@Synvael he killed to gain royal attention. Exactly. I expect that kind of behavior from well other people. Not Geralt. Just sayin'. And however, he "went a bit too far"? What? LOL he KILLED the guy! Poor bastard, he was just insulting!
And he dropped the duel with Istredd because he realized the mage wanted to commit suicide, not because he felt stupid. Even feeling stupid, he would have engaged that fight if Istredd hadn't given Geralt a glimpse he actually wanted to be killed...
That and the moment he went berkerk in the 6th book, (with his reasons) I can't recall other moments. I said he went
a bit too far, because he was also self-defense lol and also the character was not full built yet.
Are we talking about these trifles?
No, he wouldn't have. Istredd would. Geralt wanted to understand only. They made a deal to meet at dawn, yet Geralt is the first one doubting that decision, resigned.
- The magician turned pale, his lips trembling with nervousness. "En garde, I tell you! There is no time for questions, the time of questions has passed! Now is the time of the action!"
"I want to know. I want to know why the sword. I want to know where is that kestrel and why is it with you. I have the right to know. I have a right to know the truth, Istredd."
"The truth? Yeah, maybe you're right. Our rights are equal. The kestrel, you say? He flew by me at dawn, wet with rain. It brought a letter. Very short, I know it by heart.
Goodbye, Val. Forgive me. There are gifts that you can not accept me and not There is nothing with which I could repay you. It is the truth, Val. The truth is a shard of ice. Well, Geralt? Have I satisfied you? Have you exercised your right?" -
And yes, it's true that it was a suicide attempt for both, but while Geralt tried it before (it is guessed by Sapkowski at some point before the "fight") and then went to the sorcerer with no intentions of killing him, Istredd understood it lately when Geralt went away.
