Next Monday is the big reveal on "The Bachelortte" when Jillian Harris picks her man. The final two are Ed and Kiptyn, but there could be a twist in the finale!

From the promo that ran after last week's "The Bachelorette: The Men Tell All," it appears as if one of the past bachelors -- possibly Reid -- returns to get another shot at being the chosen one.

So what can Jillian say about who returns and what happens?

"I can't really tell you too much," Jillian tells ET. "I can tell you that when I watched the tease for the finale, even though I was there and I experienced everything, they did…. It is an exciting episode and a crazy day. I can't tell you who comes back, but it is all very traumatic, unfortunately."

That said, Jillian does rate the final three men: "I would definitely have to say for Reid, it would be his sense of humor and just his quirkiness. I would have to say that Kiptyn is just so genuine and has such a huge heart. With Ed, I would have to say it is his balance. He has a good balance in life between personal, business and family. He is a very well-rounded individual."

Even so, Jillian does have second thoughts about immediately getting engaged, and she talked to her dad about it. He told her that accepting a proposal from the man of her choice did not mean that she has to walk down the aisle immediately. He pointed out, "Getting a proposal in this scenario signifies for me that you are ready. Let's have a proposal, get engaged and start a life together and a year from now see where things are at and then get married."

"My dad was very right," Jillian says.

And if any of these guys turns out to be Mr. Right, Jillian has a picture in her mind of her perfect wedding: "I have this dream wedding of being somewhere in the Canadian Rockies, or in the Okanagan in a field and there are mountains all around us," she describes. "There are gingham tablecloths, maybe like white and red checked. There is a live band, hopefully, the Nitty Gritty Dirt Band and tons of people, but nothing really fancy. I am talking cabbage rolls and ham that my Auntie Becky would probably make and lots of kids running around. Down to earth and nothing over the top."

"The Bachelorette" finale airs Monday, July 27 at 8 p.m. on ABC.
