OMG Moriarty you are adorable. I can't handle how amazing you are.<--I can imagine him saying "I will break you.like a kit-kat bar"
Moriarty might have been eleven when he killed his first person, but Sherlock was eight when he tried to solve said crime.>>>Head cannon accepted<<<Moriarty's been fangirling over Sherlock since they were children.
I don't usually go in for the "Imagine Your OTP" posts, but.this would be hilarious.
BBC Sherlock Holmes Jim Moriarty <<< *le me*
Sherlock taught me that running with Mycroft Holmes while holding a skull will lead to falling off a building.<<< Terrorizing/ Viciously killing with John Watson while holding Sherlock's scarf will lead to bombing a train.
