Lily disliked Alicia's popularity and sound medical skills and Halfpenny believed that Lily was ``threatened'' by someone with both those skills. She began to resent Alicia and started expressing her resentment of her in front of their colleagues. Yu described Lily's actions as bullying, but believed that she bullied her because she was grieving for her father. Lily did not realise that _she_ was bullying Alicia and Yu explained that ``Lily says things in the heat of the moment and then regrets them, but she's too proud to own up or say sorry to Alicia.'' <sep>, Pronoun: she <sep>, A: Alicia <sep>, B: Lily
