Twenty years later... wow, that was... kinda sucky.

HAH! I call “wrongo” on you and zap you with my Star Trek disc gun.

The blonde was Lydia, played by June Chadwick. In the episode you (badly) describe, Diana was married to Charles and were presented with matching ceremonial bowls. The bride’s bowl was poisoned but at the last moment (in a contrived random plot twist for which V was well-known) Diana breached etiquette and gave the bride bowl to Charles. He drank and keeled.

The woman sent off in the space coffin with Charles’s body was a patsy convicted of the murder on faked evidence.

I bow to your superior knowledge, but I’d like to get geek’s credit for fairly accurately remembering that scene. Besides, that was all from memory.
