Which 'Eclipse' scene is the from??

I love this BTS image, but what Eclipse (possibly NM) scene could it be from??? My only guess (and it's a stretch) is the "Anne of Green Gables" vision Bella has of how Edward was as a human. My first instinct was to think it was the first hunting trip in Book 3 of Breaking Dawn because it's a blue dress and they're in the forest running, but then reality set in. They're not filming BD right now. (Duh!) Plus, the vest kind of gives Edward away as a 1900's bloke. Big question mark here, but I love to see the two frolicking LOL

Which scene do you guys think this is? I know we can figure it out if we work together!

Bc Out!
