Original Commentary

So, why are the cages in the back always empty? Because Isabel doesn't like drawing a whole bunch of animals in the backgrounds each time. It'd be odd if they were drawn into the backgrounds permanently, because the vet's kennels would be full of animals that never moved. And if we saw the same room four months later, it'd have the exact same animals in it. You'd have to wonder where the owners were and why they hadn't picked them up, you know, ever - Terrence

Modern Commentary
I like how Isabel approached this moment. Something might happen between Sofia and Patrick. But we don't see that. We see Sofia talking about what might happen to her friends.

It's less hesitant this way - Terrence
