“Be All My Sins Remembered” is episode fourteen of season two of Andromeda.
Beka gets a message saying that Bobby, a former crewmate of hers, and an old flame as well, is dead, and she is listed as the next of kin and has to go and identify the body.
Dylan and Harper (the latter to make sure said old flame is truly dead; he didn’t like him) accompany her on the Eureka Maru. When they enter the system, they get hit by mines. Whilst waiting for the Andromeda Ascendant to arrive, Beka tells Dylan about Bobby, which also involves the story of how Harper came to join her crew.
Bobby isn’t as dead as was made out, though, and wants the Andromeda to use its weapons for his cause.
