Did Bart ever get to know about Cherub or is this just a thing he’s oblivious about. If he doesn’t know about her, what do you think his reaction would be?
I honestly think Amanda Spence, her science team, the D.N.Angels themselves and Kon are the only people alive that know about Cherub's genetic origins - no one else I think knows that she is a clone created from Tana Moon and Bart Allen's DNA.
I think Bart would know that the D.N.Angels exist, but I honestly don't think Kon ever told him about Cherub sharing his DNA and she could be a genetic relative in the slightest 😂
Kon was also traumatized when Amanda attempted to kill Cherub when they were having a heart to heart and her fate was left in limbo until she reappeared years later, so I'm willing to bet it would be fair to claim that Kon didn't feel it was important to mention her because she was likely dead. But that's headcanon territory.
So no I don't think Bart ever found out and that detail is likely considered a lost detail in comics.
As for his reaction I think he'd be curious about her! She's another speedster! A clone of him that doesn't want to kill him who shares parts of his personality. He'd love to meet her I feel and establish what she is to him. OR he'd bust in on her to make damn sure she wasn't out to cause trouble for Kon again, because that's his friend thank you very fucking much. She can find her own! (maybe a bit of both)
