The 150th episode of Hawaii Five-0 paid some great deal of attention regarding Doris and Steve's complicated dynamic. But it also brought some closure to a thread that's been dangling for well over a year. Ruining McGarrett's cozy home-cooked dinner date with Lynn, Catherine Rollins (Michelle Borth) broke into the scene to convey the news that Doris has been captured and imprisoned at a CIA black site in Morocco in an effort to try and spring Wo Fat's father.

Catherine giving some hints

As Steve was busy preparing to launch a rescue operation, Catherine made some wonderfully awkward small talks with Lynn, who slipped on giving some hints that a marriage proposal was imminent at the time Catherine bailed on Steve just last season. Catherine made it clear that it was not much of a big deal upon hearing that she had completely missed out on a proposal, though the topic eventually came up after the rescue for Doris was successfully pulled off with help from Kono, Chin Ho, and Grover.

O'Loughlin's thoughts

When Catherine admitted to Steve that she knew all about the proposal, why did he even push for what her answer might have been? According to Alex O'Loughlin, "I think it's an important piece of information. I mean, wanting to know it out of curiosity is one thing, but I also think he wants to hear her say, 'It wasn't you, and you weren't the problem. I was.'"

More to expect from the new Episode

Indeed, as speculated on the new episode, the former couple's discussion of this is a very delicate piece of personal business that came just in time as Catherine was about to flip to yet another covert assignment, which is also one that she didn't give any thought to bailing on, even after she admitted that she would have said yes towards being his wife.
