The newest episode of the fourth season of "Steven Universe" will be called the "Onion Gang," where the viewers will be able to meet Onion's friends. Onion, a minor character who debuted in the "Laser Light Cannon" episode, is reportedly keeping some gem mutants within the confines of his basement.

According to Game N Guide, there are rumors that the monsters from the "Nightmare Hospital" from way back in the show's second season could have originated from Onion's friends. As seen in the previous episode, this child of Yellowtail and Vidalia has a meek personality, and he barely talks to anyone except his parents. He has an aptitude to help, but at times it becomes nothing more than just blind obedience.

The last episode of "Steven Universe" was supposed to be entitled as "Gem Harvest," but it seems that the showrunners were trying to debunk some spoiler news by changing its title to "Last One Out of Beach City." In this episode, Amethyst went to her first concert along with Steven and Pearl. Greg was supposed to join them, but at the last minute he remembers that he had prior appointments with Barb and Vidalia. As such, he came over and they played cards.

Of course, while Greg feels sorry to have missed out on the fun with Amethyst, he is unable to decline Barb's invitation due to the fact that the latter will never take no for an answer. Actually, she even went so far as to threaten him, saying that she will hold his mail if he bails out on her. As such, the scenario was concluded with a sad Amethyst.

Regardless, the seventh episode of the fourth season of the hit show "Steven Universe" is set to air on Sept. 15 at Cartoon Network, unless the channel decides to reshuffle its schedule once again.
