Sometimes, some dialogue that appears may be out of the game's story context. Here's a thread to compile them for reference.
Spoiler warning: Read at your own risk.
[1] I recall that Gene only mentions the news about Edmund Knight AFTER certain Oligarch quests have been finished, and that Gunnar says that the news about Edmund Knight has not yet gone public before giving the player the task of seeking out the Acid Hunters. I believe the news only goes public AFTER the research facility events have concluded.
[2] Arlene mentions that Gorsky's gathering up his squad even after Gorsky has departed to Core City.
After Lenox's Questline is completed, she still mentions the rumor that Mordre's been acquiring cigars.
