'Steven Universe' season 4 spoilers: 'Three Gems and A Baby' not airing until next month

After a long wait, "Steven Universe" season 4 finally returns tomorrow, Nov. 17 with "Gem Harvest," but fans will be in for another waiting game.

"Three Gems and A Baby," the installment that will follow "Gem Harvest," will not air until next month—Thursday, Dec. 1 to be exact.

This means that fans will have to wait for a couple of weeks to be able to watch the second episode of "Steven Universe" season 4 after its one month and a half hiatus.

The synopsis of "Three Gems and A Baby" suggests that it will be a flashback-inspired episode, just like how it was predicted. The description reads: "Greg tells Steven about their first winter together."

It teases that the "Steven Universe" season 4 will feature a first between the father and son. As speculated in the past, it will feature Steven as a toddler and Greg's preparation for parenthood.

"Steven Universe" creator Rebecca Sugar teased the new song to be featured in the next episode at the New York Comic-Con (NYCC) a few months back.

The song is called "I Could Never Be Ready" and it appears that it is a duet with Greg as the first singer. There is no word who will be singing with him although Sugar sang the song with Greg voice actor Tom Scharpling at the NYCC.

Some of the lyrics say "I could never be ready for this," which had many thinking that Greg is referring to being a father to Steven.

With regards to "Gem Harvest," the "Steven Universe" season 4 episode will be a 30-minute special. It will feature Peridot and Lapis trying agriculture. The synopsis for the episode reads: "When Steven has his autumn visit to the barn, he brings a new stranger into his life."

"Steven Universe" season 4 episode 8, "Gem Harvest," airs Thursday, Nov. 11 at 7:30 p.m. ET on Cartoon Network.
