Emily uses the word "perfect" for Sean an awful lot. Perfect = "I should be crazy in love with him, but I 'm not." Sean would make an excellent Bachelor lead, IMO, but rumor is that somebody else has been chosen already (I assume that hasn't been discussed here).
I really didn't like Jef at all initially. Hate the hair, and his dropping of the 2nd "f" bothers me. Kind of pretentious, IMO. And according to a yearbook photo I've seen posted, he used to have 2 f's in his name. Anyway, I have grown to really like other parts of his personality. I love that he is so in touch with his inner child. Sort of like what freefragrance was saying above. He is very playful, but appears to be mature when necessary. He also appears to be good-natured and gets along well with others. If Emily chose him (and vice versa), I hope he didn't just get caught up in the producer mind games and only thinks he's in love with her. Same for Arie and Sean. I have this feeling that Arie is just playing a part, though. I didn't think so at first, but lately I have been. And Emily could be in on it. Maybe it's because the sparks that were so hot at first seem to have fizzled a little. Or is it editing?
