And what is the secret behind the sudden rash of pregnancies on Paradise Island?
I'm going to go ahead and put my money on the answer being that Bruce realized the potential of Damien, but viewed Talia as weak genetic stock. This is why he's faking his death, taking time to knock up Themyscria's populace. And before anyone argues by asking what use Amazon's would have with a man, I submit that among Batman's skills, he is the world's best lesbian.
