So, while waiting for V12, i was thinking we could all try to deduce who put our little group in the Tournament of dreams. Spoilers below.
My top suspects are either Crescent or Amanda, Crescent is the manipulative sort as we all know and putting us in the tournament may be her way of guiding us in the right direction, and tampering with people is her specialty so editing some memories of the officials would be child's play
Amanda is in a perfect position to put us in the tournament , as the Scout and co-manager of the league she has ample influence over anything that would involve the Aevium League, and this tournament's prize is an automatic 18 badge invitation to the Elite eight challenge. It stands to reason she could arrange this scenario, but on the other hand she has no motivation to do something like this and she only seems to just learn Melia was alive right before the Grand Ball blows up.
Cosmia and Cosmet are other likely candidates, they can impersonate people and are working for Team Xen as far as we can tell, so they have the means and the motivation.
Anyone else have any ideas?
