THE BACHELOR - “2704” - This week, Zach and the remaining women set off on their international journey to find love, starting off on the romantic beaches of The Bahamas. First up, Zach sets sail to explore the world’s largest underwater sculpture and see how deep his connection with one lucky girl can grow. The next day, Zach invites the women to a fish-fry party, but drama bubbles up when one woman refuses to let someone steal him away. That night, after learning one person may not be here for the right reasons, Zach addresses his concerns head-on. Later, Zach ventures out on his second one-on-one on a wild ATV ride through the forest on “The Bachelor,” MONDAY, FEB. 13 (8:00-10:01 p.m. EST), on ABC. (ABC/Craig Sjodin) ZACH SHALLCROSS

Zach Shallcrossmay have had30 women vying for his heartat the start of hisBachelorjourney, but he is confident he has found the one.

Ahead of Tuesday’s Women Tell All special, when Shallcross will face his exes for the first time since sending them home, the Bachelor exclusively tells PEOPLE he is certain about his final choice.

“I think it’s weird reliving it and watching it — it wasn’t pretty all the time and it doesn’t get very pretty at later stages,” says Shallcross, 26. “But all in all, call it cliche, but I truly do believe everything did happen for a reason.”

He adds, “It couldn’t be perfect to get to where it’s at in the end — and it may or may not have made it better or stronger at the end. But I do feel confident. Very confident, yes, absolutely. I’ve got a big grin on my face.”

As for Women Tell All, Shallcross admits he was “very nervous” going into the night.

Though he is “not a big fan of public speaking,” Shalcross was hopeful the night would be a “great opportunity” to give himself and the previous contestants closure.

“I think my heart was beating through my throat like when I was just seeing everyone because it’s been literally since doing the show since I’ve seen them,” he says. “I have no other other remark other than it was just kind of like those nerves of, like,night onecoming again.”

He continues, “All these beautiful women that are my exes are now staring at me and may or may not like me. Honestly, it was a cool experience, though to get to see them again.”
