For Whom the Bell Tolls in New Teaser for "Yellowstone" Season 4 The brief clip, which lasts only a few seconds, hints that death is coming to the ranch. The Season 3 finale ended with several Dutton lives in limbo. [This was disappointing news for fans who were eager to learn the fate of John Dutton (Kevin Costner), son Casey (Luke Grimes), and daughter Beth (Kelly Reilly). The first trailer for "Yellowstone" Season 4 did not reveal much. This new teaser doesn't say much more about what to expect, but it certainly sets the mood.

A black raven appears in the video, flies away, and settles on the "Y" logo of Yellowstone Dutton Ranch. Ominous bells ring and crows caw." With the words "Revenge is worth the wait.

The raven has been a symbol of death in many cultures and belief systems. (Native Americans, however, consider it a good omen because of its intelligence.)

The raven is also a symbol of death.

The use of the raven in combination with the sound of bells seems to be a major hint that a major death will occur in season 4 of Yellowstone. In the season 3 finale, a bomb exploded in Beth's office and another shooting targeted John and Casey. The video's tagline about revenge indicates that someone - possibly Rip Wheeler (Cole Hauser) - is going to get payback for the attack on the Dutton family.

It could also be a cheeky reference to the long wait that fans have already endured to see Season 4, as Yellowstone Season 4 will likely air in October or November. In the meantime, one can watch Yellowstone seasons 1-3 again.
