Karaoke is a charming old Earth pastime in which music which normally has lyrics is played without them and supplying vocals is left as an exercise to the participant. Ivan was coaxed into going by a local handing out drink vouchers for the bar which offers the activity, and there he got slightly tipsy, sang the only three Barrayaran songs in the entire catalogue, made out with a somewhat drunker girl, got her number, and stumbled home while some Earthling was stumbling through interminable verses of some song. It has not been a bad evening.
That's... not Miles. Miles natively has a Barrayaran accent much like Ivan's, except when he comes over all hills-like, and he can do a good Betan much like his mother's, but he does not have any settings that sound like a Londoner.
"A vengeful Komarran expat ran off a couple clones of Miles, would've been when he was about six, raised us for a substitution plot, whichever one turned out better was supposed to impersonate him and kill a bunch of people, the man hasn't picked yet but it's getting down to the wire, I need you to help me rescue the other clone."
"There's the boss and three loyal minions, all with stunners, and enough nerve disruptors to go around but they don't all carry those when they aren't expecting trouble. No other prisoners besides me and Mark. You might know better than I do how many people you need to deal with that."
"...I'm not sure how else to summarize it. She's probably... got some businesslike attitude towards finding two unplanned clones of her child have been raised by a villain backed up by lots of cultural history, a pithy saying, and a very down-to-earth handbook entitled So Your Child Was Cloned Twice Without Your Knowledge?"
"True. Still, there's no call for me to make you think about it. You clearly don't think it's funny. Maybe I should be joking with your Captain Galeni instead. He had to live through Ser Galen's idea of actual parenting, God help him. What must that have been like?"
