The thought occurred to me that Victor Bergman, Paul Morrow, and David Kano did not die after Year 1; instead, Koenig assigned these men to develop a "Beta site". This site would be used to mine materials to further develop itself, but also to provide a remote research station and a new source of raw materials for Alpha.
Works for me, it would be nice to see these characters again. Maybe Tanya is there too. This would be a good explantion as to why Sandra disappeared for much of S2.
That warranted the introduction of Tony Cellini
Wasn't this because an Italian station was fronting some of the money, on condition that Italian actors guest starred (the guy who played Mateo in Troubled Spirit and the fellow who played Luke in Testiment Of Arkadia being the other two)?
