John bit his lip and watched with wide eyes. Sherlock finished the formula and grimanced.

"Tastes like grape."

"I love grape." The man smiled. "Tell the doctor G.B. said hi." And he jumped off the window. John ran towards Sherlock and started checking for his everything- pulse, temperature, etc.

"How do you feel?" John asked.

"Dizzy like what you felt in the hallway maybe because he was controlling me but it started when he let me go so it couldn't have been the formula."

"Then do you have any feeling associated with the formula?"

Sherlock pursed his lips "There's a bad taste of grape left in my mouth. I'm not a big fan of grapes. Did you remember when-"

Sherlock fell on the floor and hugged his stomach. "Sherlock!" John called. "What's wrong, what do you feel?"

"Like my insides are breaking apart" Sherlock heaved. Beads of sweat appeared on his forehead and his eyes were shut.

Through Sherlock's gasps of air and screams, John heard the tardis just outside the hall. The Doctor would know what to do, John thought. "I'll be right back, Sherlock. The Doctor is here."

As John stood up, Sherlock grabbed his hand. "D-don't leave me… please." Sherlock whispered. His eyes were fluttering and his hand was wet with sweat. John felt sorry for him. It should have been him who drank the formula and not him. "The Doctor is here. He could help, remember him?"

"Wibbly wobbly ,timey wimey." Sherlock smiled, recalling his last adventure with The Doctor.

"Wibbly wobbly, timey wimey." John confirmed. He squeezed Sherlock's hand before he ran to the corridor.

The Tardis took up the entire corridor so he couldn't see the other side. The doors of the tardis burst open, revealing a smiling Doctor, a tired Sam, a time-sick Dean, and a Castiel.

"Eyy! John Watson! He-lo, Doctor! Always wanted to call someone else doctor to see how it feels." The Doctor clasped John's hand and hugged him with his other arm. "I've brought Sam and Dean too! Remember them?"

"Yes, how can I forget?" John asked, shaking Sam and Dean's hands "Sherlock and I nearly died."

"haha, yes…" The Doctor laughed uncomfortably. "Well… What do you think of my new face?"

"You regenerated then?"

"mhmm! What do you think, do you like my bow tie?"

"Not really."

"Well, bow ties are cool."

"Anyway, Doctor, Sherlock needs help."

"Yes I know, I always thought his lack of emotions was a sign of problems at home."

"Not that kind of help. As in your help. A psychopath called G.B. was messing with us to get your attention. Sherlock drank something and now he's sick. Is he dying?"

"No, not really. It's ok, everything's fine. Gavin Brody is actually a human and he's part of this cult that's sworn to protect the course of time. They make sure things go according to plan which means that they know past, present, and future. He can't tell exactly what's gonna happen to help us but he can give hints. When he's near then something is coming. Something big. Where's Sherlock?"

"Down the hall." John said, leading them to the lab.

When they reached the door, Sherlock was standing with his back towards him. His hair was longer and he was thinner.

"Sherlock?" John asked.

"John- what's wrong with my voice?!" He turned around and faced them. The doctor was there with the Winchesters and Castiel. Their mouths fell open- even Castiel who's eyes grew wider. The Doctor's mouth opened too but the sides curved into the slightest smile.

"What's wrong with my face. Hello doctor, what's with the bowtie? Ahem, this voice is strange." Sherlock touched his neck and suddenly grabbed it. "Why is my neck so smooth? What's wrong with me?! Answer me honestly! John, Dean."

"You're female Sherlock!" Dean laughed "You're femlock! No, Sherlock… Charlotte!"

"What?!" Sherlock asked. He ran to the half drained sink and stared at his reflection. His hair was longer so his bangs covered his right brow. His eyebrows were thinner and he had thinner lips and a paler completion. He still had his cheekbones but he had sharp eyes and long eyelashes. His (or her. I think I'll go with her now) her hair reached a few inches below her shoulders. It was wavy until it curled at the end.

"You don't look bad." Sam admitted.

"But I'm a girl!" Sherlock squeaked in her higher voice.

"Amazing." The Doctor said "How is that possible? The chemical compounds…"

"He made me drink something." Sherlock said. "The G.B. man."

"Gavin? Really? Stick out your tongue."

Sherlock stuck out her tongue and The Doctor took out a popsicle and pressed it on Sherlock's tongue. When he took it out, there was a deep purple stain running through half of the stick.

"I'll keep this for analysis." The Doctor muttered, running to the tardis.

"He could have just killed me." Sherlock moaned.

"No, he couldn't have" The Doctor said, stopping in his tracks and facing them "He did this for a reason. Small things might be insignificant but they're clues. Gavin is smart. He knows how to hide clues. He hides them very well so that the cult won't accuse him of telling us the future. Something big is coming. Something really big and we don't know what and all we've got is this purple popsicle stick."
