He ke’u na ka ‘alae a Hina
Danny protects a coma patient showing signs of waking who was the key witness from his last HPD case before he met Steve and joined Five-0.
Present day: While Danny and Steve are fixing up Charlie's room Danny's old boss from HPD, Captain Tanaka, visits Danny and tells him that a witness from an old case who was presumed dead has appeared again. Tanaka saw a news report fearuring "John Doe", a coma patient of seven years who will probably wake up soon, and he thinks this is their witness.
7 years ago: Danny arrives at a crime scene and is greeted by his then-partner Meka. Captain Tanaka is already on scene and demands that the case is closed quickly as the Governor's chief of staff lives in the neighbourhood. Danny notices a man who is loitering at the crime scene and confronts him. The man identifies himself as Makino and tells Danny that he lives close by but that he wasn't around last night. Danny suspects Makino might have seen the murder and gives him his card.
Present day: Tanaka and Danny are at the hospital and Danny confirms that "John Doe" is indeed Makino. They decide to take him in protective custody but before they can do so the hospital's alarm is set off: The hospital is now on lockdown due to a security breach. Danny and Tanaka suspects this is not a coincidence and that someone in the hospital will try to kill Makino. Danny calls Steve for backup.
7 years ago: Danny is fighting with Rachel on the phone when another cop tells him that he's got a call from a man he gave his card to on the crime scene that morning.
Present day: A nurse comes into Makino's room and Danny tells her they have to move him. The nurse tells him she's not authorized to move him though she can get somebody who is but first she wants to check in with Makimo. When Danny gets suspicous because she knows Makino's name she attacks him. Danny manages to get the upper hand and injects her with the syringe she intended for Makino. Then Tanaka and a real nurse called Jenny come in.
7 years ago: Danny knocks at Makino's door and notices it is busted open. When he comes in the flat is empty but there are signs of a possible struggle.
Present day: When Tanaka finds a burner phone on the fake nurse Danny sends the numbers that have called this phone as well as a photo of the dead hitwoman to Jerry. When an incoming text asks if the hit was successfull Danny texts back, however the senders are wary and call, so Danny tells the nurse to pick up and say that everything is alright. When this doesn't work they prepare to leave the hospital with Makino immediately.
7 years ago: Danny argues with Tanaka who wants to take him off the case. Danny argues that he has leads. He suspects that Makino was stealing copper at the crime scene, saw the murder and has now been taken. Tanaka, however, is not convinced and questions why Danny hasn't kept better tabs on Makino if he is a supposed eye witness and how he lost him after Makino called him. Danny tells him that when he picked up the phone Makino was already gone and after tracing the call only found the empty motel room. Tanaka argues that if Danny is right Makini is already dead and takes him off the case. He instead assigns Danny to the case of John McGarret.
Present day: Danny calls Steve to tell him that they plan to move Makini to the next precinct where they should meet up. Meanwhile at HQ Jerry, Chin, Kono and Lou identify the fake nurse as a contract killer. One of the numbers on her phone matches to Dario Mendez, the current head of the Ochoa cartell who could lose a lot if Makino were to testify. They decide to go to Mendez to get gim to call back the head squad.
7 years ago: Meka tells Danny that it is not his fault he lost Makino and that there was nothing he could have done.
Present day: The hitmen are closing in on Danny, Takena, Jenny and Makino. Danny manages to kill two of them in the hospital but several more are following them and shooting at them. They temporarily give their pursuers the slip but with the ambulance damaged they know they won't make it so they hide out in a secluded house. Danny calls Steve but doesn't know the address of the house they are staying so Jerry tries to triangulate his position but due to the bad signal can give Steve only a half mile radius of Danny's location. Meanhwile Chin, Kono and Lou have arrived at Dario Mendez' house and confront him.
Back at the house Tanaka and Danny begin to argue while searching the house for guns. Tanaka thinks Danny blames him for this situation as he took Danny off the case. He tries to apologize and says that taking Danny off the case was not about him personally and that losing Makino was not his fault. Danny doesn't want to hear Tanaka's apology and insists that this is his fault and that he could have prevented this: Seven years ago, when Makino called, he didn't pick up the phone in time because he was busy fighting with Rachel. Tanaka tells him he shouldn't blame himself and that he is a good cop. Danny reacts with disbelief since Tanaka never wanted him around at the first place. Tanaka claims this had nothing to do with Danny's abilities as a cop; there were many officers in line to make detective but Tanaka was pressured to hire Danny, who was from the mainland and didn't get along with anybody. He asserts he didn't come to Danny because of his connection to the case but because he thinks Danny is a good cop. By now the hitmen have found them. Danny and Tanaka fend them off until Steve arrives who drives his car into the house, killing the last two hitmen.
Afterwards Danny apologizes to the still unconscious Makino for not being there to pick up the phone. He then tells him about his family and thanks Makino as he wouldn't have met them if it wasn't for Makino.
