Some questions... (Spoilers)

[Metroplex]

You know that paladin guarding the main palace in verona that you need to defeat so that you can then duel the usurper king and that if you spare his life he can be found at the pier... well, how do you actually kill him, I try to see if there is a quest to actually kill him but he just disappears after some quest where I am sent to question him.

What about that Idiot dude that actually offers you some magic water that turns out to be a trap as the cave is occupied by a dragon, if you spare him, is there a quest to kill him? Or should I just kill him as he isn't useful later on?

At the end of the game there is a text that says: See you later for a new adventure, or something like that, so does this mean there will be another KB game later on? I really hope so, This game deserves a trilogy just like the Prince of Persia...
