Sherlock meets The Flash and Arrow

Chapter 19

John

Cisco answers his phone, "Let me put you on speaker."

Mycroft's voice crackles, "Are you seeing this too?"

"If by this, you mean Trickster, then yes." Everyone crowds around Cisco, except Felicity who pulls her tablet out—presumably to trace Trickster's signal.

Sherlock starts tapping a phone. It's not his. He must've pickpocketed someone else, probably Diggle. He tries a few combinations and the phone unlocks. He pales noticeably and shows me the message flashing on the screen.

Moriarty. Slightly dressed up with some face paint and a few years older, but definitely him.

I put my face in my hands.

Sherlock says quietly, "If there's a Mycroft, it stands to reason that there's a doppelganger of everyone in our world in this world."

In a shallow voice, I choke out, "So something's different. In this world...you haven't killed yourself and Moriarty to save me. You didn't jump..." My throat tightens, but I force the last word out, "...yet."

Sherlock winces and looks away. Once again, I'm struck by how human he actually is. He turns to Cisco's phone and says, quietly, "Hello, brother mine."

Mycroft grits his teeth. "Now is not the time for jokes and games. And it is never the time to taunt me with my stillborn brother."

I gasp. "Stillborn! That explains so much...Why Moriarty isn't dead yet, why no one has heard of you...Wait. What does that mean about my doppelganger? If you don't exist, I wouldn't be able to stay in London..." I trail off, lost in my own thoughts.

Sherlock puts his hands in his thinking position. Suddenly, he says, "Your parents met in America."

Mycroft has a note of deadly calm in his voice as he replies, "Felicity. Did you hack my personal files? Because this isn't funny anymore."

Felicity gulps. "No no no...Well, I hacked your files, yes, but I didn't get the America thing from them."

Mycroft's voice goes icy. "Then how did you know?"

Sherlock says, quietly, "I know because they're my parents too.."

Mycroft gasps. Quietly, he asks, "Sherlock?"

Oliver

Cisco says, "We have some interdimensional travelers...One of them is your brother."

I sigh and walk over to Felicity. "Got anything?"

"Nope. He's scrambled his signal amazingly well. He'd have to have helpers."

I frown. "Guys, hate to break up the wonderful reunion, but we do have a world to save. Got any idea why Trickster came back?"

Sherlock bows his head. "Someone bad knows I'm here. Moriarty always did love to play games with me."

Then the message abruptly changes from its monotonous Did you miss me? Trickster's face comes on, and he says, "I always had a special thing for bombs, but today it'll have to be fire." The camera shifts to Vandal Savage, who flickers a flame in his palm. "If you don't give me Sherlock Holmes, on top of Bart's Hospital, in three minutes, I'll burn this city to the ground." Then the screen cuts to black.
