Is this Brandon (The Dude)?
Page 56 shows Danni shaking a drawn character. This is back in the time when blobs were used for background characters so the fact that it is a colored character is possibly important. And then, if you look at the file name for the incentive that day (http://navcomic.com/wp-content/uploads/2011/05/8-sidekick-thinking-pg-56.png), it says "sidekick" and is talking about the boy (since he is the one thinking). Could this be Brandon?
The clothing on Page 56 is similar to the clothing on Page 136. And the clothing in the incentive is different. I'm guessing the clothing in the incentive is the original color but Aneeka decided a different color scheme for Brandon and so fixed up Page 56.
