Even if Nale dies here, I don't think it's the end of his arc. There's pretty much been 0 payoff to the whole being a pawn of the IFCC thing. Plus that hanging Amun-Zora plot thread, though I'm not sure if the business card was just a gag or red herring.

Also, the more Tarquin rags on Nale, the more I want Nale to (briefly) win and make General Spikyhelm suffer.
