When Abigail relates her version of what happened in the forest, what lends credibility to her story? Does Parris believe her?

Abigail warns Parris that there are rumors of witchcraft and that the parlor is packed with people. Parris tells her that he cannot reveal that he found his daughter and niece dancing in the forest like heathens. Abigail admits to dancing and is willing to accept the punishment, but will not admit to witchcraft. Parris fears that her "bad" name in the village could taint his own reputation and position in Salem.
