Something I've been wondering about in regards to the cu secret superhero au: do Ben and Edith still have Alexandra later down the line? And if so, does her dad tell her about his superhero alter-ego or does she have to find out on her own somehow?
They would have Alexandra (both her and her brother) though it would be very unexpected for Benjamin since he was sure the whole ‘looks human but not biologically compatible’ would be in play. He’d also have less insecurities over being a dad compared to his canon self.
He would be honest with her about his time as a superhero since he’s more open to trusting more people by this point and he wants to have a good relationship with her (especially since his adopted dad was a good father figure).
Now as for the powers… if she did, Alexandra would likely inherit his super strength and durability specifically (her brother would get flying). (However I set up this prophecy in a past post where CU would undergo a death similar to the books, except it would be just a loss of powers and thus the ‘death’ is metaphorical (and he doesn’t actually die). So there’s the question of if she’d still gain those powers or not.)
On the other hand if he still had them, then there would be more concern in having Alexandra keep his identity secret (as well as any potential powers she would have) since she would be the next in line in the Underpantyworld Royal Family after her Dad.
