"You're going to be getting a lot of answers to a lot of questions you didn't get in The Bachelorette and Tia's and my relationship," Colton toldThe Sioux City Journal. "There are also a lot of unexpected emotions that are brought up."
He added, "At the end of Paradise, you will know where Tia and I stand."
Colton and Tia briefly dated in January, before Arie Luyendyk Jr.'s season of The Bachelor began airing on ABC. However, the pair called it quits on their budding relationship due to bad timing, long distance, and Colton's casting on The Bachelorette.
Once Colton made Becca aware of his former fling with Tia at the start of The Bachelorette season, Becca decided to pursue the charity founder only after receiving her good friend Tia's permission and genuine blessing during a Week 3 group date.
Slowly over time, Colton grew to be "in love" with Becca, and she even met his family.
But Tia made another appearance on The Bachelorette's July 16 episode to inform Becca she still had feelings for the former professional football player and it made her feel "sick to [her] stomach" to picture Colton and Becca together.
Following Tia's shocking revelation, Becca sent Colton home.
As shown on Bachelor in Paradise's Season 5 premiere, Colton and Tia reunited in Paradise and embarked on a romantic date together in which they went jetskiing and sailed on a yacht.
The couple obviously cuddled and kissed, but Colton wasn't sure whether he wanted to continue a romance with Tia or just find some closure.
"It helped me to grow as a person. What I learned I'm going to apply to my next adventure in life... The reward is greater than the risk," Colton said of his experience in Mexico, adding that his time on Bachelor in Paradise didn't come without hardships.

"The biggest thing in Paradise is you're watching other relationships form. So as you're trying to develop your own, you're seeing others' and you're gauging yours against theirs. For me, that was a little difficult: 'Why am I not like that yet? What do they have going on that I don't?'"
Based on previews for the rest of the Bachelor in Paradise season, Colton is going to have a little bit of a meltdown and break down into tears.
It's just unclear at this point what exactly is going to make Colton so emotional when he's supposed to having fun in the sun.
