Tim stared at the unconscious teen. He was found, heavily injured on the side of a road and police ruled it a hit-and-run... even though the doctors said his injuries were more aligned with being very close to an explosion than being hit by a car, but that's the only evidence of it. Not only that, but he's been unconscious since he was picked up, so they weren't getting any explanations from him. The hospital ran his DNA as a last-ditch effort to find out where he'd come from - and Tim was the only living relative they could contact.
There were side-eyes and gossip surrounding this whole situation. John Doe still only partially matched with Jack and Tim, there was no blood shared with Janet, and no match to anyone else in the hospital database - or the Bat-database, yet, but it was big enough it could take weeks to go through the entire library. And looking at him... Yeah, Tim could see the resemblance.
Tim could 100% buy that this John Doe was his brother. They shared the Drake babyface, if their age estimates were correct, he was about two years younger than Tim. But accepting that meant accepting that his dad... Tim knows his dad would never have cheated on his mom, but this kid had to have come from -
A whimper came from the kid in the hospital bed, Tim jumped up to watch as he finally woke up after a three day coma. "Hey, kid -"
"Gah!" The kid started panicking and tried to pull the IV out of his hand.
Tim grabbed his hand to stop him, "Hang on! It's just fluids to keep you hydrated. you've been out for like, three days."
The kid looked up at Tim in confusion. His voice was rough around the words, "Three days?"
"Yeah." Tim said and let go now that he seemed calm. "What's your name?"
The kid stared at him with eyes slowly growing with worry, "I'm Danny."
Fear flashed across his face and Danny ducked his head in shame. "I... um..."
"It's alright if you don't remember right away." Tim said and Danny looked back up at him. "The police say you got hit by a truck. Do you remember that?"
Danny looked ... hopeful? for some reason? "No, I feel like I got hit by a truck but I don't remember it."
"How about how old you are?"
"Uh..." Danny seemed to need to actually think about it, "I just turned fourteen, I think."
"Oh, I see." Tim said, though, given what the doctors said, Danny should be closer to 16. "I'll let the nurses know. Is there anything else? How much pain are you in, do you need more painkillers?"
Danny blinked at him, "Do I know you? You look really familiar."
Tim tried to smile, "Not really, this is our first time meeting."
"Okay. It was nice to meet you- um?"
"Tim, Timothy Drake." He said and extended his hand to Danny. "It's nice to meet you too, Danny."
Tim turned to leave, but Danny got his attention again, "Wait, Tim, if you're not a nurse or whatever, why are you here?"
Tim was going to wait until after the nurses gave Danny a check-up and make sure he's actually fine. But, Danny did ask, so, "Well, according to our DNA, I'm your half-brother."
"Huh..." Danny said and stared confused at Tim for what felt like several minutes before saying. "I always wanted a brother. Cool."
Tim nodded and smiled then left to get the nurse's attention. He's not entirely sure Danny understood what was going on - and they should probably check his brain for damage.
