"This is where the season is about to get incredibly interesting because each date she goes on she thinks, 'He's the one' and then she goes on another date. The fun and games are done, the window dressing is gone with [Travis Pope] and [Ryan Bowers], so from here on out it's guys she truly likes," The Bachelorette host toldTV Guide.
While Maynard has obvious chemistry with all her remaining suitors, Harrison said the relationships are very different from one another.
"[Arie Luyendyk Jr. and Emily] are definitely on another level as far as the chemistry goes and the passion. He was like, 'Oh look at the storefront window,' and then he throws her against the wall and they start making out! You go from that to [Doug Clerget] who she literally has to put his hand around her. But you see her with some of the other guys like [Sean Lowe] and [Jef Holm] and that's on another level too," Harrison explained.
Harrison admitted the only connection he believed Maynard had with Ryan, whom she eliminated during Monday night's The Bachelorette broadcast, was a physical one.
"It was such a weird elimination. Ryan being so confident and arrogant he almost convinced her like, 'No, you're not letting me go.' I think she realized, 'Yes, I'm attracted to him, but this is not what I want to end up with anymore,'" Harrison told TV Guide.
"It was a big hurdle for her to realize this is not right because she's very attracted to him and a part of her wanted to say yes, but she has too many good guys here. He went from the bad boy to the annoying boy and what really did it was the list of qualities he's looking for not including family. It really put her off."
Although it wasn't much of a surprise to Harrison that Maynard sent Bowers home because of his forward and "arrogant" personality, it did apparently shock him and the other producers that Maynard chose to eliminate both men who went on one-on-one dates with her this week.
"Well, we were thrown for a loop that she sent both Travis and Ryan home," Harrison said, adding that it seemed right to give Maynard an extra rose during this week's Rose Ceremony so both Clerget and John Wolfner could stick around longer considering she had already made multiple cuts earlier.
"When she decided to clean house it was a little easier of a decision, and also when she came out she was so serious and her instincts are so good so it was easy for me to say OK."
In addition, Harrison teased what viewers can expect to see during next week's episode of The Bachelorette -- including how the story of Luyendyk Jr.'s prior relationship with The Bachelorette producer Cassie Lambert unfolds.
"Next week is the most romantic week, but also very intense. Emily does find out about the relationship Arie had with our producer and we deal with that. It's very straightforward, we show clips and raw footage, we just show viewers what we have and the conversation that took place," Harrison said.
"It was a decision of whether we sweep it under the rug and act like it didn't happen? We want to show people that yes there was something there, but it wasn't the biggest calamity in the history of the show."
