This was a very memorable moment in MLP, because it was really dark, maybe the darkest fragment in the entire show. And by the way, I felt a little bad for Spike, because I love the mother-son relationship that there´s between him and Twilight. Your pic is awesome by the way. The dark atmosphere makes its job and creates a feeling of sadness as well as Spike does. It´s a shame we never saw this scene, Spike just described it.
