- The massacre of the resistance group and later the murder of Tel Varon and his girlfriend in "The Way Back". It's not that their deaths are particularly sad: it's that they don't matter. No one will notice, no-one will be outraged and, after a little Orwellian editing, no-one will remember they ever existed at all.
- In "Mission to Destiny", Cally passes out from Knockout Gas, but not before speaking a single word telepathically: "Alone..."
- From "Pressure Point" - the loss of Gan when he's crushed to death by falling debris from an explosion. It's a truly chilling moment as he dies yelling at Blake "Go! I'm not worth dying for!" before being killed. Up till this point the protagonists had spent a series almost emerging unscathed from such situations, often laughing off the after effects.
- "Children of Auron" has Cally being reunited with her twin sister Zelda. Who then dies.
- Servalan crying over the deaths of her clones.
- The death of a COMPUTER in "Terminal". Poor Zen..."I am sorry. I... have... failed you."
- Just to make it even sadder, Vila points out that this is the only time Zen ever refers directly to himself.
- "Rumors of Death" gives us the Avon/Anna backstory. Avon's failed bank fraud resulted in the capture of his lover, who was subsequently tortured to death. Later he learns that the Federation only came after them because they thought he was political, and while trying to get revenge on her killers he runs into Anna herself, who's still alive because she was a high-ranking Federation Security agent assigned to watch him. She tries to kill him and he shoots her dead. Happy endings, eh?"It wasn't all lies, my love."
- Cally's death in "Rescue".
- Related to the above, in "Sand", Vila gets angry when her name is mentioned.
- "Orbit", where Avon and Vila can't gain escape velocity in their shuttle at the current weight, so Avon tries to kill Vila, who happens to match the weight. While Avon's looking for the hiding Vila, you can see tears on Vila's cheeks, from a deleted scene where he was crying.
- Finally, of course, comes "Blake", one of the most tragic series finales ever seen on TV.
