I can't in God's name find to which quest this script belongs to:

ScriptName FollowerDeathScript extends ReferenceAliasDialogueFollowerScript Property DialogueFollower AutoEvent OnDeath(Actor akKiller)	DialogueFollower.DismissFollower()	EndEvent

...as you can see it sits on a ReferenceAlias, and the quest using the alias is pointing at the DialogueFollower quest. But using info doesn't point me to the correct quest. It's no hidden script either. Any ideas?

Maybe the Boethiah quest?

this apparently checks out a follower when he dies.

for details, just check where that property is pointing to (following beth's naming conventions, i'd say a quest named "dialoguefollower", and that quest or whatever it actually is then will have a funcion in it's script "dismiss follower"that's called here, so you can read whatever that does to whatever stuff from that function

Did you try using the papyrus script manager use info? On the CK toolbar, go to Gameplay > Papyrus Script Manager, find FollowerDeathScript, right click and choose "Use Info"

the thing can show info? coool )

Good to know, I'll check it when coming home. Thank you.
