Sherlock Oneshots (Mystrade/Johnlock/Mormor)

His Last Vow - Johnlock/Mystrade

3rd Person P.O.V

"Can you just... can you just leave, please?"

John's voice was shaking, and he could barely hear what he'd said. Mary nodded. She understood.

Her husband had just found out that she was a murderer that had shot his best friend. She understood that he needed space. She just hoped that he wouldn't leave her. But, she knew John. She knew how loyal and dedicated he was. She was pregnant, and she was certainly going to use that as an advantage.

She left 221B, and went back to The Watson's flat. That was where she stayed for the night. But, her husband didn't go back home.

Back at Baker Street, John and Sherlock were sitting on their couch together. John was crying, and Sherlock was trying (and sort of failing) to comfort his best friend.

"Why does this always happen to me?" John whispered. Sherlock shrugged, and placed his arm gingerly around his friend's shoulders.

"I don't know, John. I don't know. All I know is that you don't deserve this. You deserve someone who won't lie to you."

"Seems like I can't find that."

"You will."

A moment of silence passed before John spoke again.

"Do you know what I said to your grave right after you were buried?"

"I was there."

They both chuckled, and John shifted closer to Sherlock.

"I said that no one could ever convince me that you ever told me a lie."

"Oh. I remember now."

They both laughed again, and John took that opportunity to move even closer. He kept trying to distract Sherlock, just to be able to get closer to his best friend. John wasn't entirely sure what his end game was. He just wanted to be as close to Sherlock as possible.

"You'll never lie to me, will you?"

"I wouldn't dare."

"You'll never leave me again, will you?"

Sherlock finally noticed the close proximity, and decided to rest his head on top of John's, and tighten his grip around his shoulders.

"Never."

"Can I stay here for a bit?" Sherlock noticed the nervousness in John's voice, and that made him laugh.

"You can stay here as long as you'd like. You're always welcome here." John slowly wrapped his arm around Sherlock's waist, which made both of their pulses quicken.

"Thank you..."

"What about Mary?"

"She shot you. I don't think I could ever look at her the same way again."

"She didn't kill me. She did that on purpose."

"I don't care. She hurt you."

"She's carrying your child-"

"I don't know her!" John yelled, jumping up from the couch. "I don't even know her real name! But... I still fucking love her! Why do I still love her? What is wrong with me?"

"John, there is nothing wrong with you. Of course you still love her. You married her. Yes, she was lying to you. But, you still fell in love with each other. Trust me, she loves you just as much as you love her."

"I don't know what to do. I know what it's like to grow up without a mum and with an absent father, and I don't want that for my kid. Maybe... maybe we could- oh god, I don't know! I can't see a way that this can work! I know that, whatever happens, I can't be happy."
