Why does Ainsley hate Cooper in Landman?
Two seasons into Landman, the nastiest feud isn't Tommy versus the cartel or M-Tex versus the lawyers — it's the one at the family dinner table. Ainsley (Michelle Randolph) and Cooper Norris (Jacob Lofland) trade venom every time they share a room, and in season 1 Ainsley had to be forced just to hold her brother's hand during grace.
So what's behind it? Here's the honest answer.
The short answer
The show has never said. Two seasons and 20 episodes in, Taylor Sheridan has not written a single scene explaining why the Norris siblings despise each other. There's no buried betrayal, no revealed incident — at least not yet. The hatred simply exists, fully formed, from episode 1.
What the show hints at
The strongest clue is that they're opposites down to the bone. Ainsley is her mother in miniature — a party girl cut from Angela's cloth — while Cooper is pure Tommy: a workhorse who'd rather bleed on a rig than talk about his feelings. They even split over their parents, with Ainsley scheming to reunite Tommy and Angela while Cooper wanted no part of it.
Co-creator Christian Wallace told TV Insider in 2025 that the siblings clash precisely because they're polar opposites — and that he'd like to dig into the relationship further.
Even the actors don't know
Here's the fun part: the cast is as confused as the audience. Randolph admitted on the Today show on February 10, 2026 that she and Lofland — close friends in real life — have both called Sheridan asking for backstory to play, and never got one. Her working theory:
"They are mirrors for one another," Randolph said, explaining that each sibling stands for everything the other opposes.
Lofland has said much the same in a Paramount+ featurette during season 2: the on-screen hatred is pure acting, with nothing behind it but the scripts.
Will season 3 finally explain it?
Maybe. Both actors are confirmed to return, with Ainsley heading off to college — a storyline Randolph says she's excited about, since it takes her character away from the family dynamic entirely. Distance might thaw things. Or Sheridan might finally hand his actors the secret they've been asking for.
Until then, the answer to Landman 's most-asked sibling question is the strangest one possible: there isn't one.
