- Angst? What Angst?: As soon as Sibeal finds a way to bring both halves of herself together, the world is right again.
- Vows? What vows?
- The Determinator: Liadan. Despite constantly being told by the Fair Folk and Conor that she cannot have both her lover and her son in her life, she never listens to them and makes her own choices which eventually lead her to a future with both Bran and Johnny in it.
- Also Gull, during the escape from Sidhe Dubh in Son of the Shadows.
- Sorcha, due to her unwillingness to give up her quest to break her brothers' curse, even when threatened with death.
- Clodagh can be counted as well as she refuses to give up on Cathal when he is trapped in the Otherworld and risks her life to rescue him from Mac Dara.
- Draco in Leather Pants: Everyone really likes Knut when hes pulled from the shipwreck. Hes helpful, concerned about everyones welfare and even takes part in the fighting challenges on the island. Its all a façade.
- Fridge Brilliance: The original Sevenwaters family and the Sevenwaters family in the later books are like mirror images to one another. For example:
- Niamh and Colum had six sons and one daughter/ Sean and Aisling had six daughters and one son.
- Niamh died giving birth to Sorcha/ Aisling almost died giving birth to Finbar.
- Niamh always longed for a daughter/ Aisling always longed for a son.
- Sorcha was beloved of her brothers and raised by them/ Finbar was lonely and neglected, and barely knew any of his sisters as they were already grown up and married.
- Idiot Plot: In Son of the Shadows. The entire conflict concerning Niamh and Ciaran's affair and Fionn's abuse of Niamh could have been averted if Conor, Liam and the men had told Ciaran and Niamh from the start that their love was forbidden because Ciaran was her half-uncle. Liadan calls Conor out on this when she realises it.
- Jerkass Woobie: Clodagh remarks that Cathal is the rudest man shes ever laid eyes on. Even after Clodagh rescues him from the Otherworld, he maintains some of his jerkass qualities. But its clear hes softened after his journey, particularly where Clodagh is concerned. He becomes a Bruiser with a Soft Center.
- Magnificent Bastard: Mac Dara. To an unimaginable degree.
- Moral Event Horizon: Almost all the villains have one.
- Oonagh's comes when she turns Sorcha's brothers into swans.
- Eamonn the Second causes the death of Liam, who is like a father to him, and kidnaps and tortures Bran and Gull.
- Mac Dara crosses it when he kills Aidan, Cathal's best friend, and burns Glencarnagh to the ground.
- Richard of Northwoods crosses it when he orders his men to kill Sorcha when she is out gathering starwort. They end up killing John instead, who was guarding Sorcha.
- Official Couple: Sorcha/Red, Liadan/Bran, Ciaran/Niamh, Fainne/Darragh, Clodagh/Cathal, Sibeal/Felix, Aisha/Conri, Muirrin/Evan... the list is endless.
- Stoic Woobie: Ciaran. Also Sorcha in Daughter of the Forest.
- Useless Protagonist: Fans seem to be divided about Felix. Half of them think that hes absolutely useless and half say that he gets better towards the end.
- Its probably because he doesnt do much physically like the other male protagonists have in past books. He uses his voice, whether its telling a story or singing to keep spirits up or debating important matters, because thats where his strength lies. He still saves people, just not with brute force.
