From the interview....
ET: How do you compare what Frank did to what Justin did? Do you think they are the same thing, or a world of difference?
Ali Fedotowsky: I think there are similarities, but I think they are not in the same category at all in terms of if I had to put them in buckets. I think Justin's was more manipulative. Whereas, I think Frank was with this girl before he came on the show and I think they basically split up for him to go on the show. I don't think the feelings ever left. I think when Frank came on the show, he didn't expect to have such strong feelings for me. When he did, he was, "Oh, crap. I still have feelings for the girl back home." He should have come to me sooner. I think he knew all along that this was how it was going to play out. I don't think he wanted to be the last one standing. I think he was, "I am crazy about her, but I hope she sends me home next week. I hope I get really far and then she sends me home." When he got into the top three, he realized, "This could be it. I better say something."
ET: Do you know why Frank and Nicole broke up in the first place? I guess what I am asking is did you get more clarification beyond the conversation we saw on the air?
Ali Fedotowsky: No, I didn't. I really knew nothing about her. I knew something about another ex who went to Paris with him that he told me about in Iceland. I asked if he still had feelings for that ex because it seemed as if he was still holding in some feelings for an ex. I asked him about that particular ex that went to Paris and he said, "I don't have feelings for that girl anymore." So, little did I know not that girl, but this other girl that he failed to mention. I will talk to Frank at the "After the Final Rose" ceremony. I think it would be nice to get some clarification with what happened with that relationship. It would be nice to know in order to close it out.
