It does! though I would have expected more thinking about the fact he'd had to relocate! Somehow this totally went right past me at the time, lol, which is why I didn't put anything like that in the fic :) (And indeed I wouldn't have had that whole exchange about oboe vs. flute, as presumably he would have known it was flute unless there was some bureaucratic thing where no one mentioned it to him... which... of course could have been the case :) )

My headcanon, now that you have brought this up, is that he was taken aback by suddenly having to relocate, and with some trepidation as to being involved with crazy Hohenzollern royalty at all, but also zen excited and interested by the prospect, and particularly excited he got to play flute :)
