I find it a little weird that Gillan had Sin Purge instructions hidden so well in her shop, especially considering that one sample is a leaf clipping. @Pokemon Trainer Sarah, I don't suppose you could interview her about the instructions - ask if she hid them there, and if not then who could have? @Suicune's Fire, you'd be good for this too, since you're same stage and neutral to Gillan (+1 rapport which is what Sarah had). We might get something useful from her reaction at the very least.
