Re: whatever happened to these characters?
Yeah... I'm not too fond of the practice of just giving the character the actor's first name, although I have done variants (like "Vaylin Zaand" for Billy Van Zandt's Rhaandarite character from TMP, or Marcella DiFalco for Marcie Lafferty's character).
DeFalco is one character I could live with never seeing again. All I can hear is that flat deliver of the line "Vessel is floating free now. No forward momentum" and I just want to stuff cotton in my ears.
Marcy Lafferty apparently got the gig solely by being married to Shatner. It certainly doesn't appear to be because of any acting ability.
