You guys don't realize how disrecptful Rei proposition is .
He basically want to replicate WW story and make Baam child his pet too .
That child would be strong but like all non irregular will be Rei slave .
He is basically asking for Baam to be his slave and for Baam to start making prime grade child to become his pet .
He is utterly foolish , asking something like that to another irregular is crazy to begin with and to finish if he ever succeed he will be beaten first by zahard .
I am sure as hell he wouldn't have the gut to say that , in front of Urek .
To be fair, the tower knows Baam as "the irregular who is weak and has nothing special like Urek Mazino" as Pudidy put it.
If Rei doesn't know that Baam is Arlen and V's son, it makes a lot of sense for him to do so. After all, he is far superior and apparently, not even Zahard knows everything about the prophecy.
I believe that only Eduan who everyone believes has a treaty with Headon, Gustang who has an agreement with Luslec (theory), Blossom who learned from Irure (through the Phosenkal family leader) and Tperie who has the eyes of god know who he is. irregular, slayer candidate really is the son of Arlen and V.
"Ah, but luslec named it as a declaration of war"
Rei doesn't even know the names of two princesses in his family, imagine a slayer candidate.
I think the same goes for other FH like Yurin who are far from family politics.
