I felt that she was actually

No...I don't think so...

I think the fact he caller her freckles made her more insecure about his feelings for her, rather than jealousy ... i think Juliet was probably more upset ...

I thought when you insecure of someone's feelings it's called jealousy=)))

Jealousy is when you want someone to act the same around you as they do around someone else ... or want something someone else has. I don't think Juliet wants Sawyer to call her Freckles so i'm going with insecure. They're two totally different things, lol!

Jealousy is when you afraid that someone prefer someone else to you - the same as insecure=)))
Sawyer, calling Juliet Freckles is rocking, lol

You say tomatoe ... lol!
Well how ever anyone perceived the scene i guess insecurity/jealousy are very different yet exactly the same lol.
It's another frustrating quality the show has, to get so many viewers seeing all different things when they watch the characters! :-)

I know one thing, it was stupid and annoying when he said that.
