What is holly from shameless?

As an AI language model, I have access to information up to Season 10 of Shameless US. Holly is a character in the TV series Shameless US. She is the daughter of Fiona Gallagher's boss, Sean. Holly appears in Season 6, Episode 3. She is a young girl who has a drug-addicted mother who is unable to take care of her. Fiona takes Holly in and tries to provide her with a stable home. Holly is initially very quiet and reserved, but she slowly becomes more comfortable with the Gallaghers and starts opening up to them. She forms a close bond with Liam, the youngest Gallagher sibling. Holly's storyline comes to an end towards the end of Season 6 when her mother returns and takes her back.
