Sharp-witted, ruthless, cold, manipulative, and deceiving woman. But in her Mama persona, Isabella is capable in putting on a motherly, selfless, and kind-hearted facade whenever she is around the orphans in Grace Field House, and hence was able to earn the trust and love from her foster children. Very mercurial, capable of switching between seemingly true affection for the orphans to extreme loathing and threat of violence towards those who defy her.
