Just out of curiosity, but in almost all of the doggo scenes, David was more or less present, for example
With Vera I was only observing but I also had a small participation
The same thing with mine, except that in this one he was only observing as far as his curiosity went
With Martha it is the opposite, he does not know or even know that Martha had sex with Doggo since he was not even an observer, it is not yet known if he will one day know or it will remain a secret between Martha and Doggo.
now with lucy it is not yet known
