Panel 1: We start things off with an exterior shot of the house. Liz points out that Mommy has returned and April says "SHRIEK!!!" because Lynn has not adapted the bande desinee protocol of using a red exclamation point to represent the happy incoherent noise children her age make.
Panel 2: When Liz tells her to wait for Elly to put donw her suitcase, April reminds us that Lynn wants to honor her UK relatives by babbling Mum-mum-mum.
Panel 3: She then yells MAMA and latches onto Elly's neck as if she's going to vanish if she turns her head.
Panel 4: Now that she's got a barnacle child clamped onto her again, Elly thought-bubbles that sometimes it's the smallest arms that give the biggest hugs.
Summary: Today, warmth. Tomorrow, Aaron gets slammed for being a couch potato.
