If you ask Booth about people with red eyes first, you can't later access his dialog option to ask what he thinks of the TMD once it is formed. The generic topic about Red Devils shouldn't prevent the more specific question about quest consequences that unlocks if you never talk to him about Red Devils.

This is the kind of thing that feels super trivial to report, but it is a bug that does block content (one optional gossip style dialog response) and it is easily fixed.

[0009A971] Scene DialogueCydonia_Booth_Top_RedDevils02 has a third condition to check GetStageDone equal to 0.0 for DialogueCydonia[Quest 0024AFED] Quest Stage 2301 "Booth mentioned the Red Devils".

I suggest removing this condition, since neither topic should block the other. They both involve the Red Devils, but one is a question about them as a group from the war up until pre-TMD, and the later topic is asking Booth about his opinion of the TMD overall and the Red Devil's involvement post-TMD.

Copying the condition entry results in this if it helps: [00] Starfield.esm \ [65] Quest \ [2547] Children of 0024AFED \ [1810] DialogueCydonia_Booth_Top_RedDevils02 [SCEN:0009A971] \ [10] Conditions \ [2] Condition \ [0] CTDA - CTDA
