Awesome, like, Danny would 100% be angry/annoyed that he is british (technically)
Alfred has suspicions. Alfred is also annoyed that his DNA got stolen by a drunk couple, how did he missed that???
Bruce and the kids can’t even imagine it could be Alfred, probably because most of them see Alfred as the most competent human, how could he get his DNA stolen and used without anyone knowing???
Danny moved to Gotham to complete his university studies. They had great programs and scholarships. Unfortunately this put him on the radar of the Waynes (the ones in charge of his scholarship), who became extremely paranoid when they noticed the black hair and blue eyes.
They collected a DNA sample (ignoring Barbara's protests that not everyone with that hair and eye color was a clone), his sample was found to be corrupted but tested positive for someone registered in the Batcomputer. It just didn't recognize who.
Of course, they suspected the coincidence was because of Bruce. Danny was unaware of any of this and continued with his studies. Traveling to the Realms from time to time. None of the bats were able to catch him after collecting the sample, it seemed that the boy was more paranoid than they were.
Ironically, he wasn't a clone of any of the Waynes. He was a clone of Alfred Pennyworth, whose sample had been collected during his time in the British service, and later stolen by the Fentons (out of curiosity, rather than crime).
Not that they were going to find that out anytime soon, but the fact that the halfa had more common sense than all of them should have given them a clue. Besides, he did know how to communicate.
