Ever heard that two's company, but three's a crowd? Cius is in precisely this generally unenviable position. Sure, in a case of reverse Stockholm Syndrome, the prisoner managed to convince at least two of her guards that she was pretty cool, but Lucretia convinced Lelei... considerably more than Cius. It may have been a bit awkward for our poor guard at Agate Prison.
Still. There are solutions. For instance, working out any lingering issues in the battling arena! Cius isn't much for damage, preferring his sword over the Suikoden world's more dangerous runes. But he certainly knows how to take a hit, perhaps learned from dealing with the more unruly prisoners. Cius'll soon prove his worth to the DL.
