I got to agree the scene between Emma and Hook in the last episode was heartbreaking. Brutal and just devastating to see as a whole when you see just how far they have come and now this tragedy.

Yes. The town line.. It broke so many hearts with that one single tear that dropped from Robin’s eye..

Jen – as difficult as that scene was to film, it was equally difficult to watch. Both she and Colin obviously put their heart and soul into that episode and it really paid off. Everyone I watched it with had tears in their eyes. Bravo!

Imagine crying over and over, same scene for hours! Poor Jen!

I love when the cast comments on scenes they’ve filmed and their characters head space. The scenes that both Dallas and Morrison mentioned were also difficult as a viewer to watch (well for me) so I’m not surprised they were emotionally hard to film especially knowing how many hours go into scenes like that.
