"The writers have a tough job... I always have the utmost respect for people who write series... So far [the relationship] is great. You've got to keep working on it though. You have to keep thinking of new and interesting things. We can't riff off the same stuff episode after episode." - Scott Caan, Zap2It, 2010
Caan also revealed that Danno and McGarrett's friendship evolution was directly inspired by his real-life relationship with O'Loughlin, confirming writers drew from authentic chemistry.

By 2018, a spinal injury nearly caused him to quit after accumulating herniated discs, nerve damage, torn shoulder muscles, and torn bicep tendons from stunts.
Throughout these health crises, Caan remained a steadfast support system. Their shared Brazilian Jiu-Jitsu training became therapeutic, with martial arts helping O'Loughlin manage chronic pain while Caan provided encouragement during his darkest moments when producers considered replacing him.
