Panel 2: Jeez, a flashback! Elly looks like a specter is emerging from under the sink. And I guess this is another example of "help just happens". OR, maybe this was Viv's way of saying that Liz is a slob.
Panel 3: Is that a leaf falling, or is something draped over the edge of the roof? And there's Jesse again. Did he leave the yard at all over the summer? Or worse: was he sneaking in through the window and sniffing Liz's sheets? And I wonder what that ellipsis is leading to... ETA: I just noticed something else. "Reminded us that we were living close to nature". Elly, what's this "we" stuff? You were VISITING Mtwiki.
Panel 4: Ah yes: another "rural life is dirty and smelly" gag. I'm going to have to wait for the large-size version to go up before I can be sure what Elly's doing; presumably she's covering her mouth.
