About bonds for Mega Evos
The bond between trainer and mon may not have to be "friendship". (As it was pointed out earlier, friendship is counter productive to the Shadow process.) I believe it could be possible that the bond between a Cipher and a potential Mega Shadow mon could be "a shared desire or goal" - i.e. both want to cause pain for the Evulz, both want to take down a certain person, etc. Though I say it would be possible for a Shadow Mega to happen, the draw back to a Shadow Mega would be that since the bond would be superficial, the Mega Evolution would be weaker/ harder to maintain/ or whatever. However, if the potential Shadow Mega and Cipher bond went into Unholy Matrimony/ Villainous Friendship territory, the bond would likely be stable.
About Fairy Types
In-game it mentions the fairy type being recently classified (or something similar). IRP Someone could "discover" the Fairy type via the discovery that pure Fairy type mon like Flabébé, Spritzee, and Swirlix, have different genetic markers that while present in other mon, are not near as predominant. The discovery of these makers would could cause scientist to re-classify them as a new type. This would lead to scientists re evaluating already existing mon to see if the qualify to be reclassified as a Fairy type mon.
