Plot cards - triggered or passive?

By Laban Shrewsbury, in 2. AGoT Rules Discussion

Probably a dumb question, but is the effect on something like Fury of the Wolf triggered or passive? If I don't wish to have the effect, i.e. kill an opponent's character, take place can I choose for it not to happen by not triggering it?

Suspect it's passive (it doesn't have Any Phase or Response) and always happens, but just want to be sure.

Yes, the effect is passive. And therefore also takes place before any responses.
