Blue Gender Question (Spoilers included)

In Episode 24, the High Council had protested against Seno, but only two of them were there. Later, of the same two, one gets killed and the other gets sent to Earth. What had happened to the others?

That lady wasn’t a member of the High Council. The man wasn’t either. They were just high-ranking officers who were adamant supporters of the High Council.
Four died in Tony’s attack, and the only one who lived was the woman with the twin.

I didn’t see the episode with Tony’s attack.
