*sigh
I have a feeling that Marika's mother needed a hug right in the middle of her breakdown.
Waiting past that, with her mind now dead-set on destruction (to herself, to that guy, and anyone else that might be "in her way"), even these sincere gestures will fall flat.
...well, maybe I'm just projecting. I think hugs are powerful. Plus, omelettes are peak.
In any case, it doesn't matter if it were just Marika-chan or Marika with Takae's memories. No good mother shouts at her child, right when said child is genuinely attempting to console her own parent.
