Sam, Giyon and Grivon spent three days dealing with the mercenary group. But now they got some leads that are even more confusing.
One of them is a young man whose identity that even the mercenary group doesn't know about. The other mercenary group is targeted by a woman and she turned out to be a woman that belonged to another small organization, but she was also found dead by the time they went searching for her.
As for the third organization, it is a mercenary group that did this by themselves. They are trying to suck up to Mari Clan as they originally operated within the area controlled by the clan.
Now they pissed someone off there too bad that they had to run away. They came to the Gaja Clan's territory, learned about Sam and wanted to sell some information off back to Sivan so that they could have their place secured back in their old territory.
So, this eliminated one of the possibilities.
