Just seeing Klaus save a young slave boy in the 1800s from being whipped. And bonding with the boy as both being outsiders beaten for being different. The parental smile on his face as he names him Marcel is both uplifting as we see the hidden depths of humanity that Elijah and Caroline see in him, and somewhat bittersweet as, Klaus being Klaus, we know it won't end well.
Hayley handing over the daggers to Rebekah after the latter saved her. It's good to think that Rebekah might have a friend.
Marcel saving Davina's life; much as Klaus freed him from slavery, he sought to save a child he had never met.
Marcel first bringing Davina to the Attic that would become her home, he's just trying his best to make her feel safe checking to see what she likes to do. When she mentions art he offers to buy out a store just for her and maybe get her some drapes for her drafty, cobwebbed and dusty new home. The best part he seems to act like a big brother trying to comfort a girl recovering from a traumatic event, and clearly has no idea what he's doing but his best anyway for her.
What does Josh do when he finds out that Davina is on a mission to kill Klaus? Does he warn her that if she succeeds he will die? No , he tells her to give it all and don't hold back. Because her safety and freedom means more to him then his own life.
He later tells her that he loves her and so does Marcel
Marcel working with Elijah to protect Davina, they may not like each other very much but they are both willing to find common ground where she is involved.
Marcel rushes to save Rebekah from Klaus after he finds out that she and Marcel had used a witch to summon Mikael to New Orleans in 1919 to kill him. Klaus, of course, beats him readily and says he'll kill Marcel in front of Rebekah. Immediately, Rebekah tells Klaus that summoning Mikael to New Orleans was her idea. It's a testament to how much she loves Marcel. Prior to his attempt to rescue her, Rebekah was refusing to beg Klaus for mercy for herself, no matter what horrible fate he had for her.
1.15's flashback shows that Klaus had finally given his blessing for Rebekah and Marcel to be together. Too bad Mikael had come into town on that day...
Davina comes back to life after Celeste is killed for good. Marcel's face is like the sun coming up as he comforts her and says he won't let her be hurt again.
Elijah would rather risk true Death, and the wrath of his Father than turn against his brother.
Essential powerless Marcel still enlists Josh help in order to make sure that Davina is okay. Not because he needs a weapon because he still wants to look out for her.
Seeing that the witches have ordered for Davina to receive no gifts, Klaus takes it upon himself to give her not one, but two. First he pardons her best friend Josh, and then he gives her the spell to create a daylight ring for him.
Klaus turning Camille's uncle into a vampire so she could say goodbye.
All throughout the season, Hayley and pretty much everyone in the cast has been in doubt over how well/terrible a father Klaus will be. Hayley in particular has been wondering what's to become of her once she's given birth and has no other reason to stick around. Not only does Klaus tell her emphatically that their baby needs a mother, but he's been decorating the nursery. Complete with a crib, twinkling lights and his most recent paintings hung around. Given that it's Klaus, fatherhood can be the making or breaking of him. But right now, all signs are pointing to Klaus truly looking forward to being a parent together with Hayley.
The season finale is full of these.
Marcel giving Josh Klaus's blood to heal him, when Davina says "Please don't make me choose".
Later, he helps save the baby with the same weapon he was planning to use on Klaus.
In that same episode just about everytime someone holds the baby from Hayley, Marcel to Klaus.
Klaus thanking Marcel for saving his daughter's life and gives Marcel his blood so he can heal from the werewolf bite.
When they realize the baby will be in constant danger by living with them - the give her to Rebekah to take care of. Bonus heartwarming is that one of the reasons Rebekah previously wanted to become human was so she could have children of her own.
In that same scene, Klaus naming the baby
Hope...her name is Hope.
Elijah's gentle response to Klaus saying that his big brother's eternal quest for his redemption is like 'a man rolling a stone up an endless mountain.'
No mountain is endless, brother. Some are just steeper than others.
