Italics are thoughts.God, he looks tired,YYY realized; for a split second, almost ghastly. XXX, you have much to answer for. But XXX knew that.
I am not clear as to why some parts are in italics and some are not. A bonus if you explain it to my satisfaction.
Anyway:
Book? The Vor Game
Who is YYY, who thinks the italics part? Miles
Who is XXX? Gregor
Who is "he" (not a trick question, "he" is neither XXX nor YYY) Aral
What XXX has to answer for... Gregor ran away on Komarr, causing all sorts of problems back home (not to mention the problems keeping track of him in Hegen Hub).
As far as the italics go, the best I can come up with is that Miles wasn't thinking that specifically. It turned from thoughts to narrative. Alternately, they didn't catch that it should be a thought the first time around (according to Lois, italics were a bit harder to indicate when she first started writing), and it just stayed through the reprints (it's like that in my copy of Young Miles, too).
