Obviously BIG spoilers below..




I wonder, especially in some particular endings what Letho did and why. We learn that He had worked for the empire because 1, they had captured him, 2, they promised to reestablish the viper school (I wonder how would they do that, but anyway)

In both path (Iorveth-Roche) if we don't go after Triss Then Letho will be presented as a prisoner who will falsly confess that He was hired by the sorceresses.
At this point Is He still working for the empire? Is it part of their plan? Probably, but I don't see why he would do this.. He seemed to be a smarter guy than let himself willingly exposed as kingslayer. But If He doesn't work for them anymore (He got betrayed) then why would He lie defending the Empire?
In any case after entering the Dragon He goes to save Triss from a Nilfgaard dungeon.. Is that mean He turns against his former employee giving up his possible reward? (and when did He find the time to manipulate Sile's stuff )

Eh, many questions..

He still working for Nilfs, he need to shift his blame to sorceresses who can oppose Nilfgaard
I am not sure he was "captured" by them. After shit hit the fan he tried to make peace with Geralt so he rescued Triss

He messed with diamond parts in Flotsam, remember he captured Triss in Sile`s room

Yeah, Letho was framing The Lodge for the assassinations, though they wanted to kill at least one king anyway so they weren't innocent at all.

The north is in chaos, and Nilfgaard troops are on the move, thus Letho's job is complete. He considers Geralt a friend, so he goes to resolve matters with him. Most likely, the Nilfgaard delegation has fled, so freeing Triss is not an act of aggression toward them, but an act of mercy and a token of friendship to Geralt.

It's possible that it was their plan to frame the lodge this way, but I don't think it1s a smart thing to do by Letho. This way He can expect the the empire will betray and kill him just to keep their secrets and even if He escapes He will be wanted everywhere as an assassin of kings.
And did He saved Triss just to make peace with Geralt and giving up everything He fought for ( the viper school) seems unlikely.

edit, yeah, it's possible that The Nilfgarrds have left so Letho didn't have to kill them..

Letho said that he accepted the Empire's mission because he promised to restore the Viper school. If you had paid attention to what he said, you'd know that witchers were outcasts in the Empire, and they were banned from most major cities. This was obviously due to the Emperor, which means what the Emperor can take, he can also grant.

Restoring the school of the Viper would be easier for the Emperor than turning the northern kingdoms into chaos, which is why he enlisted Letho, who had a reason, drive, and ambition to see the plan through the end.

Letho said during the final conversation that he had no plan to blame the Lodge from the start, as he didn't even know about them initially. He got the idea after Sile de Tansarville asked him to kill Demavend.

As for the Empire, it seems they had no reason to betray him. The fact that Shilard captures Triss and makes her spill the beans means knew of the plan, which is why he appeared in Foltest's camp, in Henselt's camp, and later at Loc Muinne. He was there to help facilitate things, and ensure everything goes well. For the same reason, he's presented as a witness in Loc Muinne and lies about the Lodge being behind it, as the restoration of the Conclave would forfeit everything done up to that point.

With regards to Triss, he didn't protect her from assailants because he was afraid of Geralt, but because he always said that Geralt wasn't his enemy. He didn't want to kill the White Wolf possibly because of respect for him, or maybe some lingering feeling of debt. He didn't need another enemy, he just wanted to go his own way.

He didn't "go" against the Nilfgaardians by "saving" Triss, which was by this point, expendable. His mission had been accomplished once Loc Muinne (and the would-be Conclave) went up in flames, reinforced by the fact that the Emperor already had his army crossing the river separating the Empire from the Northern Kingdoms.

Cue applause.

When you side with Iorveth and speak with him after the final fight he says something along the lines of no Nilfgardian dared to stop Letho when he "rescued" Triss. I'd assume Shilard and Renault? fled at the first sight of the dragon. Triss's death would have been convenient, but her escape probably meant nothing to them, her purpose was to simply sit in the dungeons as the nilfgaardians fabricated some testimony to turn the northern kings against the magic users.

The main issue I had with Letho was that his entire motivation for killing the kings was to simply get a witcher (school?) in Nilfgaard.... And does anyone actually believe the emperor will follow through with that promise... especially considering you have the opportunity to kill Letho.

The school was the only reason he states outright, but the admiration he shows for the emperor at the end of the game seems to imply that he was doing it more or less as a favor for someone he respected. That's the impression I got, at least.

This reminded me of

"Emhyr var Emreis, spice merchant" -Roche

But yeah, i also remembered Letho saying something about how the Northern Kingdoms' royalty only comes up to about his knee armor or smth (i forgot the exact phrase).

I took that line as more of a knock on the Northern Monarchs than praise for the Emperor, but that does make sense.

We saw how much the empire value their own men's life.. not at all. they killed that sorceress, the ambassador (or did He survive the shot? looked that way). i'm pretty sure they would kill Letho after He made his confession. first they won't leave witnesses, second: war is not a crime, more like a virtue in the withcer's world, but regicide is a crime no matter what. So after they presented the assassin they would kill him just to show the word that they punish the murderer and no one will connect them to Letho. So I think it was not smart from Letho going into this game.

They killed the sorceress because she was part of the Lodge, whose purpose was (among others), the stability of the Northern Kingdoms. Killing her is fair game.

As for killing Letho, and worrying about witnesses, it would be pointless anyway, since the damage to the North is done.

Setting aside this whole pointless Letho talk (since everything is already explained in the game), I'm curious what will happen to Francesca Findabair, the Sorceress that rules Dol Blathanna (the elven state that the Emperor founded on a whim), as she was part of the Lodge of Sorceresses as well.
