Odd Voice Mail from FMIL

I discovered voice mail from my FMIL after 10:30 last night. She didn’t go into specifics but said, she’d had an accident, wasn’t doing very well, that her step-son would be arriving soon (but she couldn’t remember when), and could I please call her. I’m 98% sure she’s talking about her fall last month. She and I have talked four times since she fell, and discussed the fall each time. When I call her back, I will use the conversational litmus test I employ with my mother: “Hi Mom, I’m returning your call.” This always lets me know if mom remembers if she called me, and for what reason.
