PrePub - Ascendance of a Bookworm

To leak anything, he'd have to learn of it first, so the burden for the time being is on the archducal family. With Wilfried having risen out of his pit of despair, confusion and self-pity for now... I think he'd be well enough inclined not to give anything away willingly.

Even if they got the information, I don't see how it would benefit any of Wilfried's retainers to leak it, with one exception: Barthold. I'm still not sure whether he's just trying to ingratiate himself with Wilfried, to make his own life more comfortable and he ended up sabotaging Wilfried out of idiocy, or whether he's intentionally sabotaging Wilfried.

We know that Giebe Dahldolf for example is living freely, as if he had his own name, while his name is actually held by Veronica, so Wilfried being locked up in the Ivory Tower could be a rather attractive outlook for someone who only gave his name to him to escape punishment by association.

Alternatively, he could have hoped that should Wilfried be disinherited, he would be forced to give the names he got back. Not an entirely unrealistic theory, since they were meant to swear themselves to the archducal family, which in such an event Wilfried would no longer be a part of. Of course this carries the risk that Sylvester might insist that those who regained their names from Wilfried, pick a new archduke family member to swear themselves with, but with how much of a softie Sylvester is, and how the danger of the Veroncia faction is pretty much gone, there is definitely a non-zero chance he might just let Wilfried's ex-name-sworn keep their names.

If he wants to please Wilfried for better treatment, it would be in his own interest to keep quiet. But if he wants to sabotage Wilfried, he's sure to leak it, if he manages to glean the truth. To maximize the potential damage to Wilfried, he would need to rile up the Leisegangs, while they believe they still have a chance to keep Rozemyne in Ehrenfest, because those geezers very obviously have no clue how the nobility and royalty outside of their duchy actually works, as Rozemyne realized this very release.
