Okay, time for some catch-up.
I wanted to change his name, too, seeing as "Kelly" doesn't really scream one-eyed killing machine. But he said anyone who wants to make fun of his name can say it to his skull-tatted up face.
You just need an intimidating last name. Like
this guy. I assume he's some sort of towering undead creature.
He's a nice guy, really. Though he silently judges Shinon (he thinks he preens)
He would think correctly.
I wanted to ask: Do Berne and Barnaby have quests on the board? Because I've never seen one for either.
They both have an escort quest, they tend to pop up once you start raising their affinity, and usually show up on the Gran Soren inn board. Maybe Ser Berne's is in the Encampment, though. Ser Berne also has a post-game quest where you can duel him, something I don't believe I've ever done because I didn't know it existed. It's possible I did it on my first playthrough, but I really don't remember.
Oh and I listened to his voice briefly in English and OH MY GAWWWWD I almost killed him it was so bad 
I still remember my first encounter with Julien. "Oh, well he looks rather charm--NOPE"
Also, I have Zihark right now (forget who he belongs to) and I love him. Although he is kinda like glue, isn't he? He is always right on top of me! LOL
This actually happens to me all the time. Sometimes he's switched to guardian, sometimes he's still challenger/scather. He is literally stuck to my arisen and will run against her even when she's not moving. I don't know what's causing this. A few support pawns have done this as well. Might be a bug. He's loveable, yes, but we still need our space sometimes.

Does DA bring the base game? .o.
Dark Arisen includes the vanilla game, yes. If you have a save with the original DD and use that save data to start DA, you'll get the unlimited ferrystone and possibly a bunch of armor, I don't remember.
