So, I've just finished the Companions questline. I took all 5 witch heads and used one on whatshisface and one on myself.

I've seen that there are future radiant quests that will allow me to help cure Farkas and Vilkas of their lycanthrophy (did I memorize that ridiculous word correctly?).

However, after curing them.. I'd still have one witch head left, and one fine ass archer werewoman. Does she simply not want to be cured, thus it's impossible?

Am I just gonna be stuck with a fifth witch head in my inventory forever?

She does not want the cure. Just put the head on a shelf somewhere, or on a Jarl's table. Looks nice there.

EDIT: I was able to drop the heads into a chest after I cured the old man, so it shouldn't be 'stuck' in your inventory.

She doesn't want to be cured. And you can sell the heads to an aclhemist. The fifth is useless.

So they can be. I wasn't too sure of this, and those radiant quests are far too boring to even do, gives me a reason to start them up again, thanks

Will anyone think of the poor Glenmoril Witches? Sacrificed so you can have a spare head.

Maybe make a scarecrow?
