To Kill Dragon or Not to Kill. Both Options (Witcher 2 Quest | Geralt Boss Fight)

Appearance of a dragon during a summit of mages and a consequent battle with it. Both options covered: killing a dragon and letting it live. Watch more Witcher 2 videos: http://bit.ly/RTs7x4... Geralt ran for Sile de Tansarville as fast as his legs would carry him. He could hear the sorceress' voice in his head, and the more she said, the more he wanted to silence her. Yet Síle held one more trump card - the dragon.
If Geralt choses to kill the dragon:
Defeating the dragon was one of Geralt's greatest feats. It was a difficult fight, even the slightest mistake could have meant instant death. Yet an ever harder task now awaited the bruised and fatigued witcher - he had to settle things with Letho.
If Geralt choses not to kill the dragon:
Geralt spared the dragon's life, or perhaps I should say he spared Saskia, even though the sorceresses may have still had a hold on her mind. In any case, it all played out in agreement with the witcher's code (and it matters little if this code is a fiction or not), which forbids the slaying of sapient beasts. The dragon was not Geralt's true enemy - unlike Letho. It was him that Geralt had a score to settle.
