Explain how she’s holding the spoon.
Looks a little awkward, no?
The spoon is more or less inside the cup that her fingers and her palm make, rather than breaching it between the index finger and the middle finger akin to traditional Western silverware technique. One could argue the inherited awkwardness would be from the animation style itself, or more possibly the fact that Fluttershy’s character (as well as Spike) is well defined as being Left-hoofed/handed (See the hoof-rudding in the MLP:FiM introduction, as well as when she takes her bow at the end of the play in Hearth’s Warming Eve). Still, barring the translative differences aside when mirroring left and rightedness, the spoon still is being used as more of a gardening tool rather than the food consumption tool. Another possibility might be that the writers called for her spoon technique to be the demonstrated different style to subtly subvert the awkwardness of the scene itself, given Twilight’s response to eating the apple with her face. What I honestly hope for is that this action was intentional, but not called for in the script. What that would imply would be the apparent loss of editorial control and inherent authorship of the writer if an outsider, say a humble animator from DHX, could inject their own actions, symboles, and metaphors into the story that they are given. This might just be the most important frame of the entire film if that were the case, and dammit, I hope that is.
I haven’t actually seen the trailer.
They’re cartoon ponies
I honestly hope that you’re kidding and are merely ignoring the deep connotations that this particular scene could have on the entire idea of Author/Coauthor relationships in digital media/storytelling.