Elijah and Marcel's early relationship when Marcel was a boy in the Mikaelson home in the 1800s. Elijah is mentoring Marcel as he would a younger brother he has hopes for. Possibly a mirror to his lost relationship to Henrik. Marcel is eager to learn and hopes one day to be like the noble Mikaelson brother. Then Elijah pushes him away, because of Klaus' jealousy towards their bond. Marcel is bitter about his cold rejection years later, but he doesn't know the truth.
After their emotional dinner with Esther, Klaus is understandably upset that all his good memories of his mother from his childhood are tainted because the necklace she gave him suppressed his werewolf instincts and made him weaker. Elijah's response is to remind Klaus that not a single one of the enemies they've made in their existence - up to and including Mikael - have succeeded in killing him, because he is 'the most fierce' of all the Original vampires.
Despite technically being enemies Marcel, Gia and Josh decide to help Aiden, Hayley and Oliver to prevent innocent children being forced by Finn to commit murder. So that it not only triggers their Werewolf curse and provide Esther with further cannon fodder. But also scare the human faction in line . After they succeed Hayley, Marcel and Gia share a celebratory drink. While Marcel admits it may further escalate tensions between the Vampire and Wolves the group enjoy being able to do some good for once.
Josh and Aiden meeting in a bar. One is newly turned Vampire trying to adjust to his new life and alliances. The other is a Werewolf. torn by his loyalty to his pack and his love for his brother. But they both decide to try to forgot all that and instead pretend that they are two lonely guys out on a date.
Before leaving the bar where Klaus and Cami are drinking. Cami invites Klaus to dance, in order for him to remember his life is more then just darkness and rage. That he can find meaning in a a slow dance , a good friend. That in the end Klaus can't just have something to fight against. But he must find something to fight for.
While Elijah is recovering from a spell that forces him to relive all of the terrible things he did in the past, Klaus reminds him that they were forced into becoming vampires and that despite what they'd done, to Klaus's daughter they would be "knights in shining armor" who would protect her. He then admits, for once, that he needs Elijah. It was especially heartwarming after all he'd done to rescue Elijah and how harshly he'd dealt with his enemies in the previous few episodes.
The scenes with Rebekah and Hope in the playground before Esther's starlings find them both. It's clear that she loves her niece as if she were her own daughter.
Klaus and Hayley's reunion with Hope, hands-down and not to mention less then five minutes before as Elijah picked Hope up you can hear him call her "sweetheart."
Jackson's proposal to Hayley in 2.10
Klaus forgiving Elijah for Tatia's murder. To realize just how huge this moment is, Tatia may have been the only girl Klaus ever genuinely and truly loved. And for centuries, he and the rest of his siblings were led to believe that it was their mother who killed her. For Klaus - who seeks retribution for the slightest betrayal - to genuinely forgive Elijah for this shows just how far he's come.
Marcel's faith in his fellow Brotherhood in WW1. Ill equipped, low on rations he believes in his brother soldiers and they believe in him.
In a strange way, Klaus travelling thousands of miles to entice Marcel to return home, telling him to leave the food to fight amongst themselves.. Sure his technique needed work but in the end it seemed like a father trying to get his son to come home before he gets hurt.
Rebekah meets a new girl at the witch asylum, and decides to give her an apple she'd stolen from the pantry. Later, when the girl is caught with the apple and being abused by a Kindred witch, Rebekah immediately steps up and backhands the woman (though she pays for it later). She does this for a stranger she hasn't met before, out of the goodness of her heart. And it's because of that kindness that the girl - her older sister Freya - decides to help her escape.
Klaus willingly giving Kol the white oak stake to use as a dark object to stop Finn before he hurts Hope.
Finn's look of disbelief and joy when he meets Freya. After several episodes becoming more and more unhinged, it's nice to see him look so genuinely happy for once.
In a morbid way, Kol's death is actually this. When he died in The Vampire Diaries, it wasn't just violent and messy, he was completely alone and his last words to his siblings was to accuse them of plotting his death. This time around, he's surrounded by family and the girl he loves, and it's slow enough that he has time to say goodbye and reconcile with his siblings.
