Once she knows a heartbreaking news about Renny's condition from Natasha, she genuinely determined to protect the child at all costs, even though he isn't her biological son.
And yet, she did, she protected him from a fatal traffic crash.. You'd never imagine a mother's concern and love. So Vol 3 is basically all about family After her death (she's already "dead" since the start actually, it just that she's disguising herself to be one of the humans, she tried to prove her mother of how being a living being aren't just about being 'fragile', 'weak' and 'pathetic' — some people ending up scarificing themselves even though they'll do it out of pure panic fear, not bravery.)
she thanked Natasha as she promise she will take care of Renny afterwards — after Cornaty gets back to her 'rest'.
