In your own words how would you describe "Imprinting"?

When a "werewolf" finds their other half to make better "wolves"

A big pawprint left on your face! (Like Blue from Blue's Clues.)

The involuntary way in which a werewolf recognises his or her soulmate, the person best suited to continue the werewolf line with. It happens the first time the werewolf sees the imprintee after first phasing.
