Mai Ka Wa Kahiko (episode)

Mai Ka Wa Kahiko (Out Of The Past) is the 15th episode of the second season in the remake version of Hawaii Five-0.

Synopsis
A crooked cop who is seeking revenge against Danny decides to visit the island, putting Danny and his family in jeopardy.

Plot
An Air Marshal and a friend of Detective Danny Williams is found murdered in a bathroom on a plane, prompting the Hawaii Five-0 Task Force to investigate.

As the investigation progresses, the team discover that the prisoner the victim was escorting, "Rick Maguire", is an alias as the real "Rick Maguire" died two years previously.

It's soon discovered that the main suspect in Rick Peterson, Danny's ex-partner from his days as a cop in New Jersey. After being found guilty of corruption, during a trial that Danny also testified in, Peterson was jailed for ten years and ended up losing everything, including his wife and son.

Now consumed by revenge, Peterson has come to Hawaii to get back at Danny.

When Grace is kidnapped by Peterson posing as an officer of the Honolulu Police Department, Danny goes off the grid to comply with Peterson's demands. Danny is by himself as Peterson has also cloned Danny's phone, essentially gaining access to the contacts on Danny's phone, which include members of the HPD and H50.

Peterson and Danny then meet, with Peterson telling Danny to kill Stan Edwards, the current husband of Danny's ex Rachel so that Danny himself would end up going to jail for murder and ultimately end up losing Grace forever.

As Danny and Stan meet, the rest of H50, having discovered that Peterson was taking photos of Grace discover Peterson's intentions and race to stop the plan from going ahead.

Lieutenant Commander Steve McGarrett arrives to stop Danny, only for Danny to shoot Stan. As Steve races to the scene, he discovers that Danny simply shot Stan in the shoulder with 2 in the grass, wounding him so that he could trick Peterson.

Peterson is later apprehended by Lieutenant Chin Ho Kelly and Officer Kono Kalakaua.

With Kono and Chin, Danny confronts Peterson, demanding that Peterson reveal where Grace is, but when Peterson refuses, Danny responds by shooting Peterson in the right kneecap which leaves Kono horrified and stunned, but Chin appears to be absolutely OK with it.

As Peterson lies on the ground, wounded, Danny tells him to give up the location or else he will shoot Peterson in the head.

Peterson eventually relents and reveals that Grace is being held in a storage container.

Steve and Danny race to the container and eventually find Grace, with Danny, Rachel, and Grace having an emotional reunion as Steve, Chin and Kono look on.

Lori Weston: Nature's Stairmaster?

Steve McGarrett: Okay, listen, if you don't think you can hack it, you need to tell me now, all right? 'Cause I don't want to get halfway up and have to carry you back down.

Lori Weston: Listen... I was shot-put champion three years in a row in high school.

Steve McGarrett: Well, congratulations. You know how to throw little balls around; that's great.

Rick Peterson: You know, I'm surprised. I thought Manhattan was the only island you'd ever set foot on.

Danny Williams: Listen to me, listen to me, you son of a bitch. Whoever this is, if you touch my daughter, you lay a finger on her, I swear to God I'll kill you, you hear me?

Danny Williams: Okay.

Rick Peterson: with a disposable phone taped underneath. You're gonna wait for my phone call.

Danny Williams: Okay. Uh I'll do what you say. Just please, please don't hurt my daughter, Rick. I'll do anything. Just please, please don't hurt her.

Rick Peterson: Oh, D. Whatever happens to Grace, that's.. It's all.. it's all on you, buddy. You act like a smart guy, you don't do what I tell you to do and then sweet, beautiful little Gracie dies. Now, do we understand each other?

Danny Williams: Yes. Yes. I understand perfectly.
