Episode Two - "Out Of Time" Edit
She is only seen on two photographs in Kate's room. When Kate thinks that nobody cares about her at the dormitory rooftop, Max Caulfield may mention her sisters and Kate will mention Lynn Marsh's name, age, and smile. Max's dialogue when referring to her differs depending on if she saw the photographs. If she saw it, Max will say, "I saw that cute photo of you with your sisters in your room this morning. I can see how much your little sister loves you by her smile." If she didn't see the photo, Max will say, "You told me about your sisters, especially the youngest one... What's her name?"
The name "Lynn" appears on one of the folders in the Dark Room. It is not clear whether this refers to Kate's sister and she could possibly be a victim. Due to Lynn's age and unlikelihood of her being around Blackwell and the other victims, it is improbable that Kate's sister is the same victim in the portfolio. It is however possible that Mark Jefferson knows of her sister and had prepared a binder for Lynn in advance in case she might also come to Blackwell when she gets older.
- Kate's sisters and her father are two optional dialog choices that are thought to be the deciding choices on whether or not Kate will attempt suicide.
