Elijah bargaining the cure for a werewolf bite for Jane-Anne's body.
Earlier in the same episode, Elijah's heart-to-heart with his little brother, Klaus. The speech he gave plus the beat-down was quite the awesome combo. Even if Klaus was beating him up, too. It's these scenes that make Klaus daggering his brother again all the more heartwrenching.
In the episode "House of the Rising Son", Davina throws an Original Vampire out the window with only her mind.
But not before knocking out Rebekah, said Original Vampire, and erasing her memory of the location of the Church she was in.
Later on, she then boils Klaus' blood from the inside. The only reason Klaus made it out of the church alive was because he had the foresight to bring a hostage with him: Davina's childhood friend Tim.
Klaus pulls a truly masterful Batman Gambit in the third episode, manipulating basically the entire rest of the cast to his own ends. It ends poorly for everyone but Klaus, naturally.
Marcel's Big Damn Heroes moment, where he swooped in to stop the Harvest Ritual Sowing and saved Davina's life.
Elijah, killing Agnes. "No one hurts my family. No one."
Even though Marcel's plans against Klaus has failed and he lost his kingdom towards him he manages to have one final moment of defiance by giving Klaus "The Reason You Suck" Speech by explaining how meaningless Klaus's victory is.
Which speaks volumes given how Klaus has pretty much drove his family away, caused Hayley to hate him, and even destroyed any chance at being a father to his unborn child.
Before the above, Klaus versus something on the order of fifty to a hundred vampires at once. He just lets them beat on him for a while, and it actually looks like they might have a chance, Rebekah even stepping forward as if she's about to add a few hits herself. And then Klaus looks up, his eyes go yellow and the veins appear, and he growls deep in his throat. And proceeds to completely annihilate everybody in his path until Marcel surrenders. Rebekah's look of horror is what ultimately sells it. Counting up the casualties, approximately two dozen vampires were permanently killed in that fight.
In a subsequent episode, Elijah stops a vampire hunting party out to kill werewolves by very calmly pointing out that there were considerably more of them when they tangled with his little brother Niklaus. The vampires back down immediately.
Davina using her telekinesis to simultaneously break four witches necks at the same time.
Davina: ( Dismissively) That's enough out of you. Then snaps his neck with a gesture
She didn't just make Klaus beg in front of her. She was about to force him to turn into a werewolf. This is only topped off by her making Elijah choke on a thousand years' of blood. And before Rebekah appears to save him, she was going to boil Marcel in bronze.
Klaus backup plan was a dark one, reminding everyone why he is MagnificentBastard that is more then brute strength.
Even Marcel has a backup plan just in case Klaus enacts his, in effect saving Davina from a lethal poison not even Vampire Blood could heal. Then again he had a hell of a teacher..
Celeste has been playing a long game since before the series started, and by episode 13, the fruits of her labour sees Sophie-Anne dead, Klaus and Rebekah MIA, Hayley almost killed and Elijah severely emotionally compromised by her reappearance and the subsequent fall-out on his family.
It soon becomes clear that Celeste's plan is not just revenge. She wants to tear the bond between the Mikaelsons asunder, and so far she seems to be succeeding.
Hayley knocking out Celeste and capturing her was pretty awesome, considering the trouble Celeste made for the Originals.
Rebekah - weak with werewolf venom, delirious and scared out of her mind - is cornered by a vengeful Klaus after he learns that she and Marcel had summoned their father Mikael to New Orleans to kill him. And what does she do? She picks up a rusty iron and charges at him. It isn't effective, but Rebekah will be damned before she goes down fighting.
Elijah's Big Damn Heroes moment, when he stabs Klaus with Papa Tunde's knife before he can do the same to Rebekah. Subverted in that this action might have come at the cost of whatever trust Klaus still had in his big brother.
In his mission to resurrect Davina, Marcel gets one when he takes out an Elder Witch using surprise tactics, and rips off her head one handed...
In the flashback of 1.15, we have Elijah standing up to Mikael and calling him 'a fool without equal' for even thinking that he would kill his own brother. Considering that Mikael has the in-universe nickname of The Destroyer, that took serious balls.
Cami deserves a mention for not only staying with Klaus - when there was a good chance she would be the victim of his fury - but she tries to get him to stop going off to kill Rebekah with his white oak stake.
Elijah outsmarting Celeste by enlisting Monique's help to seal her spirit back in her original body after she 'kills' herself, thereby cutting her off from her source of immortality.
Elijah is really shaping up to be the Noble Badass of The Originals this season.
Hayley while briefly dead thanks to Monique's voodoo, finds herself threatened by Mikael. What does she do when faced with a thousand year-old vampire so dreaded that even Klaus is terrified of him? She beats him down for threatening her baby.
Hayley while staking Mikael: My daughter has one advantage that [Klaus] never had. She will never know you.
The revelation that Francesca Correa, defacto leader of the human faction, and her family are descendants of the Guererra werewolf line supposedly wiped out by Marcel. She'd struck a deal with Genevieve to take the black kyanite stones for herself, and with everyone nice and divided from Marcel and Klaus' battle, she and her brothers proceed to poison every vampire in the Quarter.
