This episode shows the first appearance of Zack who will be pivotal to the series later on. Max and Zack\'s teamwork during the fight is excellent despite the 10 years of time they\'ve had to forget everything which is exactly what Max has been doing.
Vigelsang coming back just to get killed was pretty pointless unless they just wanted to show how ruthless Lydecker can be when it comes to his kids. Valerie, logan\'s ex coming back to extort money from him was also pretty useless as it didn\'t make Max overly jealous or have any real impact ont he characters or the storyline.
The writers on this show need to come up with some new names. Zack in this episode says his name is is Sam which is Max\'s clone\'s name in Season 2 \'She Ain\'t Heavy\'. Max uses the name Rachel when she goes to that conference which is the name of the girl Alec was in love with in \'The Berrisford Agenda\' or maybe they were using them on purpose. who knows?
