Ves made the right choice by gathering all of the expert pilots together. If he spoke to them on an individual basis, then it would be difficult for him to fend off their remarks.
Now, the expert pilots pretty much argued amongst themselves. Ves, Calabast and Major Verle turned into inanimate props as the expert pilots each expressed what they thought about the current campaign.
Just as Ves expected, Venerable Jannzi found the most fault with his decisions. To her, trading lives for training and plunder was a horrible deal.
It didn't matter whether the Larkinson Clan gained 5 expert pilots and 9 expert candidates in total. Each breakthrough came at the cost of at least several dozens of lives!
To Jannzi, this was no different from cutting off the necks of innocent Larkinsons in order to fuel a demonic ritual that directly enabled her to break through. It was a reprehensible trade that should have never taken place!
