Heartwarming / Haven

Season 1

• "Ball and Chain": Nathan's great with babies, which is both funny and cute. Also a Heartwarming in Hindsight moment, since neither of his fathers was very warm and fuzzy. He and Duke also have a Pet the Dog moment before it devolves into Don't You Dare Pity Me! on Duke's part.
• "Fur": Nathan reassuring the Troubled person of the week, who has been taxidermized by his mother that he still has his humanity, and uses some of the same language Jess gave him earlier in the episode to empathize with him.
• "Ain't No Sunshine": Nathan's reaction to Audrey's kiss.
  • And the entire episode "The Hand You're Dealt" (the pyro one), where Nathan is constantly finding excuses to touch Audrey—hand shakes, high fives, and so on. It would be creepy anywhere else, but in context its adorable since he can't feel anything but Audrey.
    • Also counts as something of a moment of funny since both in-universe and out, every one seems to notice his very odd behavior but they just don't comment.
• Taking in a stray cat.

Season 2

• "A Tale of Two Audreys:" The Ending of the 10 plagues Trouble with the happy baby and the shadow rabbit.
• "Fear and Loathing": Nathan giving up his ability to feel to allow Jackie to be rid of her much more cumbersome trouble.
  Nathan: (to Jackie) You have beautiful eyes.
• "Love Machine": Audrey II loses all her memories, and Audrey soothes her. Later, Audrey adds the wind chimes that Audrey II had suggested even though she earlier thought it was stupid.
  Audrey: Do you know who you are?
  Audrey II: Yes. I am... I... am... Oh, god, I...
  Audrey: It's okay. I'll tell you. Your name is Audrey Parker. You like—you like matinees in empty theaters. You hate runny eggs.
  Audrey II: What else?
  Audrey: You're an FBI agent. You became an FBI agent because you felt that if you could help people, help people in trouble, that you could—that you could connect.
  Audrey II: I'm sorry, I don't remember any of that.
  Audrey: That's okay. That's okay, because I do.
  Audrey II: How?
  Audrey: (tears flowing) You're my friend. We're like sisters.
  • Also in that episode The mechanic whose machines are coming to life to kill anyone who tries to get him to leave town, being forced to choose the machines due to the fact that they would kill the woman he loves if he didn't stay with them and let her move out of town alone.
• "Audrey Parker's Day Off": We find out Nathan and Audrey have come up with a system where Audrey checks the temperature of Nathan's coffee so he doesn't burn himself.
  • Audrey is getting worn down by the "Groundhog Day" Loop and seeing everyone she cares about die in succession, and Nathan provides her with calm reassurance.
• "Business As Usual":
  • Nathan giving Audrey Lucy's address, followed by Audrey promising she will come back and then finally kissing Nathan on the lips.
  • Lucy Ripley's reaction when Audrey arrives. From Lucy's point of view, she's meeting a beloved friend she has not seen in 27 years. Audrey's past incarnation asked her to wait until she came back. She waited.
• "Sins of the Fathers": Duke, when faced with the ghosts of his father and the Reverend telling him not to listen to Audrey, that she's a liar, quietly replies, "No. She's my friend."
• "Silent Night": Audrey getting Nathan and Duke the present they wanted.
  • The ending of "Silent Night" in general. It's one of very few episodes that ends on a positive note with the gang together and happy, and Audrey showing how happy she is to have found a home in Haven.

