Octer and Lynol both stepped out of the room in which they were tested, upset over different reasons. They both finished rather quickly, since Octer's test was quite straightforward as well. After all, him being a shield bearer, the only thing that had to be tested was his ability to wield his shield. And since he could very easily move his tower shield around as if it was made of paper to block any incoming attack, it became clear to the testers that he was skilled enough to be a member of the martial alliance.
But even so, he wasn't particularly happy about how things went down after the fact, or even during it. After Lynol's fight with Liam, Octer was practically completely ignored, since everyone was shocked at the idea that Liam was damaged by a rookie.
