Panel 2: Well, at least it's the guest bedroom. And I suppose only a really heartless witch would bar her doors against a child in need. But Liz is not in need -- she's just a wimp! And check the Smug, Closed-Eye Patterson Look on Elly. That's the same way she looked when she was Super!Grandma after Robin was born, telling Mike and Dee "I'm going to set up on your couch for the next three days." Can you imagine how Mira Sobinski would be excoriated if she did either of these things?
Panel 3: Yeah, I figured this was part of Elly's agenda. I mean, jeez, if they moved to the Tiny Train House, Liz would be forced to be independent! (I count marrying/moving in with Granthony as independent; at least it wouldn't be crawling back into the womb, like she's doing now.) And Elly, while you're poking John's belly, you really should not be emphasizing your own.
Panel 4: I feel your pain buddy; I really do.
