Volunteered

Lauren opened the door. There was a room inside, and there was another door at the other end of the room.

Therefore, Lauren inferred that when she opened the other door, they would arrive at the next room.

Each room should have a different ghost.

There was a wardrobe and a bed in this room. On the bed, there was only a blanket. It did not bulge, so it looked like there was nothing in it.

They walked to the other door and took a look. There was a note on the door that said, "To open this door, please find the key."

Lauren tried to twist the doorknob, but it would not open.

She turned around and said, "We should be looking for the key in this room."

"What kind of haunted house is this? It's obviously an escape room, and we're even playing with ghosts."

Ever since Quinn entered the room, he had not stopped talking. He was either screaming or ridiculing the others.

"I'll do it," Bryce volunteered.
