly before Dean straightened and faced the Doctor.
"Will Sam and I remember you? I mean, you're not going to erase your existence from our heads, are you?" Dean hissed, thinking that was pushing it too far.
"We have to be thorough, Dean, and I might invoke the memories of this event," the Doctor informed as Dean shook his head.
"But I am not in danger! Sherlock is!"
"Can you imagine if Raziel found out you remembered? He would lure you right back here to get Sherlock to remember. No, we have to make sure that we are all safe," the Doctor whispered harshly.
"This is insane!" Dean accused, growing angry. The Doctor just sighed as Sam said nothing. "Doctor, Sam and I are losing friends fast. We can't lose you, too."
"You won't even know that I was here," the Doctor chuckled lightly, understanding how Dean felt. "I won't even know that I've been here."
"This is bullshit!" Dean screamed before turning away. The Doctor watched as Dean started to self destruct again. Sam watched from afar, not sure how to deal with the situation. Sherlock bit his lip, taking no side in the matter. He saw that the logical way was to get rid of all the knowledge, as much as he hated to admit. This was the best option that they had.
"Cas, just do it," Amy whispered before Dean flipped around and stuck a finger towards Cas's face.
"Don't you dare," Dean warned as the angel sighed.
"Dean," Cas began.
"No, Cas, don't you dare," Dean repeated before Cas took a step toward him. Dean stepped back hastily with a warning look. "Don't you come near me."
"Dean, we have to do this," Cas informed, unemotional. Dean shook his head, batting Cas's hand away. Cas lowered his hand before appearing behind Dean, wiping his memory with a touch. Dean collapsed onto the ground, unconscious. The barn went silent as Cas looked up.
"Will he..." Sam started as the angel nodded.
"He will be fine," Cas reassured as Sam took a deep breath. Cas touched Sam's forehead before he went limp as well. Sherlock watched, wondering how Cas was able to do this. Cas placed Sam next to Dean and straightened.
"And it doesn't hurt?" John asked before Sherlock stood up, facing the angel.
"Of course not," the Doctor answered, hating all of these questions. John nodded as Sherlock studied the angel.
"And I won't remember any of this?" Sherlock inquired, thinking of all that he had learned. That there were such things as aliens, angels, and monsters. That things did go bump in the night, which science could not begin to answer. Cas shook his head, raising his hand. Sherlock flinched, but allowed his memories to be taken away from him. He didn't want all this supernatural information in his head. It was useless to him and made him question too much about what he thought he knew. It would be easier if it was all gone. Cas touched Sherlock's forehead before he collapsed as well. This time, Cas caught him and propped him up against the wall. John took a deep breath and looked at the angel, frightened of him. Amy and Rory went next, leaving only John and the Doctor.
"What about everything we've been through? It seems cruel to take that all away," John murmured, his arms still crossed. The Doctor shrugged.
"It's nothing new," he whispered, remembering Donna. John glanced up at the Doctor, shaking his head.
"You have seen so much," John whispered, almost in awe of the Doctor. "I am so sorry."
"For what?" the Doctor nearly laughed, making John smile weakly.
"I know a war veteran when I see one, Doctor, but I figured you didn't want to talk about it," John informed, surprising the Doctor. "The way you look at things, at people. It can be difficult."
"Yes, it can be," the Doctor answered, not looking at Watson. John sighed as Cas turned toward him.
"Just remember that there is something worth fighting for, Doctor," John informed, puzzling the timelord as he went to the angel.
"Of course there is," the Doctor replied as John ducked his head and smiled.
"Just don't forget it," John whispered before Cas tapped his head, sending him into a sleep like the others. Cas looked up at the Doctor, who took a deep breath.
"Thank you, Cas," the Doctor whispered as the angel nodded.
"I will take the Winchesters back to their home," Cas informed, walking over toward them.
"Hey, could you put the Ponds, Sherlock, and John by the TARDIS?" the Doctor asked as the angel nodded, disappearing with them. The Doctor took a deep breath, but before he could turn toward the door, Cas scooped him up and placed him next to the TARDIS, disoriented. "Thanks, Cas. I needed that."
"You're welcome," Cas replied, letting the sarcasm go over his head. The Doctor took a deep breath.
"Thanks for your help," the Doctor whispered as Cas nodded.
"It was nice to see you, Doctor," Cas informed before disappearing. The Doctor smiled and looked at the stars. He hoped that somewhere, Raziel was still looking for them. Still hopeful and snarky. Waiting for the disappointment to come and shock him. He opened the TARDIS door and dragged them into the TARDIS.
Within a half an hour, he was able to drop off Sherlock and John, placing them on their beds in their rooms, as if no time had passed. The Doctor nodded once he got Sherlock on the covers, taking a deep breath. He was sad to let Sherlock go, never to see him, or John again. He had felt so guilty about leaving him the first time, but this time, he guessed, he had a friend with him. For now.
The Doctor jumped back in his machine, leaving his friends again. He saw Amy and Rory, still unconscious, on the bench. He took a deep breath, remembering what Cas had told him about Sherlock. He turned the dials and went into Sherlock's near future, where only months had passed since the incident. Cas told the Doctor that he would meet him there for the last time. That he needed to see something. Something that would make him feel better about leaving him with John. He also said that the Winchesters would be there, for they needed more information on a case that they would be working on. Nothing of extreme importance, Cas reassured and the Doctor just nodded. He looked at the monitor, his destination, before pulling the lever to send them through time once again.
