* Chin Ho finally marrying Malia in "Alaheo Pauʻole". A WeddingDay is heartwarming anyway, but when you consider what Chin has been through and the reasons why he ended his first engagement to Malia, it's pretty clear that Chin [[EarnYourHappyEnding has earned his happy ending]].
* The ending of "Kahu". Can be a [=CMOA=] too.
* Steve shows up in his Navy dress blues in "Hana I Wa 'la" as a character witness for Danny [[spoiler:in his custody battle to keep Grace with him in Hawai'i.]] Even though his touching speech on why Danny is a great father is interrupted by a MysteryOfTheWeek phone call, it's still rather sweet of him. [[spoiler:It's even a deciding factor in Danny winning the custody case.]] The whole ordeal shows how far their friendship has come since Season 1.
* In "Ma'ema'e", Steve and Danny discover provocative pictures of a young girl in a suspect's home. They had been told earlier that the suspect was like a second father to the teenager. Danny's reaction is expected, but Steve proves to be just as infuriated as his partner about the possibility of anything like that happening to Grace.
-->'''Danny''': I do ''not'' think these were taken by a second father... If I found somebody taking pictures of Grace like this, I'd go to their house and I'd kill them.
-->'''Steve''': [[PapaWolf Yeah... me, too.]]
* The footlong rant Steve provokes out of Danny by throwing the word "classified" around when he resurfaces after his time away looking for Shelburn. He keeps smiling throughout the whole thing and keeps prodding his partner until he runs out of time. He clearly enjoys having that bickering back and makes sure they both have their share before he had to board that plane.
** Also, earlier in the episode when he calls Danny he hesitates for a moment because he know his partner will blow up on him, which he promptly did. Because he was [[AngerBornOfWorry worried rather than actually angry]].
** Danny using Steve's vocabulary on accident and Steve then saying he needs to get back right away. It's their subtle way of saying "I missed you". Aww!
* Just about anything with Max and Sabrina:
** Their first date is ruined when [[spoiler:she gets shot during a bank robbery]]. So, he makes a vending machine menu for her and they have their date [[spoiler:in the hospital while she recovers]].
*** Then you find out ''she kept that menu''.
** They also manage to make zombies cute:
--->'''Sabrina:''' Did you really think it was the ZombieApocalypse?
--->'''Max:''' No, but if it were, I would want you to kill me before I turned.
--->'''Sabrina:''' Nah, I'd make you bite me and we could [[EternalLove live forever and eat brains and have little zombie children]].
--->''(cue {{squee}}-worthy cuddle scene)''
* In the Season 4 finale, after Grover is forced into early retirement from HPD after saving his daughter. Steve and the rest of the team invite him to join Five-0.
* The 100th episode "Ina Paha" starts out like the {{Pilot}}, [[spoiler:except this time, Detective Danny Williams save Steve's father in time]]. It was nice to watch [[spoiler:until we learn it was [[AllJustADream only part of Steve's hallucination]].]]
** But it is also sweet because in Steve's mind [[spoiler: Danny could have saved his father and make Hesse talk.]] It shows how much he values his partner and how highly he thinks of him.
