6 years ago, Searing Bolt's parents were Killed in a construction accident, leaving Him and his older brother Burn, orphans. Years later at Burn's wedding, Bolt decides he needs to move out and give his brother and new sister-in-law their needed space. After talking it over with his brother and much protest from his sister-in-law, they came to an agreement that he could move out after his 18th birthday, but an accident in school forced him to move earlier than expected. After discussing it over with their aunt Celestia, Burn decided it would be best for Bolt in a calmer environment, Canterlot High.
This story came to me while going back and listening to Under Pressure by Logic, it's been in my head for a while but couldn't figure out what attitude I wanted Searing Bolt to have in this story.
