Lorelei (Paradise 5)

From Tardis Wiki, the free Doctor Who reference

Lorelei was a member of Paradise 5 hostess crew. She talked to the Sixth Doctor about the fish in the aquarium. She ended up being in on Gabriel and Michael's scam. The Doctor managed to knock her out when she was preparing to kill Peri and Stella. It is unknown whether she made it off Paradise 5 before it crashed into Targos Beta. (AUDIO: Paradise 5)
