Heart of Fire
- When Kathryn ends up in a lethal vision involving Sauron and the War of the Last Alliance, Smaug enters the vision to help her out of it. When she thinks him to be a part of the vision and refuses to listen to him, he's forced to swallow his pride and ask her to trust him, promising not to let Sauron have her. He then instructs her to imagine them in somewhere safe… and she imagines them inside the Lonely Mountain, much to his astonishment. After the vision's ended, he allows the grateful Kathryn to fall asleep in his coils, and he realizes he doesn't want to lose her.
- After killing the Knight of Gondor and witnessing her parents' death in a vision cause Kathryn to hate herself and her powers, Smaug — in his own brutal way — helps her to get over her guilt.
- When Smaug makes Kathryn leave Erebor, he gives her his own loosened scale and creates a magical link between them, showing how much he values her.
- Kathryn encounters several Good Samaritans after she leaves Erebor and Smaug behind.
- After making it through Mirkwood and falling unconscious from exhaustion, she wakes up to find herself taken care of by a human family journeying west. They don't figure out from her purple eyes that she's a Seer, so they treat her like any ordinary person until they part ways at Rivendell. One of them even helps her make a necklace out of Smaug's scale.
- The elves of Rivendell treat Kathryn kindly, with Elrond taking her in and teaching her to better control her powers. By the time she leaves, he has become fatherly towards her.
- After reaching Bree-land, Kathryn lives for a year with a Happily Married elderly couple who have no-one else to look after them. They pass away in each other's embrace, bequeathing their entire property to her.
- Bard being relieved to find his children unharmed during Smaug's attack and thanking Tauriel for protecting them.
- While their reunion happens during the assault on Lake-town and ends sadly, Kathryn and Smaug are truly happy to see each other after six decades of physical separation. He gives her back his scale which Thorin took from her, and it looks like she's able to convince him to stop the slaughter (even though he thinks he can come back later and finish what he started) and leave with her, promising to never leave him again. Maybe if Bard hadn't interfered…
Heart of Ashes
- When Smaug appears to help Kathryn through another vision at the end of the 8th chapter, she asks him not to leave her. He responds "Never".
- Kathryn spending time with the exhausted Smaug after she has saved him from death and helped him return back into a dragon. When she wonders what would have happened if they'd never met, Smaug says that he wouldn't have had "the only beautiful, honest and pure thing in his life" and they would have met each other anyhow.
- Queen Lalemwen, thankful for Kathryn's fabricated vision regarding the former's unborn child, promises the Seer that the latter won't be forever kept against her will in King Wilhelm's court.
- When Kathryn apologizes to Smaug for the grief her leaving Erebor caused him, he tells her that he sealed himself inside the mountain so that he wouldn't chase after her and take her back. She tells him that she doesn't want him to ever let her go again.
- The POV of the Haradrim woman Quithyra in the 15th chapter. She and her two brothers were sent to Vathvael by their father who had seen the dangers developing in Harad. When she passes her guard brother Zanros, they exchange secret smiles. She's also proud to serve as the physician of Queen Lalemwen whom she can tell is a good person, and that pride only grows when Lalemwen asserts herself before Beronor and Gregorse for the sake of her people's safety. It's nice to get examples of good Haradrim people who don't serve Sauron.…Quithyra raised her brows as she looked at the Queen in shock. Lalemwen had always been a gentle flower, but to discover her thorns now was most… inspiring. Quithyra couldn't keep the smile off of her face as she watched Lalemwen take her rightful place as a Queen.
- Smaug's thoughts reveal that while dragon males mostly just keep their hatchlings safe and provide them with a male example while letting the mothers do most of the nurturing, he has seen males who've been more than happy to watch their offspring while letting the mother hunt.
- Kathryn's happiness to reunite with Gandalf and Elrond in the 19th chapter.
- In the epilogue, Smaug, sorry for hurting Kathryn with his actions (this being the first time in his life he regrets anything), ends up finally telling her verbally that he loves her. She gives him the ultimatum to abandon his evil plans of revenge and conquest if he wants her love. He ends up giving that promise. Kathryn responds with Tears of Joy as she embraces his snout.
- A small one, but Smaug enjoys dozing in sunlight, something he has last done before conquering Erebor.
Heart of the Inferno
- Kathryn catching up with Elrond in the fourth chapter.
- Kathryn and Aragorn quickly start a friendship, with her offering him encouraging words both at their first meeting and in the dreams they share.
- The end of the 9th chapter: Kathryn has given birth to her twins Kolstros and Vervenia as well as survived the hard labour thanks to the recently resuscitated Gandalf the White. Smaug, having returned from fighting the Orcs of Dol Guldur and sensed Kathryn's near-death experience through their bond, is overjoyed by her survival and their twins' birth just as much as she and Gandalf are.
- Kathryn manages to make Smaug watch their twins while she rests. Much to her joy, she finds him holding them in his tail and lulling them.
- When Kolstros and Vervenia are first discovered in their dragon forms, they allow Galadriel to come close to them. The Lady of Lothlórien lets Vervenia sniff her fingers and Kolstros nip her long hair.
- When Kathryn implores her twins to bear with their imprisonment in Erebor, they solemnly vow to protect her as she protects them.
- When Kathryn and Faervel's intense argument leads to him admitting he missed her and how undeserving he thinks he is to travel to the Undying Lands, she puts aside her anger and tries to comfort her friend and reassure that staying to fight for the imperfect world is worth forgoing the joys of a more perfect world.
