Mia (Emmanuelle Vaugier): Now
Emmanuelle Frederique Vaugier started her TV acting career in 1996, when she played Maria Alcobar in a 1996 episode of Highlander: The Series.

Lisa (Denise Richards): Then
Lisa and Charlie shacked up together in season 1, only to part ways on account of Charlie’s commitment issues. She shows up again in season 2 with news that she’s engaged, which propels Charlie to disguise himself as a reformed gentleman. Lisa and her new love call it quits and she gives Charlie a second chance, only to call things off for good for the same reasons that plagued their union in the first place.
