Maria is the youngest. By a larger margin (Kain and Ivan are roughly same age but upper 20s-lower 30s. Issac being...just over 1,000 years) and is still in an age where she could get guided properly. She's basically in a redeemable state and seeing Olivia's kindness and getting to spend time with her enemies in a friendly way helped out.
