Panel 1: We start with MikeClone asking RetJohn if they can make paper snowflakes to pass the time.
Panel 2: We next see them at the kitchen table as RetJohn hands MikeClone some parer and scissors.
Panel 3: As the two of them do so, we see NeoLizic put one of the pieces of paper in her mouth.
Panel 4: She cries out because MikeClone won't hand her the scissors so she can poke her eye out or cut herself or something.
Panel 5: They all shout out with glee as they make more snowflakes.
Panel 6: They then tape them onto the picture window.
Panel 7: We next see RevElly on the porch with bags in hand. MikeClone tells her they've been making snowflakes.
Panel 8: She's stricken with horror and rage because they left a mess behind for poor, pitiful, downtrodden, ill-used her to clean up.
Summary: Like I said, I'd feel sorrier for her if I didn't already know that she would have yelled at John and the kids for tidying up the wrong way. They might have done so in a means that was efficient and effective and be unfair because it highlights how sucky she is.
