Rarity is quite intelligent, and furthermore appears to have the best grasp of social intelligence in the group. Displaying both a cunning wit and an insight into the emotional states of her friends, she is the only one to notice that something is wrong with Rainbow Dash in Sonic Rainboom and is quick to inquire about others, should they seem upset. She also displays one of the most complex and grammatically correct language of the cast, next to Twilight Sparkle.
