Tim made several attempts at bringing up Danny's more... peculiar qualities without tipping the boy off. Tim still wanted Danny to come to him about it, to tell him in his own time. (And Tim really didn't want to bring the other bats into this. Danny wasn't a threat, and he knows how Bruce would react if Tim brought up how Danny might be an unknown species. No, Tim would figure this out on his own. That way when Tim does eventually tell Danny he's Red Robin, he has everything planned out and he has the highest chance of making sure Danny and his family get along.)
However, Tim was also itching for answers. He didn't know of any aliens that purred, or if they did, they certainly didn't do so in front of him. Besides that, Danny clearly wasn't Kryptonian, Tamaranean, Martian, or any other alien that Tim was familiar with. Which means Danny had to be something else entirely.
Considering there haven't been any clear major cultural differences, Danny probably was raised on earth. He might be a case similar to Clark, and in that case he might not even realize what exactly he was, but Tim found it hard to believe that Danny didn't know he wasn't human.
Even though Danny wasn't the...smartest, that didn't change the widespread information about aliens on earth, or the fact that Danny himself was obsessed with information about space. Looking back on it, Danny being an alien might be the entire reason why Danny loves space so much to begin with.
So, attempt number one: Declare that aliens are super cool and how he would love to meet more of them.
At first, this didn't seem to be like a bad idea. In fact, Danny perked up in the cute way that he does any time something interest him. A sparkle in his eyes and a large grin on his lips, he eagerly divulged into a conversation with Tim about aliens and space in general. Which eventually involved into Danny talking about how Martian Manhunter was his favorite hero of all time.
Tim didn't have the heart to ruin Danny's fun, even when he could tell his boyfriend sorely missed the hint he was dropping. It wasn't an entire waste. After all, seeing Danny talk about something that he was so passionate about sent Tim's heart ablaze and kept a warmth throughout his body. Right then, plan b.
Attempt number two was honestly a little more desperate than the first, but Tim had thought for sure that it would work. Maybe Danny didn't realize that he wasn't human! So Tim being Tim, he created a fake brochure on "How To Recognize If You're An Alien: 101", and coincidentally left it to where his boyfriend could find. And while Danny did read it, it just brought up another conversation about space and the stars. And while Tim loved hearing his boyfriend talk about his interests, it doesn't change the fact that this hadn't exactly been what he was after.
Alright, fine. Tim could work with this. He'd just get Danny to pur again and bring it up then! It would be perfectly natural, not out of nowhere, and he could pretend that he hadn't been cataloging his boyfriends peculiarities!
So, attempt number three had been a go! Only, Tim couldn't get Danny to pur again like he had that night. It didn't matter how much he cuddled the man, or ran his fingers through his hair in an attempt to get the boy to relax, Danny never did end up purring like he had that night.
Not that Tim was particularly frustrated with attempt number three. It was the one he had enjoyed the most by far, and even if he hadn't gotten the results that he wanted, it doesn't change the fact that the moments spent curled up against Danny had been utter bliss.
(And if this was because Tim was a useless bi-disaster, no he wasn't Jason, you can shut up! It's for science, and no, he will not be elaborating!)
At this point, Tim had to consider that his boyfriend hadn't actually purred. That maybe it was a sleep deprived hallucination. Except, Tim had been getting better sleep ever since he started dating Danny, for the boy always made sure to drag Tim off to bed whenever Tim got particularly bad about not sleeping. (Tim could never find it in him to turn Danny down, not when he stared at him with those artic blue eyes that at times seemed to glow.)
But Tim had never been one to let things go. He was certain that his boyfriend had actually purred! And Tim could admit that maybe Danny was oblivious enough to not notice that he was human. (Danny was the first person that made Tim seriously consider if he was into idiot men that at times had a hard time functioning in everyday society. Shamefully, he had to admit that he very much so was attracted to that.)
(Unbeknownst to Tim, privately Danny thought Tim was the one that had a horrible time with basic function. The man didn't even know how to use a washing machine until Danny showed him how! Or a toaster. Actually, Danny refused to show Tim how a toaster worked. Toast was evil and the food deserved to die.)
So, attempt number four. Actually, Tim had yet to attempt it. Rather, it had just been an idea. If Danny didn't think he was an alien, then he probably thought he was a meta-human. And if he did, that doesn't change the fact that he still didn't feel comfortable enough sharing this information with Tim. But if Tim was to show him his own form of extreme trust, that might just change things.
