Panel 1: Well, I wanted a logical progression.
Panel 2: She allows as how maybe she gave him a hard time about his plans to blow off Uni to tour with Becky. That's an understatement, isn't it? It's his life to do with as he pleases and Perfect Pattersons have no say in the matter.
Panel 3: Duncan reminds her that Gerald could be doing the right thing (Translation: Get over yourself, pickyface!) while Eva sets up the punchline by reminding her he could always become a mature student. (Translation: So Brian May is a loser, Martian? Give your head a shake.)

Hypothesis 1: They should not show April at school as it brings out the self-righteous bitch in her. Also, she should find a better class of losers with which to associate because those who do not smack her down make Aypo come out and play.
