The Supernatural sign of the 7 heroes (SPNxSherlockxHOO)

Come on Nico!

Nico POV
"Any idea why Chiron wants to see us?" I asked, looking up at Will. He looked down at me and grinned,
"probably to now change the rules about two boys being able to be in a cabin alone" I rolled my eyes at my boyfriend.
"Shut up Solace" he laughed and grabbed my hand. It had been three months since the war and everything was looking up. On the third day of my stay at the infirmary Will declared his loved and we kissed, much to the delight of the Aphrodite Cabin spying on us. And no Will and I just kissed, we were not doing anything inappropriate, not that anyone cared what we said
. "Nico what are you thinking about?" WIll asked. I looked away, my face turning bright red.
"Nothing" Will laughed and gave me a big hug.
"If you say nothing then i am assuming you're imagining me shirtless." He murmured. I pulled out of his hug
, "In your dreams sunshine" He laughed and gave me a peck on the cheek. We made our way up to the house
. "Will, Nico" Chiron greeted, in his wheelchair.
"Hello Chiron" Will greeted. I looked at him curiously, he seemed tired and an aura of death surrounded him.
"I need your help" Chiron said gravely
"Anything" Will stated.
"You see an empousa has been terrorizing London"
"So?" I interjected. He shot me a look before continuing
. "This usually wouldn't concern us but a detective can see through the mist,"
"Sorry, but why does this concern us?" I asked, getting annoyed, I just wanted to not almost die again.
"He is unlike anything we have encountered. Incredibly smart and dangerous, I need you and Will to meet him and tell him the truth."
"Why do we want a mortal's help?"
"Because him and his partner are a paradox to say the least. If he found out about demigods then I believe he could help us"
"Nico and I will go see the Oracle." Will said dragging me upstairs.
"Hey Will and Nico" Rachel said when we saw her.
"Hey Rachel, mind giving us a prophecy?" Will asked grinning. The room filled with smoke and Rachel started chanting.
"Through darkness and light
There comes a great fright
A pair and trio you will meet
At 221B Baker street
Go ahead and solve the crimes
Before it's too late and you are out of time
Serve the god and take the test
Or else both you and them will  forever rest"
She then collapsed on her bed. Will rushed over and started checking on her. I slid back downstairs to Chiron.
"Judging by your face, its A quest." Chiron said. I nodded as Will rushed downstairs
."We will go" Will said shooting Me a look. I glared but said nothing.
"Thank you, their names are Sherlock Holmes and Doctor John Watson. Their address is 221B Baker Street. You will leave tomorrow morning, Nico will shadow travel."
Will nodded and grabbed my arm leading me to Hades Cabin.
"Are you insane?" I yelled.
"Nico, it's a quest! Not only that but I have always wanted to see London."
"And a murderous empousa!" I added.
"Nico please" Will begged. I glared at his blond curls wrapped around his pleading blue eyes.
"Fine but you owe me" I grumbled. Will squealed and gave me a passionate kiss before running out to pack. I sighed and threw my stuff into a black bag and flopped down on the bed. What were we getting into?
