Original Commentary
I'm glad Isabel included the back of Caleb's head - I felt bad about him just showing up for a quick hi/bye appearance. But there wasn't really anything else I had to do with him. I considered having Caleb's manager show up and talk to Brisbane and Kimberly, but I don't have any plans for her just right now - Terrence

Modern Commentary
Caleb is fortunate that he has a manager; he's mostly unable to navigate the real world by himself. If he had to call around to book gigs and figure out transit schedules and such, he'd have to grow up.

Since he has a manager, he can spend all his time just Being Caleb, unfortunately for everybody around him - Terrence
