Quote context

[...]

- General, this self-appointed tyranny of yours cannot be tolerated. What you have done before was bad enough: harassing everyone with your orders, forcing immediate burial without time for prayer or mourning.

- But now this... preventing these young people from leaving.

- Persecuting a dear and lovely girl like Thea, terrorizing her with your ugly, savage superstitions. I will not have it!

- There are other men here, sane men. They will know how to deal with you.

- I warn you, General. Leave Thea alone.

- What must be done, I will do.

- Does that include smashing the only boat on the island?

- I told you that no one could leave.

- And I told you, General, that your orders do not apply to me or any civilian. You haven't any rights over us.

- If you do anything else to threaten Thea, General... I'll forget that we've been friends.

- Thea. Thea, you must help me.
