After a long argument, they eventually found common ground. Jake agreed to let her and her allies live here, and in exchange she swore under Contract not to harm his Villagers and to defend the latter in case of attack.
He also forced her to reveal her Initial Role: Clairvoyant. The details of this Role were as follows:
[Villager: Clairvoyant (Unique)(Upgradeable): Can see the Roles of one participant of their choice each Cycle.]
This was only at level 1, though. No matter how hard Jake tried to convince her, she refused to disclose her current level. He did, however, insist that she reveal the circumstances of her Monster Role, or their previous agreement would be void.
This precaution saved him a lot of trouble later on, as it gave him a salutary insight into what they might face in the near future.
