Brenok...Well, he surprised me. He hates the Klingons, he hates them for what one of them had done to him, but he didn't want to destroy this ship--not this
way. (Initially I planned Klesh to leave alive and something else happen to him later, but he didn't seem like a type that runs away. He was not a coward.)
As for Toral, I think he didn't realise how much he loved her and how much he cared until that moment, until he lost her.
Ronus's choice? Brenok will ask him directly.
