Monroe is the 23 year old son of the founder and head of H.H.H. He was sent away and lived in boarding school for 9 years in Yorkshire with his aunty, which is why he has a strong english accent. He is bitter, angry that the twins became field agents at record speed, and took his place as the youngest people to work for H.H.H. Because his mother is the head of the organization, he tries to avoid speaking to people in fear of abuse of power.  

His voice is very northern english, he likes to drag out certain sentences and only speaks clearly when arguing with Edgar.
