She won't take kindly to being addressed as either. Captain's a rank she's yet to achieve, a position high on the Starfleet ladder than she wants to climb at this point. She's content with being a scientist, with having a life outside of what she does for a living. She doesn't think she'd be able to maintain that were she a captain, especially in the situation Commander Chakotay claims they're in. (Spoilers: She's right. She doesn't. She can't. She won't.)
