Arianna

Arianna is a neurotic, insecure, bossy, manipulative, sweet-natured, shy but mischievous and stubborn girl. She was very attached to her mother and feels partly responsible for her death - it was a car accident, her mother knew they were about to be hit and instead of unbuckling her seat belt and twisting out the way, she turned to make sure Arianna wouldn't be hurt. Two years later Jeff Walker (Arianna's father) remarried a woman who hated Arianna, and the feeling was mutual. Kelly-Ann sent Arianna to live in the family's rental house in Florida.
It was in Florida that Arianna got her first boyfriend, who cheated on her, ditched her, and then later, in a drunken rage, attacked her with a knife. Shocked, horrified, and bleeding from her side, she drove herself to the hospital where she was treated for her wound, emotional instability, and mental instability. She became friendly with one of the nurses who suggested she go for a cruise to get her mind off of it all. Arianna took her advice and the rest is, as they say, history.
As well as mental and emotional issues, Arianna's health isn't in tip top form either. She's had a condition since birth that is, as far as anyone knows, unique, and completely mystifies all the doctors she's seen. She takes medicine for it which treats the symptoms and keeps her alive. When she ran out after the wreck she did her best to replace it with herbal treatments, but they weren't strong enough and she nearly died.
Arianna was also well versed in herbal treatments, interested in it for awhile she read about it obsessively before becoming a midwife apprentice. She can be a bit overly sure of herself, leading to conflicts.
