Who says they're not already a couple... I want it to happen but I doubt it. It's a little kids show and therefore it is very unlikely that we will ever see a couple of main characters. Because little kids think that stuff is well...
Well, since they don't act as a couple in the anime, it's the same as not being a couple, unless they announce they had been together for years at some point. They're not real people, so they can't do other stuff while we're not looking haha. So in my opinion, the anime would need to demonstrate it to make it true, thus they're not a couple.
I find it funny the producers don't include a bit of romance in their show because it's intended for kids. I remember being about 9 and hoping so much they'd end up together :P. Princesses do in Disney movies, kids won't be traumatized.
Goodness no. James is so not interested. Neither is Jessie, not really.
Well, they need each other so much it's a bit intense for a friendship. Still, they don't show any kind of real interest, I agree. Honestly, I believe the producers just don't know what to do with these two and messed them up by making them act in a way that fit best with the story of each episode, haha.
By the way, have you seen that oh-so scary picture? I hate it, it's so not them :(.

I think this manga is considered official material, but it's not directly related to the anime for sure. However, the anime might inspire itself from this, who knows?
