Edge of Night encounter -> helping cure insanity

By valvorik, in WFRP Gamemasters

In Edge of Night, one encounter notes the heroes gain favour if they help an NPC recover from insanities the NPC is suffering.

Mechanically, I don't see any way to help someone get over an insanity in the rules. So I'm assuming this must be a narrative action (e.g., show him his delusions not real he recovers) not a mechanical one, correct?

There's the Shallyan blessing 'Cure Insanity' in SoF.
