@Disney Duster: Unfortunately, I do not live in the US and therefor all free, legal ways of watching the show online are not available to me. Fortunately, I have bought the first season on iTunes and I have seen all of the Storybrooke scenes in Hat Trick several times
I definitely see your point; however, I don't think she was really looking at the scar when she was trying to push him off of her. It's like, to use a tame example, when someone says something on a forum, you get very angry about it, and your goal is to reply and say something in return. Your not thinking about what the person might have really meant, or their reason for saying it, just that their words made you angry and you want to say something back. Emma saw the scar, but she didn't really think about it or compare it to what Jefferson had been telling her because her goal was to get him off of her before she or Mary Margaret got hurt.
As for whether her expression was because of the scar or the gun, I think it was both (should have clarified that earlier, sorry). She didn't say anything, so I don't think you can say without a doubt whether it was specifically because of the gun or not.
I still think something clicked between when Emma hit Jefferson with the telescope and when she saw Paige. Maybe it wasn't the scar, but his disappearing without a trace like he did, I don't know, but if she still thought Jefferson was completely insane, why would seeing Paige make her do something Henry has been trying to make her do for months?
Well, technically, I could say the same thing with you and Cinderella? I do understand your wanting them to deal with the fairy godmother differently then they did, but for me, it's not that big a deal. Depending on how you feel about the stories they're using, the portrayals of various characters are going to be different to everybody. Cinderella was never my favorite movie, while Alice in Wonderland is my favorite book. So while the way they handled the fairy godmother bothered you, it didn't bother me as much, while the beheading scene bothered me but didn't bother you as much. Does that make sense? However, I can see how my comparison wasn't very fair, and I apologize for that.
In any case, Sebastian Stan is set to appear in two more episodes this season
, so hopefully some things we've disagreed on will be clarified then.
