Sherlock - I believe his version of an English accent is what is considered "upper class", or Received Pronunciation. It's the

stereotypical British, BBC accent.

Phoenix My headcanon is that he's got the mid-western, American 'non-accent', but he can get a little lazy on his consonants.

Nathan Has a Dublin/Irish accent crossbred with some Brit, I believe. He's definitely a bit of a mutt. He annunciates a little more than

what I've come to expect of a typical Irish accent?

enunciates? :|a

Both terms would be correct, honestly xD I mean enunciate, though.

Nathan announces things more than typical Irish people? X3

Probably! He announces things more than most people should!
