My area lays within Syrians, but if there's blood, you should probably separate them. Now, I don't really know about dwarves. But a hamster is a hamster. They could be the best of friends, and then suddenly all after one another's blood. I saw a dwarf hamster in the pet store years ago who was MISSING AN EYE undoubtedly from a fight amongst his "friends". In fact, he was so frightened of his "brothers", that I think he was the one that chewed a hole through the pexiglass separating the tank of dwarves and the tank of Syrians. And then I watched him crawl through the hole and shudder in the corner of the Syrian tank. I know they *typically* get along and be social, but if your boys are drawing blood, you may need to separate them into individual cages.
Does he squeak every time Soren is near him? That's a very frightened, and unpredictable animal. That's the worst kind of pet to have; because they can do damage simply out of fear. It's not easy to soothe a fearful animal if their source of fear is around, and it seems like Kier's source of fear is Soren.
I relate Russian dwarves to a game of 50/50. I've heard some good about them, and some very bad. I've heard some are sweet and gentle, and just the best types of pets! But MY experience with one, and some of the other opinions I've heard, they are very nasty. The one dwarf I had(and I did NOT get her from a pet store, she was one offspring of my friend's neighbor's hamster that had a litter, but the mama was probably from a pet store), probably wasn't socialized - perhaps you were lied to and Kier and Soren aren't brothers at all - perhaps Soren came from a very socialized environment and Kier did not. I wouldn't be surprised if you were lied to, I don't trust Petsmart's honesty, ethics or integrity, I don't think they have any to be honest.
There WILL be stress from being in a new place, but it's possible their true colors are shining through, and that they just won't get along.
