I couldn't find a better thread to post this in so apologies in advance but this thread seems to be the most relevant currently. This falls under Pokemon X and Y mysteries but there isn't a thread for it so I will post here.
I feel there are a few things in game that we should be working on trying to solve as a community as it seems as though there are a few things in game which have not been fully unraveled yet. Of course these strange in game occurrences might not even lead anywhere but the more people trying to get answers to these, the better chance we have. Remember the tourist in the hotels of Kalos which gives the Strange Souvenir item? You have to speak to him four days in a row to get the item and he changes location every day. It's an obscure way to get this item and I feel there are other little events in this game that the community have not figured out yet. I'll list them below. (There really should be an unsolved mysteries thread.)
1. In Jaune Plaza in Lumiose City, there are two female characters. One mentions that there is a Lava Dome pokemon in Jaune Plaza. Another mentions something about mimicking pokemon cries in the plaza. Has anyone been able to bring a Heatran to this area yet? I can't because of pokebank's delay.
2. In Lumiose Station there is a note on the back of the timetable screen furthest away from the entrance. It mentions that someone needs help and asks someone to wait in the usual spot. Interestingly there is a little boy nearby who says that 'it should be around here somewhere'.
3. In the Lumiose Press building, the editor in chief left a memo on the desk saying that she is gone deep into the mountains to pursue a mythical pokemon.
4. In the Parfum palace there are statues of Reshiram and Zekrom facing one another. There are 4 sets of hedges in the area. When viewed from above these 4 hedges are shaped like a Solrock, a male Pyroar, a Chandelure and a 4th pokemon or shape which is tough to figure out. Perhaps if we bring the four pokemon here, we could activate something in relation to the statues.
5. The locked power plant. There are three locked entrances on route 13 which cannot be accessed. My gut feeling on this one is that it is related to an unreleased event.
6. The ghost girl in Lumiose. When you enter an empty building, there is a ghost girl which floats across the screen and says "No, you are not the one" and then disappears. She has the appearance of a Hex Maniac. Interestingly, there is another Hex Maniac girl on the 4th floor of the Hotel Richissime in Lumiose City which says something like 'Don't talk to me or I won't hear the elevator". I tried bringing a Rotom to her (as Rotom messed up an elevator in a previous game but this doesn't do anything.)
Anyway that's all for now, I'm sure most of you are aware of some or all of these but I wanted to mention them for those who never heard of some of these. I think we should brain storm and try to figure all this out. Personally I think 2 and 6 may be linked but really I have no idea. I have been trying different things in game to try to get an answer to any of these mysteries but have come up short so far. There is also the mystery of the train station in Couriway Town that goes nowhere yet but again, I think this could be for an event or something. If you need more information, this video is pretty good

EDIT: possible breakthrough on number 4. The fourth hedge may not be a pokemon at all. It actually seems to resemble the Strange Souvenir item. I saw somebody mention this on youtube and it seems like a pretty good guess. Unfortunately I have not obtained the Strange Souvenir item in my current game (lol I came unprepared XD) I will try to bring a Chandelure, a Solrock and a male Pyroar along with the Strange souvenir to the Parfum Palace as soon as I can but it may take a couple of days. If anyone can try it today, please let us know if anything happens.
