I never really see these 2 as shipping when they're together. I have a lot in common with Applejack while my mum is somewhat like Rarity (minus the drama queen part). So whenever I see these 2 ponies together I would imagine seeing myself and my mum spending time together - back when we still lived together. Thank you for sharing this, it really makes me happy.
I suppose that giant crystals don't give the best shade.
Anyway, she's a marshmallow based life form, not carbon :3
