Twilight and Rarity have a very healthy relationship. They work through their problems, by chatting and through practice. Twilight's worried about trying a new food? Rarity will order it and let her nibble. Rarity stressing that she can't think through a new design in time for her latest collection? Twilight will be her helpful rubber ducky, and listen.

Twilight has morning wood and feels awkward about it? Rarity will have it very well handled.
