I don't get the logic. The child is not actually related, but looks like him. And if they were related he'd be a bastard as they point out, who typically can't become heirs. But is also younger than the two. And again he's not even related. What's the threat?
where is erin right now? seems like he was pretty much full steam ahead on the rumbling but they've had alot of time to run around without a peep from him
