Panel 1: We're back at an oddly blank-looking Pattermanse because Lynn decided she no longer likes the delightfully cluttered backgrounds that we all used to associate with the strip. John asks Elly why she bought Mike a goldfish. Her answer: he wanted a dog and getting a fish is easier.
Panel 2: She goes on to say he has to learn to be responsible for a pet. Translation: when the thing dies in a week, she can get on her high horse and say he ain't ready for a pet. No wonder he's effed up with her pulling crap like that.
Panel 3: We then see another annoying hallmark of the last years: silhouettes. To be specific, those of John and Elly. She says that if Mike does well with the fish, she'll let him get a pet higher up the food chain.
Panel 4: Instead of asking why there's a fog bank in his house, Mike asks if that means they'll get him a pet that will eat Fred the Fish.
Summary: This isn't really the classic style as much as it is Lynn's take on it. This foul-up won't last long enough to be there when the children's book comes out. Elly is still made of fail. Farley is still dead.
ETA: The banner has reverted to congratulating Lynn on unleashing a concept that's doomed to failure on the world. I wonder when she'll finally have her own personal spinning-butterfly-naked-boy-army moment and hang up the brush for good.
