As I sent my clone through Belia's portal...it turned out to not be a trap. The sight I saw through my clone's eye before walking through wasn't an illusion or anything, it was definitely happening...a blonde guy with a sword, which was raised up and glowing, was fighting Persia and Fuo, it looked like he had taken some damage, but it was also clear that the two of them were on the defensive.
Wonder if he was also summoned from another world like those twins I fought...well, it really doesn't matter to me whether he's pure evil or has a heart of gold, or whether he's being manipulated or not, all that matters is that he's on the side of my enemies, which makes him my enemy as well.
