Some of the modifiers for the contract are shit like:
The character learns a fear not currently concerning the target; The character learns a specific kind of fear; The character discovers a fear the target recognizes but generally keeps hidden; The character finds a fear the target hides even from herself.

So we can either like. Roll for the specific fear we wanna play with or just fuck around and grab something stupid and intense and Gil can feel bad about setting off an actual PTSD response later.
