There are a few things which don't make sense to me.
Or maybe I lack information.
Does anyone here know if the members of the slave army still have their balls?
Cause what sense would it make to remove the balls of male warriors? Then they'd all become feminized and lose most of their strength.
And what about Theon? Did he lose his balls?
If yes, then why does he still have a beard? I mean did the author simply miss the fact that without balls he'd no longer have any facial hair?
And what about his voice? Why doesn't he sound like a woman by now?
