Lots of discussion on this one, as I guess any comic involving parental friction might've had. This is a memory Eve is revisiting, one she might not have remembered or remembered differently. How relevant is it to the story? It shows Eve's propensity to wander and indulge her curiosity, and her mother's urgency to suppress this and impose fear. There is a dual avoidance and attraction to pain - even as her mother strives for safety and order, she has the reckless impulse to drown. Eve recognizes that her mother isn't fully making sense, and this complicates her sense of attachment, so that she can only conclude her mother must hate her. She will (much) later realize the pain her mother felt, and how similar the two of them are. In the final panels Eve is meant to be thinking, not saying this to her mother. It's this thought that now hits her the hardest.
I don't know how cogent an explanation this is; truthfully a lot of it just felt right in my guts, and I think about it a little differently every time I read it.
