Original Commentary
We've been talking about adding old Dr. Marvello into this arc since the very beginning, before any part of the script was written. We knew what part in all this he would play, but we didn't quite know where. We had originally planned on having Dr.M show up in this comic, but decided against it. -Isabel

Modern Commentary
The most surprising thing about all this is that Dr. Marvello actually has a real doctorate.

Also, Kimberly wasn't a performer. Why was he photographing her? Apart from because he's kind of a creep - Terrence

Original Commentary
Isabel made a few changes to this when she was lettering it - for a start, she changed it to a photo album. I had the photos in a box. Why? Because I forgot people put photos in albums and I was going to have Kimberly flipping through them like records - Terrence

Modern Commentary
Dr. Marvello is named after a Klaatu song. The song is about a mystical sex/relationship therapist.

The character is some guy in a culturally-inappropriate turban who keeps shouting about how he has learned the secrets of oriental magic. That kind of thing was common back in the actual vaudeville days but there's a lot of stuff that has fortunately been left in the past. His act is mostly juggling.

He didn't cut Brisbane on purpose but he didn't go out of his way to include him. In his defense, Brisbane was an untalented rando who showed up towards the end and took a few months off- Terrence
