Season One
The first season cast consisted of Nick Knight, Jeanette Ducharme and Lucian LaCroix - all vampires.
Dr. Natalie Lambert, Det. Donald Schanke and Captain Stonetree made up Nick's mortal police department circle.
Season Two
In season two Nick and Schanke got a new Captain, Amanda Cohen, and LaCroix showed up alive (well, sorta) and found himself a spiffy new career as a talk radio DJ on CERK. His new persona, The Night Crawler! The name of his show why, Night Watch, of course!
Season Three
Season three brought many controversial changes that the die-hard fans are still arguing over. Nick's beloved partner Schanke and their Captain, Amanda Cohen, were both killed in a plane crash. Nick got a new partner, Tracy Vetter (who meets up with her own handsome vampire, Javier Vachon, her first night) and a new Captain, Joe Reese. Further changes to Nick's little world included the fact that Jeanette left Toronto leaving LaCroix to run The Raven.
