Marlo was surprised that anyone would bring up the children.
There is something to be said for letting things out in the moment you feel them and then moving on from it right away. The Smalls had clearly been holding a lot inside. Though there were moments when they seemed to stand apart, in their attacks on NeNe they aligned from the start.
I have to say, I was shocked that anyone would try to use children as a line of attack. Isn't that bad etiquette to try to embarrass someone's child? Though NeNe read her nicely, it should still never have come to that. Seems dangerous ground to tread when your own children are still young. Who knows what the future might hold for them?
