Panel 1: This makes no sense and is poorly drawn.
Panels 2 through X: See description of Panel 1.
Hypothesis: Lynn should have retired long ago.
That being said, let's get to the real monstrosity.
Panel 1: We start off with April talking to Gerald. She asks how things her, he says OK, she asks if he's still speaking to her and he says "Sure". This, as we expected, is April apologizing for being a bitch Saturday. Too bad she doesn't apologize to us for her slovenly speech. You will note that dantheman's take on this is dead bang on.
Panel 2: She hangs a lampshade on this fact by rambling incoherently about how she, Eva and Duncan were talking. The consensus they derived and that we did not see was that no matter what happened, the four of them must remain friends.
Panel 3: He sees no problem with this and asks her if they can keep in touch. She enthusiastically agrees.
Panel 4: Her next chunk of verbiage is about how the four of them will keep in touch with Luis and even Becky. Perhaps, one day, far down the line when they're fat and old looking (judging by how unkind the years have been to everyone in Milborough, 2023 at the latest.), they can look back at 'simpler' times and glory days like this. "How awesome we were, standing in a hallway a year before we graduated!"
Panel 5: As an actual teacher walks past, they both point out being old is tough to imagine. You can imagine my surprise to see an adult in a position of authority present. Based on April's wretched grammar, I naturally assumed there were no teachers.
Hypothesis: Tomorrow, she sits in her room and thought-bubbles something stupid. That, or she says something stupid out loud and John/Elly thought-bubbles something that betrays his/her total lack of awareness of who April is.
I hope that next week Lynn stops tormenting us with dreadful filler material like this and gets back to the Settlepocalypse.