And before that, we have Elijah vs. Marcel's vampire army. This isn't like the last time: apparently, every vampire in the Quarter had sided with Marcel. Before Francesca comes in, Elijah had taken out nearly half of them. And he wasn't even breaking a sweat.
Keep in mind that before the reveal The werewolves were pretty much the ones that gets stomped by the vampires but this is the one episode where they not only get a chance to shine but to actually make the vampires become the ones being hunted in the process.
Davina bringing back Mikael, but not without making it so she could control him. The girl seems to have learned well from Marcel.
To get an idea of how awesome the above is: Mikael has the in-universe nickname of The Destroyer. He's the one being that Klaus - arguably the most powerful living supernatural creature in the world - is afraid of. And what does this sixteen-year old witch tell him to do? Kneel.
From that same episode, the fight between Elijah, Klaus and Hayley against the witches attempting to sacrifice Hope. Keep in mind the witches were backed up by the Ancestors. Mama Bear and Papa Wolf at it's finest.
To put the cherry on top, there's Marcel's Big Damn Heroes moment where he killsMonique with the Devil's Star - a weapon he intended to use on Klaus
Davina's awesome extends into Season 2. Not only does she manage to subdue four werewolves at once, but she also manages to cloak the white oak stake with a spell that Esther can't break.
Not to mention that she still has Mikael under her control and is apparently close to figuring out how to break Klaus' sire-line so Marcel and the other vampires don't die once he gets killed.
Klaus, Elijah, Hayley, Camille and Marcel working together to take out the Guerrera wolves and most of their allies in the course of a single night.
It begins with Camille giving false information to the wolves so they go looking for the white oak stake in a warehouse with functioning water sprinklers...that Marcel kindly filled with wolfsbane.
Then it escalates with Hayley and Klaus dispatching the wolves sent to the Mikaelson estate to kill Klaus. This all occurred during the full moon, where Klaus is weakened through the black kyanite stones.
And finally, as Elijah corners Francesca and her brothers in their home, he reveals to them that he used his influence on the city council to declare their home a heritage foundation. Meaning it's technically owned by the public, and thus anyone can enter without invitation....Francesca only gets away because Elijah wanted Hayley to have the pleasure of killing her herself.
Even before the final fight, the Mikaelson brothers had destroyed Francesca mentally...by doing nothing. A straight up war she could handle, and even expected. Instead they did nothing for months, staying behind locked doors and letting the formerly arrogant Alpha wait in fear for a retribution that never came. All her frantic energy and werewolf aggression turned inward, making her paranoid and restless. They'd already won half the battle without ever making a move. Even their mother was impressed.
Davina summoning Mikael to tear apart a group of werewolves who had been threatening her under Esther's orders. He kills them with ease and almost kills Elijah in the process.
Esther in 2.03, moving constantly one step ahead of her two sons and showing them all which parent Klaus got his Magnificent Bastard genes from.
Klaus facing Mikael again and stabbing him with Papa Tunde's knife. Unlike when Klaus faced Esther and was reduced to an emotional wreck, he barely flinches from facing down his horribly abusive father and manages to get the best of him. It's a shame that Mikael was able to pull the knife out.... Klaus also gets bonus points for not killing Mikael and being better than that, though some would argue that leaving Mikael in eternal agony would not be necessarily better...
The fight with Mikael in The Red Door, this time it's him fighting not just Klaus, but Marcel, Hayley, Davina and Kaleb/Kol. Long story short, Mikael gets his ass handed to him.
Camille even calls Mikael out on his vendetta towards Klaus as being pointless, and while it results in his Villainous Breakdown that nearly gets her killed, it's still pretty awesome.
The icing on the cake is that while Mikael mocks Klaus for needing 'women and children' to fight his battles, it's the first time onscreen - and in a thousand years - that Mikael runs from a confrontation with Klaus.
Jackson's Big Damn Heroes moment where he shows up just in time to save Hayley from being killed.
Rebekah who sees that something is seriously wrong with Elijah after discovering the bodies of the diner customers he needlessly massacred to ensure no-one knew of Hope's whereabouts. She keeps her cool long enough to catch him off-guard and break his neck, rather than take the chance that he would snap and hurt the baby.
The mid-season finale, in which Klaus and Rebekah work together to get Esther to ingest vampire blood unknowingly so they can kill her. She wakes up in transition, stripped of her powers and her ability to jump into bodies, and is given a choice: either drink the blood bag Klaus left for her and become a vampire (aka everything she has hated for a thousand years), or die permanently. As Klaus bitterly notes, it's still more of a choice than she ever gave him and his siblings.
Rebekah showing that even in a mortal body, she is still a badass of her own, owning a group of witches with only her hands and feet.
Finn's "The Reason You Suck" Speech to his mother after discovering she became a vampire when presented with the choice, rather than dying with her much-vaunted morals intact.
