I wish I were right; that's because what really faces us is Lynn's disturbing take on the father-daughter bond.
Panel 1: We start today's strip with a close-up on Lizzie, who's wearing those overalls with the ruffled shoulders that agitate most of us. Lynn further antagonizes us all by the means by which Lizzie shows her appreciation for the cookies she's eating. That's because Lizzie talks Hulkspeak and says "Uh! Cookie! Num-num! Cookie GOOD! Nizzie eat cookie!"
Panel 2: We zoom out to show a smiling John and Elly; John uses Lynnglish to indicate how he feels about his daughter and says "She's growing up, Elly. She's walking and talking and turning into a real little girl."
Panel 3: Lynn indicates her displeasure that Rod and Katie were forming an emotional bond she wasn't part of by twisting his harmless comment "I just hope I have a few years before she she finds another boyfriend." into something unhealthy; she accomplishes this by making John's smile look positively predatory.
Summary: As everyone is about to say, he need not worry; in twnety-five years or so, she'll marry a man so like him, the realtionship will be incest-by-proxy.
