I'll tell you the key points that happen after the season. its might be inaccurate since its been a pretty long time since i read the novel.
(This is a longer version, for a shot summary scroll to the bottom.)
•After Dane drugs (with a large amt of drugs that can get any dom alpha unconscious) and kidnaps Greyson, and takes him to a helicopter. Greyson obviously passes out but obviously he's faking and Dane guessed that. Then Greyson realises he's on a helicopter and really high in the sky and starts hyperventilating and starts looking like hes on the verge of a panic attack and obviously Dane also panics because he didn't know that Greyson had a fear of heights—and remember that Dane thinks that Greyson was abused when he was young.
•Greyson says he cant do this anymore because hes deathly afraid of heights and throws himself of the helicopter, and when Dane grabs him, he pulls Dane down with him and starts laughing like a fucking psycho (I love Greyson but this was not it) Because turns out, he was faking it. He took some special pill that he uses to make himself look scared and nauseous in case he needs to escape from a kidnapping.
•Dane is baffled and absolutely angry and starts kicking the bitch that is Greyson. And Greyson is laughing and giggling like a kid while hes getting kicked in the sand—they were stranded in son desert thing in california. Dane thought he was gonna die with this stupid bastard so he gets more made. Turns out Greyson Dislocated his thumb to take off the handcuffs so that made him more made and made Greyson laugh even more.
•Eventually Greyson tells Dane that's theres a house nearby where his Daddy(Ashley Miller) Traps Papa (Conner/Koi Miller) Dane is initially confuse but goes with him.
(Im gonna try to make this shorter, i dont have an will power in me anymrle lol)
•Dane is sorta relieved and goes to take a shower and eat and he finds out that Grayson knew exactly when to stop the helicopter so he can trap Dane. And he LITERALLY traps Dane, meaning he used some remote thing that makes the bigass mansion go underneath the ground so they cant get out.
BTW Grayson and the other Miller siblings have a microchip in theres veins to track them when kidnapped, but when they go under this mansion under the dirt the microchios deactivates so nobody can find them.
•So Dane's mad AGAIN like bitch!! you better give me that remote Grayson, or im gonna kill your ass!! And Greysons like WHOOPSIE!! HAHA I BROKE THE SHIT. Ikr i literally was crying laughing, Grayson stomps the remote and breaks it so they can literally not get out. Dane punches Grayson (Honestly, this time my guy deserved it)
•So now they eat rotten bread and go to sleep.
•The next day the wake up and Dane finds out the have a freaking military food factory or smthg right next door so he was upset that he had to eat rotten fucking bread so he got mad at greyson again.
•Since he was mad he ordered Greyson to cook for him and Stupid Lil Greyson was like 'Me? Moi?? HUH??' And Dane is like 'YES BITCH YOUU!!!'. So frustrating does smthg stupid and just takes cans of plain chicken breast, Dane slaps him, gives him ingrediants to make soup or smthg and blah fucking blah. They cook, Dane pours beer over Greysons head because Greyson called him an omega again
•Later, Dane asks greyson whether he'll let him out and Greysons says he'll let him go when they have sex and Danes like 'yah, sure lets do that' and starts unbuckling his belt and then Greydon like 'NONONONONONO, I meant you as the bottom :)' and Danes like NO WAY IN HELL
•So another fight, yada yada. blah fucking blah.
•At night, Dane ends up going into hes—AND LO AND BEHOLD, HES AN OMEGA!! But he's a dominant omega so its not really that obvious that he's an Omega (BTW, Conner/Koi Miller, who is Greysons papa, is also a dominant Omega) So he looks everywhere for heat medicine since he knows that Greysons papa is the same dominant omega as him but he realises since Greysons PARENTS who r a very loving COUPLE stay here they're obviously having sex.
•So he goes to Millers room and has sex with him. Millers like, 'NONONONOOOO ,BITCH THIS IS RAPE!!' And Danes Lil 'BROO, YOU WANTED TO HAVE SEX!!' (Which is really a big red flag y'all, i was very fucking disappointed by this shit) Dane uses his pheromones to he Greyson in the mood and they have SEX Yayayay
SHORTS VERS:
•Dane kidnap Greyson. Greyson fakes a fear of heights, climbs out window, pulls Dane with him and they fight. Greyson takes him to a hidden mansion in the desert they're in and traps Dane by Using a remote to pull the Mansion beneath the ground.
•They eat and argue and next day they eat and argue again. And Grayson says he'll only let Dane out once he has sex w him and Dane HAS to bottom. At night, Dane is actually a dominnat omega and goes into heat cycle, they end up having sex.
BTW IF YOU WANT THE REST OF THE SPOILERS JUST REPLY TO THIS POST AND ASK
YESSS IT IS POND!!!!!! I LOVE THE SERIES SO MUCHH. And ofc i have time for spoilers loll
•After they have sex eventually grayson lets him out, cause that was the most mind-blowing sex his baby brain ever had. Grayson then forces Dane on a date.
•The next day, Dane just goes to check up on darling, whose in the hospitalnand baiscally just does his own thing during the date, because Dane never went on a date before.
•Theres a moment were Dane takes a contraceptive pill and Grayson gets mad for some reason cause apparently its not good manners to take a contraceptive pill in front of the person who just fucked you (which rlly does not make sense lol)
•And after that, Dane notices a large festival with lots of people and hes like 'oOOO Grayson would be all over that shit, why the fck is he so moody today??' Because he obviously doesnt know he hurt Greysons feelings.
•And then BOOM, the festival was actually a terrorist attack, OH NO! So an actually BOOM happens and bombs explode, every citizen around them is in panick, Grayson looks confused as well. Then Dane—who is a law-abiding fire fighter—was like 'I NEED TO PROTECT THESE PPL' And Grayson like 'NOO!! WHAT IF YOU DIE' While having a genuine scared expression on his face, And Danes like 'Everybody has somebody waiting for them at home, You have 6 siblinsg and a huge family. I have nobody, and person who has nothing will always save a person who has something.' Which is basically saying, My life doesnt matter compared to the lives of people who have ppl waiting for them at home.
•Grayson tries to stop him but Dane ignores him and goes towards the fire. Dane ends up calling the fire station but still goes in and evacuates all the people. The fire station ends up coming and it turns out to be a large terrorist attack so a large fire. It took a long time for Dane to get out and we have this heartwarming moment where greyson genuinely is scared for Dane.
And thats all I remember for now, I'm rereading the novel so istg i will finish these spoilers!!
Also heres the short vers:
•After they have sex, Dane takes a contraceptive, grayson thinks its bad manners and kinda gets mad. They end up have a date on par with Grayson's wishes. A huge festival is there at the place they were walking around.
•Bomb erupts and building start flaming, Turns out Festival was actually a terrorist attack, Dane goes in because he has nobody and hes willing yo sacrifice his life because atleast other ppl have somebody else. So a very sad moment.
•Grayson feels scared when Fire Fighters come and Dane comes out last. He's also a bit annoyed that Dane was sacrifice his life for regular citizens.

Someone please spoil for me
