I know, I wrote that comment and I was addressing the issue that, while it is true that there is no incest in the game at this point, there
is the build towards it, most notably the first conversation with Rachel
At the time this was written I suspect BD didn't know about Patreon's rules regarding incest and thought this level of relationship would be fine. He now knows better but this dialogue remains in the game as a tease for something that will never come; I suggested that these teases might be removed or altered.
