(Original Publication Date, 22 September 1990)
Panel 1: That night, we find John and Elly in bed going over the day's events. As near as he can determine things, the kids have accepted the fact that some time in March, they're going to have a new sibling. Given that Mike's "acceptance" is contingent of his not having to change diapers or babysit or anything and that Liz has just realized that her new job description is primary caregiver, one would accuse John of being what he turns out to be: a moron who doesn't know what's going on under his own roof.
Panel 2: He, on the other hand, has accepted it. He might have to build Mike a room downstairs or find a larger house to live in but he's accepted that.
Panel 3: He turns to her, says that he realizes that she's upset because it's a rude shock but hopes she'll some day grow to accept it too. She hints at never accepting it by saying that there is one sure thing about all of this.
Panel 4: When Elly whines that she'll certainly grow, he is astonished. I am not. I know that Elly will resent him and April forever for taking a non-possibility away from her.
Summary: It seems that John is a bit premature about all of this acceptance that isn't actually a thing. That's because we spend next week watching Liz think that she's about to be cast aside for the new baby. This leads to John the idiot we've come to expect when his response to Liz asking a question anyone with a brain could foresee is to go all goggle-eyed in horrified confusion and ask himself "What is it with this kid?"
