Worf: There are six trials we must face on the path to Kal’Hyah. This is the first – deprivation. We now begin a fast that will continue until the day of the wedding.

Julian Bashir: That’s four days away.

Martok: It is a short time, I know, but we must make the best of it.

Benjamin Sisko: What are the other five trials?

Worf: Blood, pain, sacrifice, anguish, and death.

Julian Bashir: Sounds like marriage alright.

Miles O’Brien: How would you know?
