"Face? Oh, right! Forgive me," the fake grandpa with the terrifying face said after being reminded. His one hand swiped in front of his face and a more normal face of an old man appeared. The old man gave him a big smile.
Jack didn't respond in kind.
"What the hell, old man! Do you get off from scaring a younger man like me?" Jack scolded.
The old man gave him a wry smile, "young man. It is called a test of courage. In order to test your courage, of course, it has to be something that frightened you. All this is constructed from the images in your memory. It is simply manipulated to become something that is most likely to terrify you."
"What is the requirement for me passing?" Jack asked. He didn't really understand how he had passed the test.
"When you decided to overcome your fear and faced it instead of running from it. Or in your case, punch at it, I might say," the old man replied.
"Pretty simple," Jack commented.
