Seventeen, who emerged from the laboratory, joined forces with Nineteen and Twenty, who came in later, to surround the player without a number on their head. Seeing the player without a number falling into a disadvantage, he turned and rushed into the laboratory, simultaneously throwing out a mask—which, upon hitting the ground, caused the protective shields worn by the three numbered players to drop in unison, halting their pursuit into the laboratory.
The three exchanged looks, and Seventeen transferred a sticker prop onto Nineteen's new protective shield. Then they and Twenty left the defensive barrier, leaving Nineteen to enter the laboratory.
A faint white gas permeated the laboratory, potentially a poison gas, so the players entering all wore protective shields.
