Ensign Larissa Knowles is the bearer of bad and better tidings in the penultimate episode of the series. She reports on the failure to destroy the Magog World Ship, but also restores Jillian Rhade to Telemachus Rhade. She seems, from the fact that she was sent to Tarazed by Dylan Hunt, to be a member of the Andromeda Ascendant's crew. ("The Heart of the Journey (Part 1)")
Larissa Knowles is played by Sarah Edmondson.
