+1 to both. I thought about Kagha's heavy chest and thought it would be cool to be able to put the evidence back and relock it. Then, allow the players to suggest to Rath later that he could search Kagha's things as proof she is a Shadow Druid Initiate.
You know, make the player provide some sort of additional proof shes doing bad stuff instead of everyone just being like, "Oh! You know the truth. Well, I guess we're caught now. Better just reveal that it's true." Why not have some denial and the player needs to prove it. Finding those documents in her heavy chest would sure be extra proof.
