Panel 2: I may be reading too much into this, but perhaps Gerald's not cool with the idea of April inviting someone, or doing anything remotely like making a decision. Perhaps he's another reason Becky quit: because she was tired of him trying to be a dictator and undermining her perfectly good ideas and contributions.
Anyway, what does Duncan mean, "apparently"? I thought he knew Eva too. Doesn't he have music class with her or something?
Panel 3: Yep. Gerald just has to have veto power. He also has a wattle. What IS it with these rapidly-aging Milborough men?!
Panel 4: Still with the white hair? Or is it a colorist's mistake?
Panel 5: Okay, so another hottie for the lead singer. And Duncan is smitten. Sigh.
