Carole Littleton

Carole Littleton was portrayed by two different actresses.

Arlene Newman-Van Asperen portrayed "coma Carole" in the 

Season 3 episode "Par Avion".

Susan Duerdan portrayed Claire's mother in post-coma episodes.

I have written to both Ms. Newman-Van Asperen and Ms. Duerdan,

requesting autographs.  I'll update this post if/when I receive a response.
