Captain Tryla Scott: Captain, U.S.S. Renegade. Attained the rank faster than anyone else in Starfleet history and was something of a legend. Was brought into Captain Walker Keel’s conspiracy when he suspected high ranking members of Starfleet had fallen under an alien influence. It is unclear when Captain Scott herself fell prey to the alien parasite but had been turned by the time Captain Keel convened the cabal members on Dytallix B. He had brought Picard into his circle and although he didn’t believe him, she reported that to her brethren in Starfleet. They were not surprised by the time Picard showed up at Starfleet Headquarters. She joined Admirals Savar and Aaron at the reception where they revealed their true nature to Picard. Scott was incapacitated by Picard and Riker at the reception, where the alien parasite fled her body once she was incapacitated.
