So, I was just fiddling around in the College of Winterhold, assaulting Ancano, just looking around. I have Apocalypse spells installed and have mastered almost all schools of magic. While fighting Ancano, I used the Illusion spell Compelling Whispers and got Savos to fight too. But when I used Spectral Warband, something must have gone wrong and the Illusion Savos became real. He didn't do much, mainly followed Savos around, but didn't die during the quest. So now I'm Arch-Mage and found the second Savos poking around in my/his/our quarters, and I used addfac to make him a follower. Like they say, two Arch-Mages are better than one!
He even said unused dialogue, "Greetings Arch-Mage."
