Alex O'Loughlin post-episode interviews
In a post-episode interview with TV Guide lead actor Alex O'Loughlin stated that the McGarrett and Rollins relationship "had now been finished the right way" and that "McGarrett would be an idiot to take Catherine back". When asked if there was hope for a romantic reunion between the two characters O'Loughlin stated: "The way she [Catherine] left things, it was pretty disgraceful. That being said, it does offer some closure for him. It's now been finished the right way. I just think if she [Catherine] came back and went, 'I'm available'... first of all, he [McGarrett] really likes Lynn. She's [Lynn] a great girl. And I don't think he [McGarrett] would just ditch her [Lynn]. That would be the wrong thing to do."

In a later interview with TVLine O'Loughlin was asked why McGarrett pushed for an answer on what Catherine would've said had he proposed he said "I think he wants to hear her say, 'It wasn’t you, you weren't the problem. I was the problem.'" and when asked if Catherine's hypothetical proposal answer should raise red flags his response was "Absolutely not. No f–king way,Catherine is not 'the one who got away' but 'the one who was not meant to be.'"
