Freedom is the second child of Lucina and younger brother of Isaiah. He is the only child that was born in the caves and delivered by Doc. When Wanderer arrived at the caves, Lucina kept her children as far as possible from her, but when Wanderer was moved into Pet's body, Lucina's and her children's attitude changed towards her. Freedom in particular crawled in her lap in every opportunity, burrowing his face in her hair.
Freedom is at particular risk from the souls, as children are highly desirable as hosts, and are unlikely to remain after a soul is inserted. Even if the soul is removed, it is unlikely they will return. This was the case with Jodi (Although she wa san adult) and Pets host.
