Papu, you chatterbox! You more than anyone know how opportunities work in this comic: you take one as soon you get it and ask questions later. Analyzing it simply leads to 2-panel situations like this one.
Papu’s scream is that special kind where the person to whom you’re explaining something JUST DOESN’T GET IT. It’s that special kind of “AAAAAAAAAAAAAAHH!” that feels oh-so magical once you’ve finished screaming.
