As for the comic, that’s nice that the characters themselves are sharing recipes, and that Dean loves Charlotte’s family’s cooking (carrying over from the Thanksgiving leftovers strip).
The cheese sauce recipe is very close to one I learned from my mom, except the recipe I do is four tbsp butter, four tbsp flour (all purpose), two cups of milk, followed by the cheese (an eight oz. block of cheddar I grate myself) and dashes of seasonings (paprika and cayenne). Typically it’s used here as part of a meal, to put over chicken, potatoes, and broccoli. The mac & cheese casserole my mom does increases the amount of cheese sauce, adds a little more milk to the casserole so that it doesn’t dry out, and uses grated parmesan and panko bread crumbs on top too.
It’s about the kids facing consequences for sneaking out at night, even if it was for a good cause, and the kids accepting those consequences (Heart did in a previous Sunday strip).
Hey! Someone brought up buses yesterday in the comments. Great minds thinking alike.
