I usually download any old episodes that I want to watch, but when I can't be bothered to access the computer, I use my Digital Cable "On Demand" option, which usually has random Disney XD shows loaded, and always has at least a couple Gravity Falls episodes on there.
Not knowing the episodes by their numbers, I had to check the description of one such loaded episode the other day, and I was presented with something odd:
"Carpet Diem": Mabel finds a way to swap minds with Dipper and the townsfolk, so she uses her newfound ability to make a difference in people's lives. Meanwhile, Dipper swaps minds with Mabel and becomes Wendy's confidant.
After seeing that, I checked out some others and saw:
"Boyz Crazy": Mabel joins a secret knitting club and is pressured by her new friends to gossip, but when she tells them that Dipper likes Wendy, she inadvertently puts Dipper's life in danger.
The first description is odd, but still kind of close to the actual plot. But the second one is way off base. Is it possible that this is a description for a scrapped episode, or one postponed until the 2nd season?
