In To Ride a Rathorn, Timmon seduces Narsa, trying to make Jame jealous.Narsa is subsequently jealous of Jame because Timmon is more interested in Jame than her. Narsa and Timmon's dalliance doesn't last long, but Narsa is hurt and angry enough she tries to kill Jame by leaving Shade's snake Addy in Jame's bed, and then attacks her later in the Knorth quarters with a knife, though she's too upset to make a credible attempt at Jame's life.
That autumn, during Bound in Blood, Timmon takes Narsa back. Jame once asks Narsa for help in her attempts to keep Timmon reasoning that Narsa might help Timmon overcome the damage Pereden's example did to him, though Narsa just runs away. However, as Kendar females have no control of their fertility with Highborn men, she becomes pregnant, which would eventually disqualify her from randon training. During the Day of Misrule she attempts to order Jame to kill her, instead she is bitten by Addy, and proceeds to hang herself above Timmon's bed. Ironically, this does help Timmon free himself from Pereden's influence and example.
↑To Ride a Rathorn, "Chapter XII: Unsheathed", IV — "she ran into Timmon, arm in arm with a Kendar girl of his house. 'Have any good dreams last night?' asked Timmon. 'Because I didn't. At first. Then I remembered Narsa here, and the rest of the evening was quite jolly.' He toyed with a lock of the girl's dark hair as he spoke, glancing sidelong at Jame. It occurred to her that he was trying to make her jealous."
↑To Ride a Rathorn, "Chapter XX: The Bear Pit", II — "an Ardeth girl brushed past them on the way down the stairs, ramming her elbow into Jame's sore ribs […] 'Narsa!' he shouted after the descending Kendar. 'Stop that!' […] 'Still after you, is she?' Timmon looked exasperated. 'I keep telling her that it's over. Why won't she believe me?' 'You, my boy, have been a bit too free with your glamour,' "

↑Bound in Blood, "Chapter V: Fractures", I — "As the easiest course, he had again taken Narsa into his bed. Jame worried about that. Surely the Kendar knew that he was only using her, but he had woven his charms so well that she probably didn’t care. Whenever Jame saw her she looked happy, though with a certain uneasy, feverish gleam in her eyes."
↑Bound in Blood, "Chapter VII: Rude Walls", II — " 'This was to be our special day. We were supposed to spend it together. […] You claim that you don’t want him. […] What good would that do anyway? He prefers you. He always has. And now that I’m p… p… p…' […] 'Please, Narsa. Put away that knife and let’s talk sensibly.' 'I don’t need sense. […] My honor is already dead. Should I give the world another bastard? The Ardeth are jealous of their oh-so-pure blood, […] Timmon should have thought about that' […] Then the Kendar collapsed into the Highborn’s arms sobbing. […] Narsa shuddered in her grip, so strong, so alive, so desperate."
↑Honor's Paradox, "Chapter VIII: New Year's Eve", I — " 'Narsa. Hanging over my bed. Still warm.' […] Suicide without even the dignity of the White Knife, solitary, desperate, and unexplained, […] '…and her leg, […] Dangling there, all black and swollen.' […] 'Addy! She was underfoot. If Narsa trod on her… […] It must have been hideously painful,' "
↑Honor's Paradox, "Chapter VIII: New Year's Eve", II — " ' Tentir has made me question most of what I used to believe. So you tell me: am I responsible for Narsa’s death?' […] 'Narsa was carrying your child.' Timmon’s face bleached behind its freckles. 'Oh,' he said. 'Then I am responsible. I had better go and tend to the body.' "
