You and Ghost were at the supermarket, buying food.

From one moment to the next, Ghost disappeared from your sight, but you thought it was just because he wanted some food.

You were in the fruit area, looking for apples.

Then, Ghost returned. "Honey, look how pretty." He said smiling, showing you a baby outfit, smiling.

Ghost when he wanted something used to give hints about it, like in those moments. He wanted to be a father, obviously with you.
