'Something amusing you, High Mage?' Dujek asked as the group approached.
'Welcome, High Fist,' Quick Ben said, straightening, adding a slightly deferential bow to Tayschrenn. 'Colleague...'
Tayschrenn's thin, almost hairless brows rose. 'A field promotion, wasn't it? Well, perhaps long overdue. Nonetheless, I do not believe the Empress has sanctioned that title yet.'
...then QB goes on to explain that he's already masqueraded as a High Mage.
Here's what I don't get.
1) It was Tayschrenn who, in MOI, said something like 'Where's Quick Ben? As of this moment he is a High Mage. That bastard can't hide anymore.' immediately following the assault on Coral.
2) His brows rise - a natural reaction implying that he is not saying this sarcastically or jokingly. If so, why has his opinion changed between books?
3) High Fish Dujek just called him a High Mage. Tayschrenn obviously thinks he should be too. Why would he ever snarkily question what he himself demanded, like, a few MONTHS ago. I'm not sure on the time lapse from the end of MOI to TB maybe a year, maybe less. But not THAT long. Basically both characters just travelled to 7C.
4) The Empress herself must adjudicate over making people High somethings? We saw Keneb become a 'fist' without her around. I'm sure more examples exist. This seems... anal. The Empress is, like, never around. How would anyone be High anything? If ANYONE could give a field promotion, wouldn't it be Dujek?
5) This seems like its in here to A) Have QB outsmart Tay again

Is this something more than I think it is?
Something less? Thanks!
PS: This is a great scene where we finally get to see Bridgeburners relax a bit and enjoy(?) each others' company.
