Joe went through the motions of second-guessing his decision to appear on the spinoff and potentially wanting to quit Paradise due to his memories with ex-girlfriend Kendall Long on the same beach in Mexico.
During Monday's episode of "The Viall Files" podcast, Nick reasoned how ABC may be positioning Joe to star on The Bachelor's upcoming 26th season in 2022.
"[Bachelor in Paradise bartender Wells Adams] was on here recapping, and he mentioned that he thought someone could get a Bachelor edit from Paradise," Nick, 40, recalled.
"I'm almost certain that must be 'Grocery Store Joe' from what we're seeing in Episode 1."
Wells, 37, appeared on Nick's podcast earlier this month and revealed how there's a real gem onBachelor in Paradisethis summer.
"I think that there is one particular person that everyone is going to want to be the Bachelor," Wells continued, "and whether or not they are even available to be the next Bachelor at the end of it remains to be seen."
Wells went on to confirm Paradise has a Bachelor candidate by adding, "There is a big star in Paradise this year."
And Nick apparently agrees.
"I loved Joe this episode," Nick said on Monday. "I thought there's a real honesty and earnestness."
Joe seemed to spend hours on the beach by himself just contemplating whether he should proceed on the show or go home. He felt a little out of place and wondered if he fit in.
A couple of cast members, for instance, poked fun at Joe's outfit of choice, with Kelsey Weier joking about how Joe should be nicknamed "Gym Joe" because it looked like he just came from the gym in his plain T-shirt.
"You could see him really struggling. I think it's very relatable," Nick explained.
"I had feelings like that when I went back on Paradise for my [third stint on reality TV]. I was thinking, 'This is probably a stupid idea.'"
Joe and Kendall lived together and had been talking about marriage and kids prior to their breakup.
When Joe entered Paradise, he had his eye on Serena Pitt, 23, but she was a hot commodity and the pair had a bit of an awkward but playful exchange.
"You wanna know the truth? My conversation with Serena P. was like talking to Kendall," Joe admitted in tears. "I think I thought this was going to be fun. I did it before, but now I don't know if I want to do this. It's weird. I probably shouldn't have come back."
But just as Joe was about to quit, Serena P. sat down with Joe for another conversation because she had initially felt "fiesta flutters" for the bumbling bachelor.
Joe shared with Serena P. how his breakup with Kendall was mutual because they couldn't agree on a city in which to live long-term.
"We were also growing apart with certain things," Joe revealed.
Joe and Serena P. shared a sweet kiss on a daybed on the beach, and then Joe's mindset seemed to shift to a happy and optimistic one.
"I'm starting to develop feelings for Serena. It does make me want to stay. Yeah, I'm happy I'm here," Joe said with a big smile.
