As for unfavorable edits:
QUOTE* Have all of the F1 winners been likeable? Have their edits reflected that? For the most part, yes. However, Helene (S2) had a somewhat unfavorable edit..*
Actually Helene's edit wasn't bad, she was edited like Trista, skeptical of the situation and wanting to leave. Aaron actually wanted to exchange phone numbers so he could call her if she decided to leave.
Sarah Stone was the first F1 to be shown using a curse word on the show. (She called the other girls **tches.
Deanna received the worst edit of the F1's, even though she didn't receive the last rose, she was considered the "winner". She was shown calling the girls **tches, being a bit bossy during her FD with Brad (the toilet seat convo), and taking over the converstation on her 2/1 date.
In the first season, Amanda was edited as "WILD", she and Alex (on their fantasy date) sprayed WHIP CREAM on the camera. She also openly spoke of a boob job to correct uneveness.
So Final 1 doesn't always get a PRISTINE edit, but she ALWAYS gets the developing story line. She's usually hidden during a few episodes and then makes a very clear connection on at least one episode.
To me the most obvious F1's have been Mary and Shayne. The rest of the seasons, the F1 has been a bit hidden.
