There were a lot of great (and not so great) expressions in S03E09, and I loved the look Rarity had after Spike broke the plumbing while trying to help out. Priceless!
Edit: Thanks to ~ShadowMark-182 for bringing to my attention that her mane was off. I added the horn which (ahem!) the animators totally forgot in this part of the scene. Comparison. Edit: 18 Jan - Thanks to pointers by *Mamandil I totally re-did the outlines and fixed some layering issues around the animation error. Way better AI/SVG file now.
When I noticed this in one of the scenes, Rarity's horn appears to be missing and I believe her mane was styled all the way on the right side instead of partly on the left side.
You know what? I think we can add that to the list of glaring errors in this week's episode. I just looked at the scene again, and her hair comes from the left side over her horn in every other part of that scene, but in this part, it's suddenly as you see in this vector. It looks like they put it on the wrong layer. I'm going to go back and fix it the way it was supposed to be!
