Hill actually somewhat understood why Agleya thought he and Haiweirsen were alike. He didn't seem that distantly related to Haiweirsen. If it weren't for the inheritance from the Crystal Flower, he should have been much like Aurelio.
Normally, he didn't feel it, but when that father and son stood together, they were exactly the same.
Hill was also very much like Haiweirsen, not in appearance, but in aura. He also had a bit of Aurelio's aura.
They hit it off from the beginning and trusted each other for a reason.
With the growth of his strength, Hill also felt some of the uniqueness of his own soul.
Especially after living with the Earth Bear day and night, he understood that it wasn't just his body that awakened the Earth Bear bloodline, his soul also had some connection with these bears.
To be more precise, it should be related to their creator, the Goddess of the Earth.
