Rozlynn Wells is a newcomer to New Orleans. Her last place of residence was Atlanta, and she came there from New York. Her accent is peppered with "my guy" and "dead ass", but it's not born and raised New York from the sound of it, something more Midwest. She hasn't stated why she's in town, and she doesn't seem to be attempting to procure a real job just yet. No W-2s for her.
The Lost will know that she has some experience in the medical field, and will aid her fellow Changelings.
The Underworld will know that she has a reputation as a street doc. No questions asked.
