221B Baker St.
Sherlock sat in his chair staring at John. "So, what are we going to do about Moriarty?" John asked, finally breaking the silence. "Honestly, I don't know" Sherlock replied, waving off as she began to approach the two. "Do you think…"John was cut off by a strange noise. The two looked outside to see a man wearing a red fez step out of a blue police box.
Soon, a woman stepped out behind him. The woman had blonde, curly hair and was wearing a white shirt with what looked like a black belt holding a gun. She had brown leggings and black boots. The two were most certainly not from here, and as Sherlock observed, there was going to be some trouble very soon. "Something that has to do with that man is going to lead us all to trouble, and it may involve Moriarty." Sherlock said after examining the mysterious duo.
As walked in, Sherlock and John ran past in hopes that the two weren't gone.
As they ran down the street into the sea of people, they gave up, knowing that either the danger would come first, or they will come back to the mysterious blue box.
