I only saw the first few episodes of Ugly Betty back in the day, so I had no baggage, but I didn't buy him as a nice guy, just because Emma isn't allowed to be happy. I did sort of hope, if he did turn out to be from the EF, that he might just be a good guy, though. Mostly because it would be nice to have a man on TV say to a woman 'no, we're waiting on you, I respect your choices, I love you and will let you decide when you're ready' and mean it.

According to Wiki, he will be back, though so perhaps we'll learn more about him in the future.