Season 3

• "301": Nathan and Audrey's reunion.
• "Over My Head":
  • Duke saving Daphne.
  • Jordan McKee explains that her Trouble causes anyone who touches her skin to feel unbearable pain and she has no control over it. Without hesitation, Nathan grabs her hand, his Feel No Pain Trouble making him immune. She practically cries Tears of Joy.
• "Double Jeopardy":
  • Duke says that while Audrey disappearing every 27 years is a bad thing, he's glad because it allowed him to meet her.
  • Audrey defying Lady Justice and Lynette by telling them that Duke is a true hero despite being a criminal.
• "Sarah":
  • In 1955, Nathan runs into a child version of his father, Garland Wuornos. The boy asks him if he can be a policeman when he grows up, and Nathan assures him that he can.
  • In the Bad Future, Audrey finds Garland Wuornos is alive. Garland believes her story, and is willing to help her try to get Haven back to normal, even though he is dead in the true timeline, just because in the original timeline, Nathan lived.
  • Sarah showing Stuart a picture of himself in the future, old and with a family, to help him get over his fear that he's going to die.
• In "Burned," any scene with Ginger and Duke is just so freaking adorable. Especially when he tells her about his little girl, from "Ball and Chain" whom most have forgotten about. The second time in particular since Ginger suggests he and Jean can come visit them. Crosses over into Tearjerker since Duke, knowing that he can never see Jean, can only look away with a pained look in his eye.
• In "Last Goodbyes," both Duke and Nathan's interrogations and memories of Audrey to prove they weren't the skinwalker were incredibly sweet and comforting. Both of their faces were just full of "Awww..."
  • The budding friendship between Audrey and Brady is a bright spot in an otherwise pretty bittersweet episode.
• "Reunion":
  • Audrey and Nathan dancing to "On Bended Knee" by Boyz II Men. Perfect.
  • Jeanine confessing to Robert, who used to be the class geek, that she had always loved him and was too shy to admit it, proving it by showing she remembers everything about him.

Season 4

• Season 4 in general: Duke and Jennifer's romance is so darn adorable. It brings out a very tender and soft side of Duke that's not seen in the rest of the series.
• Another one for the whole season: Aside from a few very understandable moments of frustration, Duke spends the whole season doing everything in his power to help and protect Nathan and Audrey, to the point of repeated risk to himself. Although there are other complications, it's heartwarming to see Duke finally being more honest about how much he cares about both of them.
• "Fallout": Nathan hugging Duke after Duke was missing for six months. Nathan has spent three seasons sparring with Duke, and was particularly hostile in the season preceding this episode, but for once there's not a hint of reserve or antagonism; he's just honestly, openly overjoyed that Duke is back.
• "Lay Me Down": Nathan tells Audrey, "I don't care who you are or what you are. I love you."
• "The Lighthouse": Gloria forgiving Duke for killing her son.

Season 5

• "See No Evil": Vickie uses her Trouble to entertain baby Aaron and make him stop crying.
• "Much Ado About Mara": When Dwight is finally convinced Audrey's personality still exists within Mara. He also admits that he always believed Audrey is a true hero.
• "Morbidity" onwards: Dwight and Charlotte's blossoming romance is really sweet to watch.
• "Reflection": Mara and Duke subvert this. They both either already have or later develop ulterior motives that make the scene awful to rewatch.
• "Chemistry": Played With in the case of Mara's motive and issues. When they're partially revealed, allowing her a shred of humanity, it almost achieve this effect because of just how inhuman she was before.
  • Charlotte's last words to Mara can be read as this or as a terrifying subversion.
  • The conversation Duke and Nathan share before the final Mara/Charlotte confrontation is very sweet. As is Duke's attempt to sacrifice himself to save everyone else is definitely that.
• "Just Passing Through":
  • Nathan meets his father in 1983, and 1983!Garland is open-mouthed amazed at how awesome his son turned out to be. (This is very late in season 5, so Nathan has almost completed his overall series arc.) It's a lovely moment of resolution for the Garland/Nathan relationship, as Nathan finally realizes that he wasn't a disappointment to his father—Garland had always known, ever since 1983, that his son would grow up to be someone he admired the hell out of. But there's a bittersweet aspect too: Garland seeing his son as an adult, everything he hoped he'd become, does obscure the fact that Garland was a shit father and his notion of raising Nathan to be "tough" was so misguided as to be actually counterproductive to Nathan's development.
• "Blind Spot:" While reinforcing the police precinct against Croatoan, who is after Audrey, Laverne's Trouble kicks in, causing her to literally embody the building. It's triggered by her desire to protect the people she cares about. One of the first things she does after this is basically shove Audrey into her office and lock the door. Why her office? When Duke goes to break down the window with a chair, Nathan tells him it won't work because the windows in Laverne's office are made of bullet-proof glass. She won't even let Nathan in until Audrey asks her to.
• "Forever":
  • Croatoan willingly enters the new barn, ending the Troubles once and for all, showing that he truly did love his daughter and would do anything for her.
  • Audrey goes with him to start it, then not long after returns to Haven in a new identity. Vince (now the barn's new caretaker) remarks that, though she couldn't have gone back as Audrey, she came back as someone else because she knew that she would fall in love with Nathan all over again.
  • The look on Nathan's face when he realizes it's not only a new Audrey that's returned, but also James, as a baby.
