The crux of the problem

Aldrich felt that his head was spinning, this was worse than he expected. He still wasn't sure of what was happening but it clearly affected Irene's mental faculties badly.

Aldrich could just turn around and pretend that he didn't see anything but Irene saved his life, he sure as hell wasn't about to leave her like this.

Moreover he wasn't just a powerless farmer anymore, he could do something, "Irene… I don't see anyone here besides the two of us…"

Irene looked at him in confusion, "stop joking around and come eat, don't worry about grandfather he will eat later on his own."

Aldrich stood in place, "I'm serious, your grandfather is not here."

"Not… here?" She stammered like she was shocked all of a sudden, "oh, yeah. My grandfather has been… dead for a long time."

"Dead?" Aldrich repeated.

"Yes, dead. I wasn't even born when he died... But he's here now. He comes to visit me sometimes. Can't you see him? He's right there!" She screeched and pointed up front, at the air.
