Hi, I'll get to the point. This character has been sent on a mission where he is to use a name which isn't his own, so obviously the people in this place won't know his real name. When he is to engage in any conversation with these who don't know his name do I write 'said -real name-' or 'said -fake name-'. I just don't want readers to become confused and think there are two characters. Thank you in advance.
