Hi Garak3D.
You've left us in suspense with this new update, especially in the last image hahaha. And the details are incredible (I don't know how you manage to include all of Batman's body hair).
Good transition between Diana and Martha. I imagined there would be some similarity. It reminds me of a scene from "Justice League" animated where WW and Batman talk about having normal relationships like everyone else, and Batman says, among other inconveniences, that he's a "rich kid with issues, lots of issues" hahaha
However, this is the second time Batman goes from present-day Gotham to his childhood past with Martha. Could he have been contaminated by the toxin from the two mothers and their children during the fight? Only time will tell.
It's clear from the last few pages that Martha isn't still alive (at least as far as we know). This makes me imagine a possible scene, which I don't know if you have in mind, although I think it's a bit murky. Martha and Thomas Wayne die the same way originally, but Martha lives a couple of minutes longer than Thomas, and before leaving, she asks Bruce to cum in her mouth so she can leave with the taste and smell of her son's semen with her (although that would leave Bruce exposed when the bodies are analyzed, but it could be used as a way to reveal his past with his mother in present-day Gotham).
As for Harley, as you say, it remains to be seen who she'll sleep with. I'd like it to be Batman. Harley is seeing all this sexual chaos, she's getting horny and she wants to have her share of the action with her beloved Joker. But Joker has more important things to attend to and he leaves her unattended. This could be exploited by Batman or any of his allies to extract information from her. Like: Harley, if you tell me what the Joker's plans are, I'll offer you this "great toy" to play with hahaha.
Greetings
