Desperate to have children but with no stable partner in her life, Shortland Street clinic's Head of nursing
Carrie Burton (Lisa Crittenden) accepts sperm donations from nurse
Steve Mills (
Andrew Binns),
Guy Warner (
Craig Parker), Dr.
Hone Ropata (
Temuera Morrison) and Dr.
Chris Warner (
Michael Galvin); refusing to disclose whose sperm she used. She fell pregnant and married Steve's father
Declan Kennedy (Kevin J. Wilson). Carrie gave birth to triplets during good friend
Meredith Fleming's (Stephanie Wilkin) leaving party and named them, Frank,
Finbar, and
Sarah. Sarah was a surprise triplet, having been hidden behind her brothers in all of the previous scans. Sarah was the last to be born, but first to be named. The name came in tribute to Steve’s ex, and former Shortland Street nurse, Sarah Donnelly, who died at the end of 1992. Declan proved to be a useless father and ended up fleeing the country to escape criminal associates he had, leaving Steve to be a surrogate parent. It turned out Sarah had a hole in her heart and came close to death during surgery. Carrie decided to flee Ferndale after receiving threats from Declan's criminal past, taking her triplets with her and leaving Steve (who had decided the children were likely his) heart broken. Several months later Steve was devastated to realise Chris had discovered he was the father and had been visiting Carrie and the triplets in Australia. This caused a rivalry between the two that ultimately led to Steve driving off the road and dying in an explosion. In November 1995 Chris visited Carrie and the triplets so that he could introduce his father
Bruce (
Ken Blackburn) to them before he succumbed to terminal cancer. After having a one-night stand and not willing to pursue a relationship with a mysterious woman named "Sass",
TK Samuels (Benjamin Mitchell) was shocked to realise she was
Finn Connelly's (Lukas Whiting) triplet sister and long-lost daughter of Chris Warner. Sass quickly made an impression due to her direct and efficient manner, securing herself a position as Chris' executive assistant and making it clear she believed he had failed the triplets as a father. However the Warner family grew close, with Sass moving into the Warner household and getting to know half-brother
Harry (Reid Walker). Sass began a casual relationship with Hawks but was devastated when he abandoned her to go to Fiji. Shortly after Sass fell in love with Mayor of Ferndale, Mason and the two wed in a hurried ceremony. Sass began to worry about Mason's manipulative and controlling manner, and was overjoyed when Hawks returned to Ferndale. Soon it became apparent that Mason ran a major criminal organisation and was poisoning Sass, leading her to return to Hawks after he saved her and Mason was arrested. Sass and Hawk's relationship was tested when he cheated on her, but the two found an intimate and forgiving nature between them. Sass struggled with Chris' diagnosis of Leukemia and ultimately changed her surname to Warner to celebrate him. Following Hawk's disclosure of the death of his son, he again abandoned Sass to serve in Syria, and several weeks later Sass received the news he had died in an explosion. Mason escaped from jail and kidnapped Sass and his son
Jasper (Lachlan Forlong) on a boat, leading to Jasper dying from a head injury, and Sass murdering Mason with a harpoon gun. Sass escaped charges due to Mason's body deteriorating in the sea, leaving her a widow but away from his reign. She began to casually date
Curtis Hannah (Jayden Daniels) but whilst preparing for Finn's wedding, received news that Hawks was in fact alive after months in hiding. She decided to leave Ferndale to care for Hawks in Turkey following the loss of his leg, and bid farewell to Chris and her family. In 2019, however, Hawks mentioned that their relationship is effectively over because his phantom pain was so bad, that it affected their relationship, and she had been in a relationship with a French man. On the 2019 cliffhanger, she appeared via Skype to reveal that she has travelled to Hollywood to see celebrities. Sass made an appearance via video call after Chris was recovering from surgery in November 2021. Sass would reappear in person in 2023, working with her father and Monique Strutter (Courtney Louise) on finances to reopen Shortland Street hospital after it burnt down in a fire at the end of 2022. ==Reception==
