This blindfolded trust training exercise was the opening scene for The Black Vipers for a reason
Because as much of a reliable, stalwart rock he serves as and as much of a patient, out-of-the-box thinker he is, Clay can lose sight and lose perspective. He can leave people behind and charge ahead without noticing who he hurts because he's heading towards a goal
When there's a way things are, that's how they are, when there's something to be plowed, you plow it, when there's somewhere to be, you go there
Clay's never malicious, but sometimes, in the pursuit of goals, in living the way he feels he's supposed to live, in accepting the limited comforts he has at his reach, he can overlook the things he may have accidentally dropped or trampled while being a good and proper Texan boy
And there are shades of that in his relationship with Jesse too
"You never told us you had a sister."
"Would you want people knowin' you were related to a no-good varmint?"
"You think I'm a varmint?"
"You never understood what it was like growing up in the shadow of such a perfect older sibling."
"Oh, not this ol' saw again."
"Ma and pa always thought you were the pick of the litter. And whatever I wanted, you got!"
"Well, you know I only got things first 'cause I was the oldest."
The usually-perceptive Clay is very obtuse about their upbringing. Because Daddy Bailey did expect the most from Clay because he liked him best-- something Clay suffered from, but Jesse suffered from too
Clay did not just get certain things because he was "older". "Whatever Jesse wanted" were often things she was never going to get, because they were reserved for Clay.
Like the Lone Star family heirloom. Or a trip to a study abroad to get away from the Bailey Ranch. Clay didn't get those for being older, he got those for being Clay
And "this ol' saw" is a discussion they've had time and time again, because Clay has always shut down any claims Jesse makes about favoritism just like Jesse will always refuse to think that Clay ever had it hard with anything.
But part of the difference is that Clay often doesn't open up about his struggles like how he disliked having to be so subservient to their dad. Jesse's very vocal about her struggles; so Clay actively denies them to her face, and Jesse ignores the things she knows Clay won't ever say anything
The thing about the Bailey sibling's relationship is that, even though neither of them are at fault per se because neither of them had the power in their dynamic like their parents did, neither of them are blameless in each other's pain either. They've both hurt each other, and they've both refused to acknowledge the struggles or the perspective of each other,
they've both given up on the other because not only do they think they're beyond help but they also think that they don't need help and would never accept it anyway
It's a complicated dynamic. They're both complicated, flawed people who love each other as much as they resent each other
