Nail man

Nailor or Naylor or Nayler or Nailer is Jackson's assistant, and as nobody really knows how to spell his name, will subsequently be referred to as 'Nail man'.

Nail man is Jackson's right hand man helping and supporting him in his work. While Jackson has had an often stormy relationship with the Kingdom, Nail man has remained generally pleasant and amiable towards it, even referring to David once by name, much to David's surprise.
