Suddenly, Ralph’s landlord, Mr. Anderson, entered the apartment.

“Ralph, are you here?” Mr. Anderson shouted. “You owe me three months’ rent. Do you have the money?”

There was no answer. But Mr. Anderson noticed a light. He followed it and entered Ralph’s lab. The portal was still open. Curious, Mr. Anderson approached the portal, entered it, and disappeared. Soon, the portal closed and was gone.
