Thanks to my source SL for this info.

Russell
Late 30s, a brilliant mathematician and deep thinker who is capable of great insights and has a tremendous knowledge across various scientific fields. He sometimes struggles socially by being too direct and disconnected in his interpersonal relationships. While an empiricist by trade he is humbled and fascinated by the magic and mystery of all in this world that cannot be explained by science.
Starts with Episode #401 -August 19, 2007 in Hawaii).
RECURRING ARC WITH A POSSIBLE OPTION FOR SERIES REGULAR FOR NEXT SEASON;

Charlotte:
Late 20s. Very attractive in a naturalistic, athletic way, her looks are only one small part of charms. Precocious, loquacious, and funny, Charlotte a very successful academic who also knows how to handle herself in the real world. On a personal level it is hard to crack the hard shell of poise and certainty around her, but when it DOES crack its like an egg; lots of repressed and pent up emotions spill out.
(Starts with Episode #402 - August 29, 2007 in Hawaii).
RECURRING ARC WITH A POSSIBLE OPTION FOR SERIES REGULAR FOR NEXT SEASON.
