Actually, we're at the beginning of the parent-teacher conference arc.
Panel 1: We find ourselves watching Elly talking on the phone in the kitchen; she's asking Brenda if she can sit for them tomorrow night.
Panel 2: As John's silhouette looks on, she says that she knows it's a school night but they'll be home early; Brenda must have agreed to do it because Elly says "Really? That's great!"
Panel 3: As Elly hangs up the phone, John says "She can come? That's good! Considering that Mike's a handful, I'm surprised she's so reliable." Elly replies by telling him that she gave her extra.
Panel 4: Her calling it 'danger pay' causes John to frown in sympathy for young Brenda.
Summary: It would seem that Lynn plans on padding things with a series of new-ruins that remind us that Mike is a non-linear thinker; this means that the Kool-Aid squadron will refuse to see that he's simply a destructive nitwit who craves attention.
