The answer is none of the above. She's backpedalling!!
Panel 1: We join the Pattersons a few hours after yesterday's mess. Elly is telling John that maybe it would be all right if Mike had something to eat after all.
Panel 2: John tells her something obvious: if she sent him to bed without dinner, she has to not give him dinner. (Notice he doesn't question not giving him dinner.)
Panel 3: If she caves now, he says, he'll learn he can walk all over her. Besides, he can go one night without eating. (Notice he doesn't realize that this will make Mike think that his parents don't give a rat's ass about him. This is because John is a jackass animated by the need to push his children around.)
Panel 4: All that tainted common sense appears to have sailed right over her head because she whines that she couldn't live with herself if he did.
Prediction: She'll slip him a little food tomorrow thereby ensuring that she has no credibility. This meshes with her idiocy in denying him food in the first place.
ETA: Now we're back to the ugly-ass banner that says "Congratulations, Graduates." The ugly-ass banner that celebrates the July holidays appears tomorrow.
