Jamie is a big man with an even bigger heart. Often soft-spoken, Jamie is a kind guy who wants to ensure he can care for those he loves. While he initially was nervous around the family he didn't even realize he had, the constant support he received from José allowed him to reconcile with Blondie and become a part of Sunny's life once more. Now, he's a proud father who tries his best to care for his entire family. 

Jamie should have a voice direction similar to Dwayne Johnson! Just like his son Sunny, Jamie is the kind of guy who wears his heart on his sleeve. He can easily show his emotions any time he speaks, and he sometimes doesn't even realize. You should be able to showcase this emotion in anything Jamie says, and also be able to showcase genuine nervousness, as Jamie gets nervous a lot at the beginning. Here's a link to an interview with Dwayne Johnson, showing his voice in a calmer fashion!
