Beren and Lúthien - Changes needed

[Aiwendil]

Hi, Findegil! Excellent to see you.

True, but then what does the mention of Lúthien mean at all? It is the interest of Morgoth in Lúthien that we need to tease Beren.
I may be do not rightly understand what is the non sequitar that does trouble you.

As I see it, in the original, the logic of the passage is this:

1. Sauron mentions Boldog's mission to capture Luthien and bring her to Morgoth.
2. (It is implied that) Beren reacts visibly to this.
3. Sauron asks why he reacts thus to the thought of Luthien as Morgoth's captive.

But what we have is now:

1. Sauron mentions the skirmish on the border of Doriath, which leads him to mention Luthien.
2. (It is implied that) Beren reacts visibly.
3. Sauron asks why he should react thus to the thought of Luthien as Morgoth's captive.

But in the latter case, what Sauron says in 3 makes no sense. No one has mentioned the idea of Luthien being Morgoth's captive, so why would Sauron think that this is what Beren is reacting to?

With my last proposal, the idea I had in mind was that Beren is no longer reacting explicitly to the thought of Luthien as Morgoth's captive. Rather, he's simply visibly affected by the mention of the name Luthien, particularly coming from Sauron; and Sauron notices his reaction.
