He somewhat came down to earth after opening up to his co-workers about the untimely death of his young daughter Harper.He immigrated to New Orleans, Louisiana when he was two years old. His family changed their last name to Marcel because it was popular in the region they were in and changed his name to Crockett because his father was a fan of Miami Vice and named him after the character Sonny Crockett. The family spoke Farsi at home, allowing him to become fluent in it, and overtime he built up a Southern Cajun style accent fluent around the Gulf Coast. He had a daughter named Harper who died of Leukemia shortly after her first birthday. Crockett donated bone marrow in an attempt to save her, but it was unsuccessful. Her death left a deep scar on Crockett and likely caused him to develop his cavalier attitude to life and his work, making him prone to taking risks and disinclined to form close relationships with those around him.When Natalie Manning finds out about his daughter, he implores her to keep the knowledge to herself for fear of people looking at him differently.
