I really adore the idea of Danny seeming really confident and overall having a grasp on getting along in his fake identity for a new start in Gotham. Only for it to be quickly realized he's putting on a really good act and some simple investigation unravels it all (or, most of it.) Like facts are not matching up enough for his fake identity and when members of the bat family look into why this is for him they're quickly realizing that it's maybe a shotty identity because it was hastily put together but a teenager.

Faking his age enough to be a legal adult (18) so he can control over himself? Check. Faking only part of his name because he's still attached to his old life and won't admit it? Check. Leaving no paper trails and only paying in cash? Check. Refusal to participate in things that may lead to his identity or lack of one be discovered? Check. Kid also being 15/16 at most and being shit at hiding it physically, he cannot pass off as anything else than a young teenager but all documents say otherwise? Check.

Tim and Barbra quickly notice how he covered solely for himself. At least Tim was able to fake an uncle (temporarily), Danny isn't able to fake any information aside from the basics in regards to any family. It's quick to tell he's good at faking information but he's nowhere near the skill of Tim and Barbra. Once they find a single sliver of actual information on Danny and figure out who he really is, it opens a lot of questions while closing others. It also makes getting an eye and overall some semblance of control over the mysterious Danny situation they have on hand.

Like, Tim and Bruce at the very least are going to trick Danny to come into Wayne Enterprises to discuss his scholarship and hit him with "hey, we can't exactly give a scholarship to a person who doesn't exist, we know you are hiding from something by looks of our research. People don't fake new lives for the hell of it. We will however help you with whatever is going on, give you the scholarship, if you tell us what is going on." Danny of course is like, ah, no, I'm going to bail. But of course is cut off by Bruce suggesting that if he leaves without accepting their help, they'll be forced to report him and he'll be a ward of the state at best. That some investigation will happen because them finding out that Danny Fenton is considered dead before he was abled to be transferred to the care of a Vlad Masters, that is parents and friends are dead, and is overall an orphan is a big deal. ESPECIALLY when Danny Fenton is pretending to be Danny Duxo, a legal adult, and out on his own in Crime Alley and barely scraping by to be able to get to college.

They force his hand of course and accepts their help (and basically becomes a ward of Bruce Wayne). Danny convinces them that he will have Bruce acting as a guardian for him but he gets to remain at his apartment, he doesn't want to lose his tech he's working on but he's also afraid of anyone learning about his ghostliness. Does this work out? No, not for long. After a few weeks of being on his own and going out at night as a vigilante, injuries catch up with him. Jason comes by a few times a week to drop food off and comes into Danny one day bandaging some pretty nasty wounds. He brushes it off as some malfunction with some tech he's messing with but that incident causes him to be relocated to the Wayne manor so if an injury does happen, he's not alone.

And to think, none of this would be happening if he was better at faking an identity. He should have honestly asked for Technus' help for that and maybe he wouldn't be in this mess. This is all just surrounding his human identity too! Oh my god, the bats are going to freak when they find out Danny is way more than human and also a vigilante!
