Art for art's sake

Okay, COLTLANDGENTRY!MOM SIDE OF THE FAMILY BACKSTORY TIME: Noah and Allie (non-canon obviously) had Holland. He grew up, got married, and had Holly. Canon lore states his wife dies tragically in a fire. The Nice Guys story happens when Holly is 13. A year or so later, he remarries to a Ms. Palmer and has twins Jacob and Sebastian and younger daughter Coltland!Mom (no name for her yet). Now, I haven't seen LLL to know Seb's family story (if there is one), but if we follow Jacob Palmer's canon-lore, he states he had a soft, kind father who died a while before Jacob's CSL story starts (which makes sense if Holland had them when he was older, he would have passed sooner into their lives). He also says that his mother was a vain, rich, beautiful, but cold woman. So I hc that Seb moves away pretty soon after that their father died, changed his last name to separate himself from the well-known Palmer name to make a name for himself, and has his LLL story. Their sister marries Mr. Meanguy Gentry. Jacob, despite his own womanizing, playboy ways, immediately picks up that Gentry is bad news, and claims that if she marries him, he'll never speak to her again. She ignores his warnings, and only ever sees Jacob after that briefly at family gatherings when he shows up to spoil his nephews (also why Jacob never knows about the abuse his sister and nephews are suffering until it’s too late). Sometime during all this, Holly marries somebody and has Ken (he's around the Coltland twins age and a lot like his grandfather).

COLTLANDGENTRY!DAD SIDE OF THE FAMILY BACKSTORY TIME: SO, coltlandgentry's dad (the bad one portrayed in The Gray Man) has three younger brothers, Driver and Luke (twins) and their younger brother Henry. All four of them were raised in terrible household, and, even as adults, the only time they could really spend time in the same room together without exploding was when they were visiting their young nephews (Driver (not his real name, I’ve seen some people hc Casey) is a stunt driver for movies, I hc this is what inspires Colt to become a stuntman himself). They also have a younger cousin by their father's sister named Lars (also a rough home life from what I've heard about the movie) that they bring around to hang out with Colt and Ryland sometimes. They live in this stale sort of truce for a few years (that Colt and Ryland remember as the golden years when their family was all together) until one day Henry and the parents are killed in a car crash. Then they all separate and have their respective movie stories (Driver was affected by this the most, as he was closest with Henry. Hence, why he's so quiet and violently unhinged in his movie while also having this sadness and loneliness to him).

As for Coltlandgentry themselves, after their dad's side of the family leaves, their mom dies under "mysterious" circumstances ("drug overdose" they said. Courtland knows it was their dad's fault somehow, but has no proof. This is when Jacob, Seb, and Holly start getting suspicious too). Then, soon after that, The Gray Man canon happens and Court finds their dad going too far in "disciplining" (aka, drowning) one of the twins (haven't decided which ones gets a fear of water yet), and shoots him. He gets taken to juvie, and the twins are sent to live with Holly (The Fall Guy extended version reveals Colt was raised by a single mother in Florida, so maybe Holly divorced or lost her husband before this). Then, a while after that, they get news that Court has "died" in a prison brawl (became a Sierra agent). The twins' resulting fallout argument is the last straw to make Ryland decide to move across country, change his last name, and start over. Colt takes the stage name Seavers for the same reason of distancing himself from everything that went wrong. A few years later, they eventually reconnect, spend a year together, then Colt has his accident, pushes Ryland away again, the 18 months ago by, The Fall Guy canon happens, but right before Colt can reach out to his brother after the dust settles, Ryland is selected for the PHM program and has very limited outside contacts. Only a few phone calls allowed, which he eventually uses to try to contact Colt for help when they try to force him onto the mission. Colt gets the voicemails too late, and by the time he realizes what's happened, his brother has already been sent on this suicide mission, never to be seen again.
