[Warning: The following article contains major spoilers about Friday's episode of Hawaii Five-0. Read at your own risk!]
Hawaii Five-0's 150th episode may not have given McGarrett-Catherine fans the romantic reunion they had hoped for, but it provided McGarrett (Alex O'Loughlin) with some much-needed closure about the way their relationship ended.
"It's now been finished the right way," O'Loughlin tells TVGuide.com.
Catherine (Michelle Borth) comes back into town to tell McGarrett that his mother Doris (Christine Lahti) was caught trying to break Wo Fat's father out of a CIA black ops site in Morocco. The two embark on a rescue mission together, leaving McGarrett's girlfriend Lynn (Sarah Carter) to enjoy a romantic dinner for one. Awkward!
Once the action-adventure part of the episode is out of the way and Doris is safe and sound, Catherine (who, earlier, learned from an unwitting Lynn that McGarrett was on the verge of popping the question when she disappeared) tells McGarrett that, although she would have said yes to his proposal, she wants to put her career first for now and she's happy that he's moved on with Lynn. And then she's off again.
TVGuide.com chatted with O'Loughlin about where McGarrett and Doris are going from here, whether the serial killer storyline will come back into play, and why McGarrett would be an "idiot" to get back together with Catherine.
Hawaii Five-0's 150th episode gives "closure" to McGarrett
Switching gears to Catherine, she gives McGarrett her blessing about his relationship with Lynn. Based on that final scene between Catherine and McGarrett, is there any hope for them to reunite?
O'Loughlin: I have no say in what they write, but if you're asking me what I think, McGarrett doesn't need Catherine's blessing to do anything. The way she left things, it was pretty disgraceful. He is a high-end special operator for the US government. He was at the highest level. And so, you don't need to pull the top-secret card with someone like that, who understands the lay of the land. There's another way you can do it that's not gonna hurt people. So, the way she did it was kind of gnarly. It was much more like Doris. And so, as far as he's concerned, he's going to do what he's going to do. He certainly doesn't feel obliged to make sure he's got a blessing from her.

Will the serial killer storyline from earlier this season come back into play? We know Madison Gray is still out there.
O'Loughlin: I don't know. In true Five-0 style, we've just left a gigantic storyline on the shelf, which may or may not be picked up later. But there's a serial killer on the loose. I can't give away too much, but there's other things that they just sort of leave hanging there. I'm like, "Jesus, and then we all just go for drinks at the Hilton afterwards?" But yeah, I don't know. Wasn't Claire Forlani great?
Yes, that was my next question -- will we get to see any more of Alicia Brown this season?
O'Loughlin: I hope so. She's the best. We had a blast. We just laughed the whole time.
Hawaii Five-0 airs Fridays at 9/8c on CBS.
