Mayor Peter Stockmann, the Doctor's crafty brother, is a classic antagonist. The Mayor does everything he can to stop his brother from revealing the truth about the polluted Baths. He turns the Doctor's main allies, and eventually the whole town, against him. Ultimately, the Mayor is successful; Dr. Stockmann is never able to reveal the whole truth about the Baths. Of course, in the end, all the Mayor's machinations only open his brother's eyes to an even deeper corruption that must be exposed. We have a feeling that there's no end in sight to this sibling rivalry.
