It's more of stupid Elly getting all pissy because he's free and she ain't.
Panel 1: As he sits on the couch bouncing Lizzie on his knees, Phil tells Elly that his jazz quartet is booked over the holidays for a high-paying gig at the same venue it usually is.
Panel 2: As she hands him his coffee, he says that he likes being at the Pattermanse that time of year as he gets to see friends and family and keep in touch.
Panel 3: He then reminds her that he rented a car and will be in and out; she confirms that she knows the routine.
Panel 4: She then asks a question that ensures that she'll set Connie up to be humiliated and add fuel to her idiotic and petty vendetta against him: "Will you ever settle down?" He reminds her that he's sitting on her couch bouncing his niece on his knee.
Panel 5: She reminds him that she resents his happy, care-free existence by saying "I meant for more than a week."
Summary: The nifty thing about the catalog is that it allows you to see that Elly has always bitterly and vocally resented that Phil has things easier than she does and will not let go of the past; this means that she will lie like a son-of-a-bitch and get Connie's hopes up for nothing in order to drag Phil crashing down to the same life of misery she has out of pea-brained malice.
