Matthew’s mother and a trained nurse, Isobel is an opinionated and knowledgeable character who feels no great loyalty to propriety and aristocratic tradition. She’s often written as the foil to the family, especially the Dowager Countess, and will express a more modern perspective on whatever plot trouble is around. In some of my episode breakdowns I complain about this. She feels forced to do things against her nature so that other characters can react and advance a conflict.
If I look past what I consider to be unfair writing for her, who is Isobel? She’s competent and, let’s be fair, bossy. She wants her way with the doctor and the hospital management. She’s very respectful of Matthew’s independence. Whoever he loves, Isobel will love. However involved he wants to be in the Downton estate, Isobel is supportive.
The key to her, as I mentioned under the Dowager Countess’ page, is the friendship between these women. At first, they’re adversarial. Some of that is the writers making them represent different perspectives for the audience. Underneath, though, their antagonism is due to them both being strong leaders. It’s natural they would clash. When Violet becomes ill and Isobel is the one trained and willing to nurse her through it, their friendship advances. Isobel is a genuinely giving person. Although she often disagrees with the Dowager, she will still befriend her.
I’m leaning toward a Four. Envy does eat at her, although Isobel isn’t consumed by it. She is absolutely Heart, needing to connect with family and community. I would say Two, but she’s too confrontational. When she feels she’s right, she’ll fight for it. When Lord Merton’s children are cruel to her, though, she retreats. Their feelings get priority. Isobel doesn’t have the black and white standards of a Six. Her heart rules her reactions, and she is a woman with passion. The world can wound her, but she rallies. Very Four.
