Panel 1: We see an exterior shot of the house that makes it look as if it is telling Elly that they've got two months to figure things out instead of Phil doing so.
Panel 2: Phil and Elly set up the July arc when they agree to put off squabbling over things that their parents will sell anyway.
Panel 3: When Elly says that seeing their old house empty (or lived in by other people) will seem strange, Phil wonders what they're going to be calling home going forward. As they say this, it looks for all the world as if Liz just choked on the food she's got shoved in her cheeks like a damned hamster.
Panel 4: Liz reacts to the 'confusing' thing they said by thought-bubbling something stupid about how 'home' is the Pattermanse. This is because she is a fragment of Lynn's personality and doesn't realize that 'home' is where you happen to find yourself and not simply the place you grew up.
Summary: No, Liz, Casa Foob is not your hoooooooooooooooooooome. Your hooooooooooooome has a little gated community in the basement for you and the Weird Frenchy Girl and James Allen. The Pattermanse is Mike's home because he can make more kids named Patterson. Ah, well. This segues into the last story arc in which Phil is a protagonist instead of a supporting character.
