Sibling Love

The feeling of obligation, loyalty, and affection, shared between persons who traditionally but not always share one or more parents, despite the terrible things they did to one another as children and sometimes to one another as adults.

Clara and Tony feel sibling love for Libby, even though, during childhood, Tony and Clara would use a television remote to convince Libby that she was invisible and mute.