Which was why Tim considered telling Danny that he was Red Robin. Tim really wanted to introduce Danny to his family, properly. Sure, Danny knew of them, and even personally knew some, but it doesn't change the fact that a big part of his family was comprised of their vigilante selves. That a large part of Tim was comprised of his vigilante persona, and he wanted to trust Danny with it. And hopefully, if Tim tells him this secret, it would make Tim comfortable enough to tell Tim about whatever the hell Danny happens to think he is.
Only, Tim never got the chance to make this decision himself. Not when he crash landed into his boyfriend's apartment, heavily injured, and proceeded to pass out.
The next time he whole up, he was dressed, changed (probably because the only was to dress his injury was to remove his armor), and in his boyfriend's bed, with said boyfriend purring next to him.
Tim's mask had been left alone, but Tim was certain that his boyfriend would recognize the scars he had, there was no way that Danny was that oblivious. Add in the fact that there was also no way that Danny was not going to meet the rest of the Bats as vigilantes, as Tim was sure that Barbara had someone check on Tim the moment he failed to report back. So there was absolutely no way that cat was going back into the bag. Sighing to himself, Tim left sleep consume him, deciding he could deal with it in the morning.
"So, you're Red Robin?" Danny asked, staring at Tim from across the couch, his expression neutral, not giving anything away.
"Yep." Was Tim's oh-so-intelligent response.
"And you thought it was a good idea to come to me while injured instead of going to someone that you knew could help you? As touched that I am that you trusted me, you could have died Tim! I'm hardly a medical professional." Danny ranted, and a stab of pain went through Tim at Danny's expression. The boy clearly distraught over the idea that he wouldn't have been able to help Tim. That Tim might have died last night.
"I know... it's just, I've been thinking about telling you for the past few days. So, I think my body just lead me here." Tim explained, and yet Danny's expression didn't faulter.
"I love you too, but I'm still mad at you." Danny huffed. Tim was quiet for a few moments, deciding now was a good a time as any.
"So, when were you going to tell me you were a meta-human?" Tim asked. Danny blinked at him, his expression morphing into confusion.
"What are you talking about, Tim?" Danny replied, looking genuinely lost. And while Tim knew Danny wasn't always the smartest, there was absolutely no way Danny failed to notice he wasn't a normal human.
"Danny, you always run at a lower body-temperature. You've managed to sneak up on me and several of my family members, and we're trained vigilantes. You have enhanced senses, don't bother lying, I know for a fact that you do. And I'm almost positive that you have enhanced strength. That isn't even talking about how your eyes glow in the dark, or the fact that I caught you purring. Literally last night." Tim listed, watching Danny's expression go blank. The boy looking thoughtful for a moment, biting his lip in a way that almost made Tim want to drop the conversation entirely and kiss the boy senseless. Almost.
"I'm not a meta-human." Danny began.
"Danny--" Tim sighed, not wanting his boyfriend to lie to him when he just revealed the biggest secret he had. Besides his missing spleen.
"I'm not an alien either." Danny snorted, seeming to have not realized what Tim was trying to get at these past few weeks. "But I'm also not entirely human either. I'm something else."
Tim blinked at his boyfriend. Confused. What was Danny talking about?
"Danny, what are you talking about? You can only be meta-human or an alien. There isn't anything else that you could possibly be." Tim pointed out. Maybe his boyfriend was just confused?
But Danny just gave him a wry smirk, and in a flash of light, Tim was staring at someone else entirely. Or at least, it seemed like he was for a moment.
Sitting in the place of his boyfriend, was well, his boyfriend if his boyfriend looked entirely different. Had had bluish-greenish tinted skin and toxic green eyes that reminded Tim of Lazarus waters. His snow-white hair moved and swayed as if the wind was blowing through it harshly. Pointed ears seemed to wiggly mockingly at Tim as Danny gave him a too-wide grin that showed off a pair of sharp canines.
"Suprise." Danny spoke, making jazz hands. "Your boyfriend's a ghost."
Tim blinked and then he blinked again.
Tim lied earlier. This had to be what took the cake. And considering Danny's insufferable little grin, he knew it too. God, his boyfriend was such a little sh*t.
Tim didn't know what it said about him when this fact just made him want to lock lips with Danny even more. Instead of addressing that, and the fact that deep down, he truly was a useless bi-disaster that had a hard time focusing on anything when his boyfriend looked at him like that, Tim instead landed on--
