I've never met any of the cast personally, but I can say that a few people have met Stana and they have all said she is genuine, patient and sweet with the fans.  She always signs her autographs "To ____ (insert message) Hugs, Stana".  It's nice that she personalizes her autographs.  One person even said they found the cast on location shooting scenes for the season 2 finale and were able to get their picture taken with Stana.  Even though she had obvious places to go, she still took the time to take pictures and after each picture, she waited to mke sure the picture came out right on the person's camera. 

This is not my story, but a recollection of a story told by another member of this site.
