OK, I usually use italics for flashbacks but I don't think the book I'm currently working on will have any. But, what is does have is a nightclub, with security people, who all wear hidden earpieces/mics. The owner of the club also wears one when he's "on duty" so to speak, and although he might not speak much (unless there's a major problem), he will listen in on his security staff as they deal with the usual occurrences of an evening. In the bit I'm working on, the owner has just put in his earpiece and is watching everyone enjoy their night in his club when he hears a conversation on his earpiece concerning his security manager as he refuses entry to a drunk guy. So the owner hears the voice of his security guy who IS also wearing the same kind of earpiece, but he also hears the voice of the drunk guy too, even though he's NOT wearing one. My question is, do I use italics for the conversation between the security guy and the drunk guy, bearing in mind that the club owner can hear this conversation but is not in a position to see the security guy or the drunk guy ?? I'm not worried about this from the technology point of view - although it won't be in the book, the actual story is set around 20 years into the future, so the earpieces are totally wireless and have built in mics which eliminates the need for wired mics, although I appreciate that they would still have to go via the bluetooth on either a radio or mobile phone in the wearers' pocket. (I've only just started researching this tech, so I'm aware I could be totally wrong on the tech side of things.) Thanks in advance.
