Kensit and Roberts reprised their roles for a single episode in 2019 to coincide with the show's twentieth anniversary. Writers used the unresolved tension between the characters to develop "a playfulness and a real strength and humour" in their portrayal. Kensit observed that the "bitchiness" between the characters is "heightened" in Faye's return, which she liked as she felt it added to the episode. Faye returns in need of a heart transplant and has to be admitted to Holby City Hospital when a rainstorm hits. Kensit said that Faye wants to avoid Jac and the hospital, but it becomes "the only option". On the moment Jac sees Faye again, Marcel commented, "Jac's feisty spirit certainly comes tumbling out!" The pair do not want Jac to perform surgery on Faye, but understand that she is the best in her field, which would give Faye the best chance of survival. When Joseph returns, it emerges that he and Faye are back together. He asks Jac to perform the operation and she agrees. Roberts told Wilson (What's on TV) that Joseph and Jac have "enormous underlying respect for each other as professionals", which means he can recognise her excellence. Marcel explained that Jac feels that she has to agree because Joseph asks. She added that Jac now "can hold that over Faye for a very long time".
