Tour Jete, often goes by TJ, son of Rarity and Rainbow dash, is a professional ballet dancer and costume designer for the theatre he’s working at. He is also a part time teacher at a dance studio, mostly teaching hip hop.  
When he was younger, he started attending gymnastics (Rainbow still wanted her son to do something sport related). While he liked going to his classes, he didn’t quite enjoy his performances, especially in competitions. He felt like he was missing something. The only thing, that kept him going on was his mother Rarity’s costumes. She would create a new costume for every contest and performance. It wasn’t until Rarity took him to see ballet, that he truly discovered what he was missing.  
He also LOVES, whenever aunty Sapphire visits Rarity, to talk about new costumes.
