Specifically, the act of not going through with one. I ask this having recently watched Amok Time - Spock's arranged wife, T'Pring, rejects him, choosing instead another Vulcan male, and using Kirk as a way to get Spock out of the picture, via Kal-if-fee.
Indeed, Sarek must have done the same - he married Amanda of his own volition, so he had to have rejected an arranged Vulcan mate. Did he force his bride-to-be to a battle to the death, as well?
And yet, there's Enterprise, wherein T'Pol is arranged to be married to Koss, but doesn't want to, much like T'Pring. And to solve this problem, she... just doesn't do it.
So, why on Earth did T'Pring use such a brutal method of breaking off the marriage if it doesn't need to be done that way? And why would the Vulcans keep up a tradition like that?
