Those two couples reportedly join the franchise's first-ever, same-sex couple of Demi Burnett and her girlfriend Kristian Haggerty, whom Carbone had previously reported got engaged on Bachelor in Paradise this season.
Season 6 will tie the record for most engagements in a Bachelor in Paradise season, as Season 3 of the series also ended with three engagements.
Dylan, Hannah, Chris, Katie and Demi were all members of Bachelor in Paradise's original cast when filming began, meaning they all arrived in Paradise on Day 1 ready to date.
Dylan and Hannah paired up immediately and exchanged roses all season long, according to Carbone, while Chris and Katie only got together at the second Rose Ceremony of the season when Katie decided to give her rose to Chris.
As for Demi, she allegedly exchanged roses with Derek Peth at the first two Rose Ceremonies before revealing to cameras she's bisexual and then Kristian, whom Demi had already been dating for several months, showed up to Paradise.

Of all three couples, Carbone predicted Hannah and Dylan will last and actually get married considering their relationship in Mexico was sincere and neither person strayed during their time on the show.
Hannah G., a content creator and model from Birmingham, AL, competed on Colton Underwood's edition of The Bachelor earlier this year before making her way into Paradise.
Hannah G. made it to overnight Fantasy Suite dates but was dumped before she could enjoy the night with Colton because he had his heart set on Cassie Randolph.
Dylan just appeared on Hannah Brown's season of The Bachelorette. The tech entrepreneur from California didn't make it as far as Hannah G. her The Bachelor season, as The Bachelorette star Hannah Brown sent Dylan packing during the Rose Ceremony that was held in Riga, Latvia.
Demi was also a bachelorette from Colton's The Bachelor edition. She finished in ninth place and made waves in the house with her expressive and forward personality as well as her confidence.
Demi's partner Kristian will be a stranger to Bachelor Nation when she shows up on the new season, but sparks were reportedly flying between the women before the show began filming.
Carbone heard Demi is bisexual all the way back in January when Colton's season was airing. Carbone claimed to have received pictures of Demi kissing another woman, but he had no intention of outing Demi at the time.
Demi reportedly met Kristian through fellow The Bachelor contestant Catherine Agro, as Catherine and Kristian were roommates. Demi and Kristian allegedly began dating in February.
As Carbone was prepping his spoilers for the new Bachelor in Paradise season, he heard Demi had a girlfriend whom she was planning to introduce to the world on the show. Carbone later received confirmation Demi's girlfriend left for filming.
Carbone says Demi and Kristian were given a Date Card once they reunited in Paradise and then Kristian got to stay on the show.
"All this of Kristian coming on the show was pre-planned," Carbone wrote in a June 18 blog posting.
"Demi talked about it with producers, she knew Kristian was gonna be brought in after filming had started, and she wanted to use the show as an outlet to come out as bisexual. They're not having Kristian battle over other men for Demi or anything like that. They are there and they are a couple."
Carbone said at the time Bachelor in Paradise will be The Demi Show for a while and producers and Demi will both exploit her given she and Kristian are the franchise's first-ever same-sex couple.
"You can bet your ass ABC loves this and will scream it from the rooftops how ground breaking it is for their show to have a same sex couple on it," Carbone wrote last month.
"That's why they're allowing it and seemingly not caring about any sort of rules for the show."
Derek reportedly wasn't completely blindsided by Demi's relationship with a woman.
"I guess there had been talk either before the show or on the show by Demi that she had dated women in her past," Carbone said last month.
"I don't think Derek physically expected Demi's girlfriend to show up during filming, but I don't think he was all that shocked by it either when it happened... I think the seed was planted so he wasn't completely caught off guard."
