I got into the lore through the Dark Age books, but this past year I got the chance to read the "Blood of Kerensky" trilogy for the first time. One thing that stuck out to me was how the Clan characters talked to each other.
In the BoK novels, bloodnamed characters refer to each other as "grandmother" (Rianna to Natasha), "uncle" (The Ward Bloodhouse leader about a previous Khan), and "children" (The Smoke Jaguar commander on Wolcott about the sibkos bred from his DNA). It is clear from these novels that bloodnamed warriors, if they live long enough actually do get to encounter their descendants, and use the correct terminology that an Inner Sphere person would be familiar with.
Fast forward to the Dark Age novels and that style of communication seems to have fallen out of favor. Clan characters are constantly uncomfortable around such terms, and they almost never gets used.
I found this interesting, and was wondering what the general consensus on why this change occurred, or if it occurred earlier in the CBT novels that I haven't read. I would assume one reason for the change is that, 100 years after the invasion, Clan characters are far more spread out, bloodnames are less common, and warriors are just less likely to encounter their descendants/ancestors. Whereas in Clan space due to the proximity it was far more likely.
