Bachelor in Paradise's seventh-season cast, including Ivan -- who originally competed on The Bachelorette's sixteenth season last year -- had to evacuate their resort in Mexico and stop filming for one night due to a potentially dangerous tropical storm.
When Wells confronted Ivan on Tuesday night's Bachelor in Paradise episode, Ivan admitted he had spent time with Alexa in her hotel room when the cast was supposed to stay in their assigned rooms and follow protocol.
According to Wells, it was actually Alexa who "broke down" and "spilled" the beans about Ivan breaking the rules to visit her in the middle of the night, when Ivan's roommate Noah Erb claimed to be sleeping, Us Weeklyreported.
"A producer was next door to [Alexa's] room. She heard people talking late into the night," Wells revealed on Wednesday's episode of his "Your Favorite Thing with Wells & Brandi" podcast.
Alexa, an esthetician from Chicago, IL, who competed on The Bachelor's 24th season starring Peter Weber, was staying at the hotel because she was scheduled to appear on Bachelor in Paradise soon.
"[Alexa] obviously [is] quarantined away from everyone, [and the producer was] like, 'Who is this person talking to? What's going on?'" Wells said.
"How we found out about it was she called and asked for a wake-up call at, like, five in the morning. When we found out about that, we were like, 'What is she waking up for? She's not going to set today? Why are you getting up at five in the morning?' -- We heard voices, wake-up call, like, what's going on?"
Ivan told Wells he had been hoping to meet Alexa in Paradise and found a producer's phone in his room with an alleged screenshot of the cast's different room numbers.
"Yeah, to be quite frank, I saw it. I saw Alexa's name," Ivan replied, adding that he had made a super impulsive decision to meet up with Alexa that night.
Ivan elaborated during his tense conversation with Wells, "We were talking on her balcony and we hit it off... It was wrong of me. I shouldn't have gone around the system. My mind was just in a weird place... Love makes you do, like, weird and crazy things. I made a mistake."
On their podcast, Brandi Cyrus asked Wells to clarify how Ivan could have just stumbled across a producer's phone with Alexa's room number on it.
"You get taken to a room... [and] you're stuck there. You're not allowed to leave the room, they take your keys away, you're just stuck there," Wells explained, according to Us.
"So if you ever need anything, the producer has to come and give it to you. So like, 'Hey, we need some chips and, you know, a case of beer and whatever,' producers have to come and bring it to you."
Wells therefore believes a producer had spent some time in Ivan's hotel room.
"We're all friends, we're working on a show together, everyone knows each other -- and so I think what happened is that a producer had everyone's room number on their phone. And because you have your mask, and your phone doesn't read [your face], she had turned off her face notification, so she could get to, like, all the information," Wells claimed.
"And so she left the phone in the room. I think [Ivan] went over and was like, 'Oh, here's a phone,' realized it opened up and the first thing was everyone's room number. And then he bailed."
Wells also suggested to Brandi that Noah was lying when he claimed to have fallen asleep that night following a brief conversation with Ivan.
Wells, in fact, said Ivan's roommate "knew a lot more than he let on."
"I don't know this for a fact, but like, Noah, you would have to know that someone's gone. You know your roommate's gone," Wells noted.
"But I still maintain that that was a pretty insane thing that happened because a lot of things needed to happen."
Wells went on, "The hurricane needed to happen, we had to take everyone over there, a producer had to leave a phone in the room, he had to see the number, he had to go over to that room, he had to hang out there, he had to completely not say anything about it, then hook up with [Chelsea Vaughn] the next day, then get called out for it all within 24 hours."
Wells revealed that he had no time to prepare for his pre-Rose Ceremony confrontation on the beach with Ivan.
"I remember getting ready for the Rose Ceremony. And there was, like, a lot of powwows going on with production. And I'm like, 'Guys, what is going on?'" Wells recalled.
Wells said he had been given "an entire script" of things he was supposed to say when addressing the cast ahead of the Rose Ceremony.
"You know, 'How's everyone doing? I'm seeing love here. It's so beautiful.' And I learned this entire script -- this happened to me so many times this season, by the way -- I learned this entire script and they're like, 'Scrap it. We're going rogue,'" Wells explained.
"And I was like, 'What does that mean?' And they're like, 'Just go ask Ivan to talk. He's got something to tell you. Something happened last night, when everyone was back at the [hotel].'"
Wells disclosed that Ivan proceeded to unload his story and there was "a lot" more to their conversation than what was shown on Tuesday night's episode.
Ivan apologized to the other bachelors and bachelorettes for going around the system, and he ultimately left Paradise alone and single.
"I don't want anybody to feel bad for me at all," Ivan said in his final words. "I made a choice and I have to own that choice, and I'm going to continue thinking about this and regretting it, and I'll live with this the rest of my life."
Following Ivan's departure from Paradise, Alexa never made it on the beach.
It therefore appears the couple's sneaky tactics ruined both of their chances to find love on the show.
The finale of Bachelor in Paradise's seventh season is set to air on Tuesday, October 5 at 8PM ET/PT on ABC.
