Understanding
Sam embraced his son and could not believe how blind he was to the entire situation. He was tearing his family apart with his dedication to work and knew that at that moment he needed to be a better dad. He was going to change for the better and be more hands-on.
But firstly, he was just so proud of his son for doing the right thing and knowing how to behave in a potentially risky situation. Sammy kept calm and collected and evaded the stranger who had suspicious intentions toward him. It was a terrifying, but also an incredibly relieving moment for Sam.
