Serious doubts on the broken ankle. If you have ever broken an ankle or know anyone who has, then you know that shit is incredibly painful and it's not something you can easily fake. Any movement, no matter how slight, would cause a ton of pain. Her ankle would also be incredibly swollen and the pain would continue to worsen the longer she goes without getting it treated. There's no way she would be able to sleep without a cast unless she has some serious pain meds on hand.
She's either flat out lying, or it's just a bad sprain. Either way, Nurse Bonnie better get use to Kindless always being ill and needing to be taken care of.
