I agree it would have been most intriguing to see a PT Vicki ( played by none other than Alexandra Moltke, the quintessential Vicki ). Also a PT Nicholas Blair. It would have been interesting also to see flashbacks to PT 1967 or PT 1968, and see PT Sam Evans, PT Joe Haskell, PT Jason McGuire, PT Burke Devlin... Conspiciously absent from PT 1970 was Mrs. Johnson/Clarice Blackburn.
BTW the PT 1970 sure racked up one heck of a body count. Most of Collinwood's central characters bumped off: [spoiler]Alexis, Willie, Carolyn, Liz, Roger, Angelique,to name a few (I can't remember if Daniel, David's PT ringer, was killed in PT 1970 or not). Of course Cyrus Longworth and John Yeager also got knocked off. Poor Roxanne, PT Angelique's downfall, was MIA in Collinwood's conflagration at the end of the storyline.[/spoiler]
