Isa Drennan is played by Jane McCarry. She is the third resident of Jack and Victor's landing in Osprey Heights, and is Craiglang's local gossiper. She is aware of her reputation, confessing in "Gairden" that she is a "nosy b*stard" and will stop at nothing in her quest to find out the latest news. Isa works as a cleaner in Navid's shop and is shown to be a practising Roman Catholic. She has an estranged husband named Harry, who frequently had affairs with other women and stole money from her during their relationship. Also in the episode "Gairden," she mentions that she has a son named Colin. In "Dug" and "Hoaliday", she has a pretend relationship with Winston; although unrequited, Isa has a secret fancy for Winston but her obsession with gossip and tendency to be nosy often sabotages her chances with him, as he finds these qualities highly irritating. Isa is heavily involved with community projects and charities, attends dance classes and enjoys helping others. Winston maintains this is her way of keeping in touch with people to "keep on tap of everyone's business". Despite many people outwardly professing to be annoyed by Isa, she is still regarded as a vital member of the community, with the other pensioners immediately leaping to defend her if they feel she is being treated unjustly.
