Panel 1: As the hoverbus floats down the highway to town, one child says that it was a great day at the beach. When another kid says that he or she is hungry, other kids say "Yeah....I could eat" as well.
Panel 2: The conflict is about to come into play when one boy directs the others' attention to a road sign for an ice cream stand that offers up twenty-five flavours.
Panel 3: You could almost hear Jeff Tracy count down "5! 4! 3! 2! 1!" when Liz says that she cannot see the sign and asks where it is.
Panel 4: When Patrick scares the crap outta Liz by asking her if she lost her glasses or something and she realizes that she has, it's "Conflictball is GO!!!" all the way.
Summary: The reason Heavy Weapons Guy is about to ask "Do I smell soiled Lizzie diaper?" is that unlike everyone else in the world, Lizardbreath knows what's waiting for her when she gets home.
