Your not stupid. I'm just a giant nerd. I also named the Dark Brotherhood Initiate: Debby. There are 2 DBI's with exactly the same name. One's a boy, the one I use is a girl. The boy has an annoying voice. Funny thing, there are only 3 followers in the game that level to the max(81) with you. Both DBI's and someone else. The follower system is broken with this game, so most followers are locked on the level you load their zone first at. You can fix most of them by using this weapon with a random effects, and change them into a chicken, and when they turn back they'll be at your level. Only both of the DBI's and some other horrible follower that caps at 30 will actually have stats that level with you. Both of the DBI's are also flagged as essential, meaning they can't die at all. So they're the best followers in the game.
Saying "Fus Ro Dah" doesn't make you a nerd. Pretty much everyone who's heard of skyrim knows what that is. If you can explain what these are, I'll agree with you. Yesterday, I Fus Ro Dah'd my follower, the Dark Brotherhood Initiate, off of the Throat of the World, next to High Hrothgar.
WHO HATH SUMMONED ME?!?!?! I've just finished the Dawnguard DLC for Skyrim, and did some of the god-y quest in the game, so I'm a bit jacked up on it. Couldn't miss that opportunity. What's up with you.
