In Season 4, Jacki Weaver will portray the character Caroline Warner, who is the CEO of Market Equities, the company that has been aiming to take John Dutton’s land and is clearly no longer altogether reasonable.
This is the very same Market Equities that Josh Halloway’s Roarke works for, so I’d imagine John Dutton will have quite a few things to say if he and Caroline ever come face to face.
Weaver is taking on a recurring role with Caroline, which means we might not see her in every episode, but you can bet her character’s presence will be felt as the vice grip squeezes on the Duttons to sell their land.
