I would imagine these are children leaving their mother on whose body they've been living, and striking out on their own. (Or something like mosquitoes and human bot flies; careful looking it up, it's disturbing). If the mother dies afterwards, having sacrificed herself to give her children life, Surma might apply that to her own situation.

Of course the main thing is, she didn't emit a scream of cosmic horror and incinerate bug and clipboard immediately. She's apparently being desensitized out of her dislike.
