Bia's Links
Kratos is the easiest of her siblings to open up to. She "melts" when she is with him. She doesn't want Kratos feeling guilty for her own issues and can tell his feelings despite the fact he tries to hide them. She wants to please Kratos and show him he's a good enough baby brother.
Protective, despite Bia being older. He doesn't like anyone messing with his shy older sister. They used to butt heads a lot as children, but they don't any more. Kratos feels guilty for all of the times that he teased her, feeling that her personality is his fault.
