I have questions on a particular 2+ Insane Condition card. For those who haven't run into this one yet, the rest of this post will be in a spoiler tag.
Insane Condition - Forbidden Words
1) We played it where both the player and her investigator could not speak. Is this right?
2) If your investigator has this condition, does this mean that you cannot perform any speaking interactions with NPCs? If so, could make certain scenarios unsolveable?
