#He's baffled about the entire thing just as much as Baxter tbh....

[cyberwhumper]

How much of Whiskey’s memory is kept intact when he dies? Like, does he know why Baxter is torturing him? Or is that a memory only the previous Whiskey had?

I touched a bit on this here!

His memory is the same up to a certain point, which is unknown to Baxter and his people at this time. Memories past this specific point are not retained and are lost when Whiskey is killed.

He doesn't know why Baxter is torturing him. From the current Whiskey's perspective one day his boss just suddenly flipped his shit and kidnapped him, and is now convinced that he knows things he doesn't.
