The Surveillance is a number tracked on the surveillance dial. There is only 1 surveillance dial, which is shared by all characters. 

The Surveillance starts at 0 in each episode. 

When you trigger Surveillance, increase the number on the surveillance dial by 1 for each point of Surveillance. 

Whenever the Surveillance meets or exceeds one of the thresholds on the Surveillance card, the threshold effect is resolved. See Surveillance card for details.

Clarifications:

• The surveillance cannot be lower than 0 or higher than 99. 
• If the Surveillance is set, reduced, or increased to a specific value and Hope is on the Surveillance card, simply leave that Hope on the card. It does not change the value the Surveillance is set to for the time being, but will ignore Surveillance triggered later in the game.
