In the wee hours of the morning, today’s episode “The Pet”—written by Ben Joseph and Greg White—was leaked on 4chan /co/. Out of respect for the creators, I held off of posting this until the time of the premiere. If you think this policy is misguided, please let me know in the comments.
When Wander and Sylvia board an abandoned spaceship, they encounter a horrifying alien monster that is set on eating them. While Sylvia sees the wild beast as a threat, Wander takes a liking to the ferocious little monster and tries to train it to be his pet. —Disney Channel press release
As for the chronology of the leak, the file was created “2013-10-03 08:03:40” (no timezone given), Anonymous posted a link on /co/ at 08:12Z, which is the first public mention I could find of it, then ovarianeruption alerted us on Tumblr. (Someone also put it up on mega.co.nz.) The leaked file is only 78 MiB in size at VGA resolution, so it shows noticeable compression artifacts in addition to being cropped to 4:3.
