ABC released a promo last month that showed Hannah making a surprise visit to see Peter -- who finished in third place on her The Bachelorette edition -- while he was filmingThe Bachelor's 24th season, which is set to debut Monday, January 6 at 8PM ET/PT.
"I'm making decisions for my heart, because I know there's still something there," Hannah replies. "And I would do anything for a relationship."

The pair's body language suggested there was potential for reconciliation, especially given Peter leaned in close to Hannah and nearly tried to kiss her.
Peter then apparently proceeded to invite Hannah to become one of his Season 24 bachelorettes.
"Hannah Brown, what I'm about to say is extremely crazy. What would you say if I asked you to come and be part of the house?" Peter asks Hannah as he rubs her back and she giggles.
Women were shown eavesdropping in on the conversation from a distance and yelling, "Oh my God!"
And in a second promo for the new The Bachelor season that aired later during the Dancing with the Stars broadcast -- which concluded with Hannah being crowned champion over three other finalists -- Hannah stepped out of a limo at the show's Malibu mansion.
According to Reality Steve spoiler blogger Steve Carbone, The Bachelor viewers shouldn't read into the promo of Hannah and Peter's reunion too much.
"B4 everyone freaks out... Hannah WAS NOT a contestant on Peters season," Carbone tweeted late last month.
Hannah playfully asked her runner-up, Tyler Cameron, out on a date during The Bachelorette's live reunion special since things didn't work out with Jed.
Hannah and Tyler spent one night together in Los Angeles, but then Tyler moved on with supermodel Gigi Hadid, whom the former Florida contractor dated for nearly two months before calling it quits on the relationship in October.
