Well, at the very least, Brandon should always carry the letter you need for the Naked Truth quest on him, such that killing him allows you to get the letter off of him. I'm not sure if this is currently the case or not.
In terms of the whole Tenebrium thing, don't really know what to say. The handling of the Tenebrium Ability is likely the single worst part of D:OS.
