Though she looks young, Nessa is actually older than most communications officers. Most of her peers have either made Captain or retired. She has reached the point where she accepts she’ll never have her own ship but she doesn’t have to like it. There is a fair amount of regret and resentment buried underneath her charming, calm exterior.
She has a lot of experience having done this job for over 20 years. As a result, she is rarely surprised and finds it easy to adapt to most situations and most people.
For most of the time she is cool, polite, charming and efficient, but if her mood turns or the stress builds, the resentment comes out as biting sarcasm.
