(Strip Number 4290, Original Publication Date, 2 February 1983)
Panel 1: As the Pattersons eat their evening meal, Mike asks if Daddy has gone. Elly says that he has.
Panel 2: She then tells them that since he took an early plane, they'll be eating supper without him.
Panel 3: Her next comment about how it's not the same without Daddy around and how they're going to miss him is a clear attempt to solicit some sort of treacly, sentimental comment about how much John means to Michael. Mike's response is a neutral-sounding "Uh-huh."
Panel 4: He then asks if he can have John's share of dessert; this unsentimental comment astonishes Elly.
Summary: While not really having an idea as to what the Lynnsight might be, it would seem to me that what we're looking at is Lynn getting back at Aaron for not being especially choked up when either she or Rod had to absent themselves. In her mind, he was supposed to be incapacitated with grief because she was not around instead of being like a normal child and simply accepting the world as he knew it.
