Guest, Child Maurice, not really. It does have the commonplace looking over the castle wall but depending on which version you look at she either sees Child Maurice's severed head or has it thrown into her lap and Steward tells her she can use it as a ball.

As this cruel taunt is not in the 17th century English version some Scottish poetaster was possibly influenced by one or other of our 2 ballads under discussion.
