The boss music there is actually an arrangement of The Decisive Collision, which admittedly is basically the Cold Steel equivalent of Silver Will anyway (it plays during some of the Crow fights in CS1/2).
Olivier not dying didn't bother me because of course he didn't, but I really wish -someone- had actually died on the Courageous - probably Victor since CS3 pointed out he was permanently nerfed following the McBurn fight anyway (and no one would've cared if Toval died tbqh). Relatedly, calling him "the greatest swordsman in the Empire" is blatant Aurelia disrespect and I don't stand for it
Yeah, I get those two songs mixed up because they sound kinda similar to me!
and yeah, nobody really cares about Toval except for his connection to Carnelia and the fact that he's Toby from those books. I think they've been selling Victor as the greatest swordsman since CS1 when he owned Ogre Rean. Plus, it would've been really jarring for Aurelia to defect because of the Curse, and it damages the credibility of Musse's cause if she's not there. So I get why they went with Victor there.
