Lynette Drinkwell is the adoptive mother of Scott Drinkwell. In March 2017, Lynette arrived in the village to visit Scott, and comfort him following the departure of his ex-boyfriend, John Paul McQueen.
When Scott had an argument with his aunt, Diane Hutchinson, in which he accused Diane of having an affair with his father, Lynette revealed that Scott's father had an affair with another woman, who was Scott's biological mother. Scott is devastated by the revelation and runs away. As Lynette prepared to leave the village, Scott returned and told Lynette that he wasn't upset as Lynette would always be his real mother - just shocked.
A few weeks later, Lynette and Scott met at The Hutch, with Scott wanting to learn more about his biological mother. Lynette gave Scott a letter from his biological mother, saying that she did not want Scott to find her as she did not want to be a mother to him. Scott discovered that Lynette wrote the letter and asked her to leave. Before leaving, Lynette revealed that the woman his father had an affair with was named Maggie.
In October 2021, Diane struggled with the family's move to The Dog in the Pond and decided to visit Lynette with her new baby Eva after the McQueen family's sabotage attempts caused an OCD flare-up. Diane visited Lynette again in October 2023.
