The reason all the workers had been called into the Temple that day, was because Pam wanted to delegate the tasks that the workers would have. Most of them were to become teachers, a few just simple guards to keep an eye on the kids.
Since this wasn't their original role on the island, there was no one specialised in these types of areas, or at least they hadn't been trained by anyone how to do so properly. However, everyone saw this as a temporary position before having to go back to the village later on.
Names would be called one by one, and people were elected on a volunteer basis. Peter wasn't really paying attention and was too busy trying to think where Vorden would be. According to Jazz, a big type of event happened, and during it, Vorden as a worker of the Temple had caused quite the stir.
'Did he get put away, locked up for trying to free these kids? Do these kids really need saving?' Peter thought.
