Where the Hell Is Sebastian Moran?

Where the [bad word] is Sebastian Moran? 
Where the [bad word] is Moriarty's right hand man? 
Is he busy? Can you call him? Is he out there shooting tigers? 
Hidden behind the scenes? Starting jokes? Flaming the fires? 
Where the [bad word] are you, Moran...

We always assume it's him behind the gun 
Which seems a bit silly but really we're at our wits end

Irene? John's sniper? Now it's hurting my head 
At this point I'm starting to suspect Anderson
