First of all, don't make it all about you. You said "all of us." But hey, we said we wanted to know the nature of her condition, and now we're being told! That said, we're not IN that cafeteria, where people are probably saying either "What the fuck's a cleft palate," or "So?" And if they fixed it when she was four, why does she still talk like this now?
Panel 2: Oh, okay. Well, since this is the Foobiverse, this will be seen as heartwarming, how she struggled and all. But, and I don't wish to be crass, I still don't get why she's had twelve years, or however many, to catch up and she still has an impediment. There must be a physical cause, but she just said they fixed it. Christ, there's inconsistency WITHIN strips.
Panel 3: Oh, here it comes.
Panel 4: Oh, GOD! I had a silent scream just now! And sure enough, people are having a moment of revelation. Is that Gerald? And if so, who's the girl? In real life, I'd probably be like, "Fuck you; I never made fun of you! Don't guilt-trip me!"
