How Did We Get Here From There?

I missed a call from Cousin M today. She left a message saying that she had just talked to Mom. She said that Mom was very passionate about having Helen come to visit. Evidently Cousin B thinks Helen is strong enough to fly alone. So the gist of the message was that Helen will come by herself and stay for 10 days. Cousin M wanted to check it out with me because I would need to pick Helen up at the airport.

What? The only thing I can figure is that I'm missing some vital element to this plan. Maybe someone else is coming to help? Surely the plan is not to put Aunt Helen on a plane and leave her alone with Mom and Dad for 10 days?
