Appearance
Sienna has brown eyes, long brown braided hair and tanned skin. Her casual outfit consists of a denim jacket over a dark red dress combined with a necklace. She is described to be petite.

Personality
She says she can't stand inconsiderate people and if you tell her that you don't want her to get in trouble for you, she says she can't help it because that's who she is. She appears to be the cook/baker of your group of friends as she bakes cookies when she can't sleep and makes breakfast for everyone once you all rent a place together. She tends to hide her feelings behind a smile. She has wanted to help people all her life, to the point where she focused on their problems instead of her own.

Wayne
In Chapter 2, she mentions she had been living with her boyfriend, Wayne, but it was not an ideal living situation since he lives far away from the hospital, so she doesn't get enough sleep. When you all find a place to rent together, he hasn't come to visit the couple times he has been invited. If you point out that Sienna has just as demanding and busy a job as he does, she appears crestfallen that she has to defend him. In Chapter 6, he finally comes to meet you at the housewarming party and rubs all of you the wrong way. If you decide to talk to Sienna about him, she brushes it off, not wanting to talk about it. In Chapter 12, she tells you that she tried to talk to him about her troubles at work, but that he doesn't understand why she wanted to become a doctor in the first place. In Chapter 14, after he is angry that she stood him up for dinner (dismissing her blood covered scrubs and reasons for being busy due to the subway derailment), you can help Sienna dump Wayne or tell her to deal with him later. If she doesn't leave him in Chapter 14, it's revealed in the final chapter of Book 1 that he tracked her phone. She then takes his phone and throws it into the back of a truck passing by, telling him that they are over.

Your Character
You first meet her when she "rescues" you from Dr. Ramsey's scolding. After your first shift at the hospital, you and the other interns head to a bar to relax. It is her idea for all of you to move in together to get a better place than the individual rooms you each rent; you all agree, find a place, and move in together. In Chapter 5, you have the option to kiss her if you are wearing the premium outfit. After she told you about possibly resigning, you, Danny and your friends take her to an animal shelter to cheer her up in Chapter 12. You intentionally didn't invite Wayne.

Danny
In Chapter 6, at your housewarming party, Sienna and Danny, a nurse at your hospital, bond over The Secret of Ninradell. The next morning, you find them fallen asleep on the couch. In Chapter 7, when your friends are trying to help you figure out who Patient X is, she mentions asking Danny about the hospital patients and not finding any information that would help. Your friends tease her about being on a first name basis with Danny. In Chapter 12, he arranges with his cousin, Kima, a trip to the animal shelter to cheer up Sienna. In the final chapter of Book 1, if you helped her break earlier with her boyfriend in a Diamond scene, she'd tell You that she has a "small crush" while looking at him. She is distraught when Danny dies in Book 2, Chapter 11.

Mitch Keller
In her second year at Edenbrook, she becomes the resident in charge of intern Mitch Keller. She is excited, but he laughs at her and questions whether Sienna is indeed his resident. The moment passes when Sienna tells him that she is very thrilled to meet him.

In Chapter 5, Sienna tells you and your friends that Mitch keeps telling her how lucky he is that she is his resident, which means a lot to her. In Chapter 7, Sienna tells you and Jackie that one of his patients had died and she had to tell the family. When asked why he didn't tell the family himself, Sienna says that he said 'he wanted to see how the pros did it' and that he's very eager to learn from her. If you try to voice your concern about him, she dismisses your worries. In Chapter 13, she finally comes to the realization herself - that he is lazy and disrespectful. She yells at him that respect must be earned not asked for. She also realizes that she has let him get away with it for far too long, and Marlene encourages her when she gives him a piece of her mind. You can also encourage her or calm her down.

In Chapter 14, fellow physicians begin to make fun of him, calling him "Puddle" in reference to Sienna's earlier outburst. You can tell Sienna that it's what he deserves or that the name-calling is going overboard, but she tells you that if he didn't want the reputation of being lazy, he should have put the work in that was required. Later though, she tells you that he quit his job. In Chapter 16, she feels a little guilty that he left.
