Professor Cooke is a pony of principles; anypony who has known him well can testify to that. As an established history professor at Canterlot University, he knows the dangers of opening borders to a hostile nation; his anti-changeling stance may seem harsh, but the safety of Equestria comes first. It's not about the species; it's the cultural dangers of a society of infiltrators, liars, and saboteurs on Equestria's border.

He's going to stand by those principles for the good of Equestria. Nothing can change that, not even one of his closest friends turning out to be a changeling... right?
