Panel 1: We start things off with a scene that would take place if Elly were in the next room because we have Liz as April's primary caregiver; as she points to Liz's mouth, nose and glasses, she wants to know what 'dis' is and is told what 'dis' are.
Panel 2: She keeps on playing 'Dis?" when she points to Farley, the window and the chair.
Penel 3: Liz says that they had a lot of fun but they've named everything in the house so should do something else.
Panel 4: We herald in a future where Liz sits in the back of a lima howling STOP!!!!!!!!! because simple wordplay is "obviously" an attempt to destroy her when April asks "Dat?" and Liz is baffled.
Summary: If you were paying attention, you'll notice that the baffled look on Liz's stupid face means that she's forgotten that she was a toddler already.
