Perhaps not, but at least a name. He can’t just be Reek (shout-out to Game of Thrones).I don't think we should add him to the casting list.
It can make things confusing when there’s several “Naugs” in the same scene.Doesn't need a name. We can just call all dwarves "Naug".
We could have each dwarf refer to him(her)self as Naug 1. And their nearest relative as Naug 2, then Naug 3 and so on...
