Sooo... Not finisher All the paths (Im beginning one for Iorveth right now), but I think I discovered an "inconsistency" in the story or plot...

At the end, when you talk with Letho, he mentions there were 4 Witchers: Him(Letho), Auckes, and Serrit+Geralt, following the "cavalcade". But those of you watched the last scene in TW1, will remember there was another (failed) attemp to kill Foltest. Geralt kills "that" Witcher...,

But who was "he", that "5th Witcher"... Any ideas? Is this a "plot-hole"?

He's never identified. Triss mentions a body in the beginning, if you talk to her in the tent, but all she says is that he had a Witcher's eyes. Unless I'm remembering wrong and there's been a second attempt at assassination and she's mentioning that other person.

I think the story writers just forgot about that when making the letho dialogues

You are correct that it's a plot hole.

it seems that way...

Not to mention that Sile decided to go after Aedirn first. Why send one to kill Foltest before Demavend?

Say what? you finished the game?

Yep, I did. As I understand the plot, Sile had Letho kill Demavend first, then Letho went to kill Foltest at La Vallette's castle, for his own reasons.
The attempted assassination in TW1 occurred before Letho killed Demavend.
So again, where does this assassin and this attempt fit in with the storyline in TW2.

Maybe the Nilfgaardians sent someone to kill Foltest first, and after that Witcher failed, they sent Letho Serrit and Aukes.

its not the only inconsistency.

Intro, interrogation- Roche is surprised to hear about the elves. Yet he's present when you tell Foltest after you open the gate.

I'd think that its odd that after finding letters implicating Loredo(particularly the report for Thailer, I'm guessing he's from W1 since I don't remember interacting with him at all) that you're unable to tell Roche about this (a quest that got pulled?) Same with Margot's letter to Iorveth

As for the assassins, 3 are named, 1 was dead before the intro. Letho implies you'd be surprised at who was involved, so more assassins that aren't mentioned, or is that implying who's behind the whole thing...he also mentions 2 other witchers but not by name. Was Letho behind the first Foltest attack or was he the second choice of the emporer, Demavend had been dead a few months by the time you hit Flotsam. How long does it take to go from La Valette castle to Flotsam, from flotsam to vergen, from vergen to Loc Muinne? Geralt implies that Vergen is a few days walk from Flotsam. But time is somewhat ambiguous

I believe this is wrong.

I think that Demand was dead before the events in The Witcher 1

Makes sense from a story perspective but I think that the missing mention of this was a mistake by the developers

I'm assuming that is what happened. I think the writers just forgot to mention him the sotry. A plot hole, but one that doesn't really matter and can be easily fixed. On the other hand Letho and his gang could have no idea about the first Witcher that tried to kill Foltest. Maybe it's part of a bigger plot in Witcher 3 that we will be exposed too.

It's either a plot hole or a part of a bigger plot, cannot be both :)

The point here is that you are not a bard telling the story and knowing the story inside out and the plot is not protagonist centred.
There are many forces at work in the Witcher universe and just because something is not explained or does not necessary make sense straight away it does not make it an automatic plot hole.

This is like saying that major parts of Game of Thrones are a plot hole because they are not yet explained (the series of books is not yet finished) :)
