I'm referring to the 3x17 episode "Unity." Wouldn't you think she would jump at the extremely unlikely chance of being rescued by a Federation starship? It hadn't been that long since Wolf 359.
If not that, wouldn't she be duty-bound to go with the Voyager crew? I mean, she never officially resigned from Starfleet and by her not going with Voyager, I would think of her as a deserter.
