I haven't quite finished it yet, but yes, this is something that sort of
leapt off the page at me the first time Laurence calls Temeraire 'Dear'.
Which came quite early on (as I recall just when they were about to fly off
to England). Just because 'dear' is not something you would expect a male to
call another male. I had to actually read back to check that I hadn't
misunderstood Temeraires gender at some point.
I was rather amused by the section later on where Temeraire was asking
rather wistfully if it was possible for dragons to turn into humans for a
while, and Laurence asks him why, and Temeraire is like 'Oh, no reason!'
And contrast the warmth and intimacy of Laurence and Temeraire, with the
rather cold awkward distant relationship Laurence had with his sweetheart
back home, and the subtext is in danger of becoming text. :)
