During the episode, GRAY revealed his recording studio where he spends most of his time. He also showed how he proceeds to make his music along and said, "I think it might be a little different for every musician but for me, nothing is set in stone or determined. Sometimes I make the melody lines first and at other times I make the beats first, it varies a lot."

While working, he met up with rapper LOCO as well to create something together. In the process, the two decided to call Sleepy to collaborate as well in which the rapper picked up brightly and asked GRAY, "Do you happen to have any beats you're throwing away?" to show how much he wished to work with GRAY. Upon hearing this, the cast of the show cracked up.
