An episode will focus on James angsting about growing up... specifically about wearing clothes full time.
His parents are clothed, so this is probably a normal part of growing up for marshmallow/bubble people.- Probably jossed, in the graphic novel, it states that his parents have told him a bunch to do so. But, James still probably feels insecure wearing them. I think the reason his parents are clothed is because if they weren't it would lead to some.. interesting fanart.
James' parents were originally going to have another child, but miscarried it.
In Behind The Frenemy Lines, his dad said that they've wanted to have a do-over when his mom says that it would be okay with her for Echo to move in. This implies that they were originally going to have another child (Most likely after James was born)- Another possible theory, is that it was implying that season 2 could have had an episode about James' new baby sibling. But due to season 2 being such a short season, and Toasty's Goodbye being the season finale, they just couldn't include such a storyline. So they probably either just scrapped the plot, or just forgot about it
Byron Sellers is a pedophile
Why else would he be stalking and harassing someone who is clearly a child? Also, out of both the times he visited James so far (Almost Home Alone and the graphic novel), James' parents weren't home...
