A whirring sound came from the top flat of 221B Baker Street as the TARDIS appeared in Sherlock's tiny kitchen. Amy ran out to find Sherlock lying down; obviously in his mind palace. However he was not alone. Molly Hooper was sitting next to him where she was previously reading over case files scattered across his desk before she jumped at the sound of the TARDIS.
"Amy! Doctor! You startled me!" said the small pathologist. "Hello Molly! Still with this sociopath I see," the Doctor chuckled. Sherlock was still deep in his mind palace, ignoring the fact that the TARDIS had landed in his own kitchen. "I was just helping Sherlock with some very curious cases." "Really? Mind if I take a peek?!" the Doctor said happily. "I guess so."
"Wait!" Amy accidently shouted. "Er...sorry. But Doctor that's not why we came. Remember?" "Yes. Of course. Molly, did Dean Winchester come by here during the last few -" "Three days ago," Sherlock unexpectedly mumbled. "Judging by Amy's childish ecstasy and the Doctor's random appearance at," Sherlock stopped to look at his clock, "1:30 in the morning I assume that neither of you knew he was alive."
Amy rolled her eyes. Sorry, Molly mouthed. "Why did he come by here?" the Doctor continued. Molly waited to see if Sherlock would answer but knew he had already stepped back into his mind palace. "Well," she started, "he came by to see if we were working on any strange cases." Amy and the Doctor looked at each other with confused looks. "Yes, he came by asking if we knew anything about something called a Krillitane." The Doctor's face went from happiness to seriousness in less than a second. He walked up to Molly. "What did you tell him?" "The only things we knew," Molly responded. "They have a wingspan of about 5 feet, very large teeth, and they like to feed on intelligent people." "Those are Krillitanes alright," the Doctor replied, facing a window.
"So, did he say where he was going when he left?" Amy asked impatiently. "Actually, he said he was going back to America. To Tornado Alley," Molly answered. "What's Tornado Alley?" asked Amy. The Doctor answered, still staring out the window, "It's a few states in the very center of the United States where tornados form quite often. And I know exactly why he's going there. Come along Pond, I'll explain on the way." He grabbed Amy's hand and quickly walked back into the TARDIS.
"Wait, Doctor, we don't even know where he is." She freed herself from his grip. "Now if you'll excuse me, I have to get some directions," Amy said, walking into Sherlock's room and closing the door. "What's she doing? asked Molly. "Praying," the Doctor and Sherlock spoke at the same time. "Obviously," Sherlock added.
Amy turned on a small lamp by his bed and got down on her knees, hands folded. "Castiel," Amy started, "it's me. Amy. Please come. It's...it's about Dean. He's not dead. You probably already know that but..." All of a sudden she heard the beat of wings behind her. She stood up and quickly spun around. There stood the trench-coated angel.
"Amelia," he said in a gravelled voice, "how do you know about Dean?" "Donna told me." Castiel gave her a monotoned look. "I can't tell you where he is." "Please Cas. I love him. I need to be with him." "I know. And he cares for you as well. But he has given me orders not to tell you where he is if you ever did find out."
"What?" Amy asked. "Why?" "Because he loves you," Castiel answered. "He doesn't want to see you get hurt." "Not being next to him hurts," she said sternly. "Tell me where he is, Cas." "I can't." "Castiel!" Amy's voice rose. "I'm begging you. Please. This is my choice."
"He will be angry," Castiel replied. A long, awkward silence fell through the air. Castiel hung his head. "He is in Kansas, heading for Oklahoma..." the angel mumbled sadly, "please tell him to forgive me." With that, he disappeared and Amy ran out of the room.
"Put on your Stetson Doctor. We're going to America." This time Amy pulled the Doctor into the TARDIS, closing the door behind her. "Oh," she popped her head back out of the blue box, "thank you Molly. It...it meant a lot." "You're most welcome and good luck!" Molly said with a smile on her face.
