Now, I know. Bla bla, Aether foundation is evil, bla bla, but I have a different idea. Notice how both the leader of Team Skull and Laba have VERY similar poses, crouched downish. I believe that Faba may be the leader's father, and joined Aether so that he could use the Ultra Beast and the Pokemon for the good of Team Skull. And if the Chinese leak is right, I think that Blue/Gary may also be in Team Skull, but ends up revealing Laba's secret, being that Prof. Oak sent him after getting Samson's suspision.
