what did melissa mean by this?

i don’t remember which episode specifically, but it was in season 6 when the minis did the monster dance and the three girls were there. when the moms were confronting the new mom, jeannie, about leaving and not finishing what she started and jeannie brings up chloe, melissa says “don’t go there because you don’t know the whole story.”

was melissa saying that in defense of chloe, or in defense/support of abby?
