Oh so I had this idea randomly that maybe there's some guy/girl that starts to target them at the inn because they want to know what's going on and such. They can tick off Penelope in some way and she ends up teaming up with Crow(likely through bribery of food.) to find out who this person is and what they are hiding.

I figured the person could be a spy for the other kingdom and maybe they plan on trying to stop our characters in order to gain favor in their kingdom?
