The group of four was exhausted after the horrible ordeal in the underground rooms. When these people came to Anarkh, they were in a good mood, excited to see something interesting. Unfortunately, they never expected to become a part of the show.
Their clothes were covered in sweat, blood, oil, ammonia and general grime, so their body odour was quite unpleasant. Luckily, the special attendants waiting outside showed them to hotel rooms to shower and change clothes.
Of course, the simple shower did not feel like it was enough. After all, they had done a lot of gross things, like dissecting corpses to get the code for the door. Moreover, the strange bombs in the third escape room were filled with strange chemicals, and they were still lingering on their five senses.
