 During the fight Connor and Duncan have with the "Tax" thieves one  of the men (Lachlan) picks up a rock as a weapon. As the McLeods go  on the defensive Duncan says to Lachlan "Looks like youve lost the  edge, lad". This is a reference to Adam Copeland (I) (qv)s  (Lachlan) "stage" name of Edge in the World Wrestling Entertainment.
