Yvonne first appears when Dot and Shirley Carter text her from her son Charlie's mobile phone and arrange to meet at Dot's house. They meet, and Yvonne and Dot immediately clash, but later get on. She confirms that Charlie is her and Dot's son Nick's son, after Dot believed that Charlie was lying to her about his identity. When Charlie and Yvonne leave, it is clear that something is suspicious as Charlie asks whether Dot believed what Yvonne has said. They also imply that Yvonne has been hurt by a member of Dot's family.
