I think Marilyn was worried about getting Steve out to fulfill Herman/Lily's wishes ("No one is getting eaten tonight.") which are ultimately to protect Eddie. I don't know that she shows any concern for the scoutmaster for the scoutmaster's sake. Her admonishments to Grandpa are "This is not how we treat company." and "Aunt Lily has expressly forbidden eating anyone in the house."
Exactly so. The notion that she was complicit in deliberately killing Steve is preposterously unobservant.
