She understood the laws applying to whales and knew what the whaling industry would be doing wrong, when they do. Since she's not old enough to make a difference, politically, she has to tell other and keep an eye out. Thus, my reasoning of thinking she was to be a watchdog.
The other explanations make no sense, but the watchdog does. Watchdogs means to watch the activities of the lawmakers and people in the government and report back if its illegal or causes problems. which is exactly what Taylor is doing. Wacthing the officials and reporting back to her family and friends.
