SHAW PACK POLY!HC'S:
Okay, so, starting out with the Shaw Pack, it all starts out as usual with each of the partners getting together when they did.
THOUGH!
David had a one night stand with Baaabe and Asher before he started dating Angle.
But, back to (slight) present, who starts the poly stuff first, is Sam and Darlin' they both realize that they have developed feelings for David and Angel (Sam for David first, Darlin' for Angel first, then later (for Sam), both). It takes 'em a while, like, a WHILE, to confess, which they only did when Angel confronted them because they were catching on to 'em (Angel spoke with David before confronting 'em). Durning the confrontation, Sam confessed first, the Darlin' begrudgingly also confessed. They took it slow, but eventually started dating, mostly keeping it on the DL, only really telling Asher, Milo, and their mates.
Then its Asher and Baaabe realize, hey! We still really like David! (Asher for a while because I HC that he and David had tried 'dating' in the past, but broke up when Gabe died and they had to assume new roles). Asher and Baaabe confesed eventually, maybe a few weeks so they could talk it all out, before confessing to David. After those three got together, Baaabe and Asher started to date Angle too.
Then, a bit after that, a long bit (months honestly), Baaabe started to date Darlin', and then, eventually, Darlin' started to date Asher. And soon after that Asher started to date Sam.
Then last, but not least, Milo and Sweetheart! They enter the polycule through Angle 'n Darlin', Angle and Milo, and Sweetheart and Darlin'. Then eventually, they get with EVERYONE else (tsk tsk greedy greedy ppl shm/j).
So basically (organized by when they got together):
David: Angel, Asher, Baaabe, Sam, Milo, Sweetheart.
Angel: David, Asher, Baaabe, Darlin', Sam, Milo, Sweetheart.
Asher: Baaabe, David, Angle, Sam, Darlin', Milo, Sweetheart.
Baaabe: Asher, David, Angel, Darlin', Milo, Sweetheart.
Sam: Darlin, David, Angle, Asher, Milo, Sweetheart.
Darlin': Sam, Angel, David, Baaabe, Asher, Milo, Sweetheart.
Milo: Sweetheart, Angel, David, Asher, Baaabe, Sam, Darlin'.
Sweetheart: Milo, Asher, Angel, Baaabe, David, Sam, Darlin'.
