227: I killed Sile for the first time in my last playthrough. Felt so bad that I reloaded the save just to keep her alive.
There are just so many things unknown about her. Why does she wear such a strange, pointy hat all the time? What is that tattoo of? Does she like long walks on the beach?
These questions will be answered in Witcher 3, or else. Sure, she's kind of psychotic and tries to kill you with a dragon, but that kind of behavior is flirting when you do it to someone who hunts monsters. It's a classic "I only sic a dragon on you because I love you, baby," scenario.
I have let her go splat twice. However, I may let her live the next time.
I let Letho live both times, but did do a saved game to see if I could kick his butt. I did on the first try, so this settled whether my level 35 witcher was the better badass. But, then I reloaded and let him live. The actual killer was the royalty in Nilfgard; Letho was merely the blade they used. I felt that I had settled my debt to Roche by tracing the real culprit. And, darn it, he did save my women.
