Ethan is aware of hidden bloodline that resides inside Alice.
This bloodline is not something trivial that a higher being grants to lesser being, but it is tied to her origin.
What does this mean? It's very simple she can completely transform to said bloodline type and not only have ability to reach at the peak of bloodline to suppress the highest beings of the same origin.
The bloodline that Alice inherited belongs to her mother who is currently alive and one of the strongest being in Primal Verse.
Ethan is already aware of her identity but hasn't her encountered during his 15-years life in Eternal Realm. But he has read about her from the Books and memories crystal in his homeland.
During first meeting with Alice, he scanned her and recognized the identity of her bloodline but thought that it was noting trivial but later when his power increased, he sensed that her bloodline is not simple.
