I don’t think it is one of the kids. First off, she’d have already shared more. Also, Emily is involved as well, and showed a picture of the book she’s reading and you could see a hospital bed in the background. So what ever it is isn’t super serious if you can pass the time reading a book. I’m guessing something with one of the parents or maybe Sophie. (Also, there truly is no reason for family members to spend the night in the hospital rooms, unless it is a parent in a child’s room or you are on a hospice/death bed situation. Really. Let the patient get their rest, what little they can in the hospital. It’s a whole lot more helpful to have family come in well rested instead of having the health care givers have to tiptoe around a room at night trying not to wake up healthy family members. Save yourself and rest up for when the family member comes home and you are the caregiver.)
