I noticed that the chateau and the mansion are on different sides of Mt.Cornet. After I figured that out, I thought "Hm, wait I remember something about the mountain splitting Sinnoh into two halfs." So then, I went to Veilstone and went into the house with the girl that tells you about a myth that says Mt.Cornet split Sinnoh into two halfs. Dialga sleeps upon the peak of Cornet. I then looked at the map of Sinnoh. I diagonally connected the location of The Chateau and the Mansion to see where on Cornet, they intersected. They both hit at the one part of the map where it stoppes, goes left and then falls south. The Spear Piller is a bit south from where they intersect though. While walking through Mt.Cornet, I saw alot of pokemon that Backlot said he had in his garden. By finding this, I also figured that alot of pokemon in Eterna forest are found in his garden. I think he takes pokemon from Mt.Cornet/ Eterna forest and then places them in his garden, hence him telling his butler to do something. But there are also other pokemon that aren't in Eterna or Mt.Cornet that can be found in his garden, such as Burmy, Mime Jr. and so on. But what I can't come to understand is why he would steal pokemon from their natural habitat and give them away at his garden and to top that, he doesn't sell them!? That is a bit odd.
