Number 4 talks about a secret message at the lumiose train station, well I found another secret message at one of the chairs in the station in couriway town. It reads "To the person reading this: What are you like now? Did you become who you wanted to be? For starters, what was the person you wanted to become even like? I don't know, but it would be wonderful if you can boast that you're living each day to its fullest. To future sycamore. From the sycamore dreaming of the future." Doesn't seem to mean anything special, just something supposedly from prof. sycamore. Thought I'd mention it anyway though.
