Does it have any supporters here?
Well, I was a bit surprised there isn't a thread here discussing it. Though it's a fanon by now due to the lack of hints, and even anti-shippingness, Jessie and James are main characters, beloved for some, and the rocketshipping fanbase is still big. Anime =/= manga, but it's interesting to note that it's canon in the japanese comics.
To bring up a topic, I've seen some people claiming rocketshipping is dead in anime. I didn't get to see the anti-hints yet, but were them blatant enough? According to Manene ep, James sucks the idea of him and Jessie being a couple... as a rocketshipper, I would feel sorry, but that fantasy scene of James wondering about being Jessie's "housewife" made me laugh insanely! The Bicker the Better is also considered an anti-shipper ep... but it was also funny as hell. Maybe the comedy is what makes it so nice.
Isn't it cute when they hug eachother?!
