Doc Holliday and Raleigh Becket
It had been his brother who taught him that being cocky wasn't exactly the best thing to be. Though, it took losing him to change how he reacted to things and to people. Changed how he viewed certain things. There's a part of him that will always feel guilty for his brother's death but that wasn't a road that needed to be ventured down. Not when no one would understand that they were in each other's heads when it happened.
"Family is everything." Raleigh himself didn't have a spouse or child but he knew that family meant a lot. "I'm sure you'll do just fine by your daughter."
