Davis naturally knew why, as Soaren was separated from his family. As a forthcoming and straightforward Golden Crow, he was a passionate man and cared about his people a lot. To be separated from his family with their fates unknown has got to hurt.
However, Davis knew Soaren hadn't said anything or left to avoid causing trouble for him. After all, if Soaren left, then Fenren would also leave in search of his family and thereafter could be caught and implicate Davis once again. They could see it happening and remained silent, not troubling him.
However, that just made Davis feel guilty.
That was also why he wanted to bring them here to talk. Another reason was that he was finished with his evolution technique and wanted them to rise in bloodline rank.
If he could change their bloodline, then they would not be easily recognized. That would allow them to travel on their own if they so decide to.
