So, correct me if I'm wrong, but since Carolan didn't become Challenger's second officer with Geordi's arrival, wouldn't she more or less fill the role of third officer in addition to being the senior transporter chief? Granted, the book never said she was, but one could easily guess that she could have been since she would serve as XO when Geordi took command. 71.185.227.7 00:13, June 3, 2013 (UTC)
