As best as I can determine, Robin was seventeen when the Teen Titans were formed. Raven was fourteen. I haven't found a record for the ages of the other Titans, so I've created ages that seemed right.
Season Six: Burning Bright
Titans Divided
In a once-empty warehouse in Jump City's underutilized industrial district, a small wealth of monitors and computers was crowded into the small security booth that had once held a comparatively primitive closed-circuit camera array. The floor of the warehouse was covered with several models of the robotic shapeshifter created thanks to cribbing from the work of several scientists.
The robot had been perfectly designed to fight the Titans to exhaustion, but Slade had forgotten a variable. Something in their worldwide adventures had bent Robin's pride to the extent that the boy had called for help. That changed things, and it changed them in a way that Slade had not anticipated.
It was almost time to strike against the Titans in the one way guaranteed to hurt them, and to discount the possibility of outside help. He only needed a few more resources. Every last component of his new creation was easily obtained by a motivated man of some means.
After a full week with no battles to fight, and with no signs of Slade, the Titans had little to do but think about the important question: were they going to be the Teen Titans forever?
Robin was seventeen when the Teen Titans had formed, and at twenty, he wasn't a teenager anymore. Raven was only seventeen after three years with the Titans, but not one Titan was surprised to learn that she had already earned her G.E.D. thanks to online coursework and the social security card that had appeared in her name just weeks after the Teen Titans were formed.
"Wait, when did you pick up a diploma?" Cyborg asked, leaning forward far enough that he nearly toppled off of the couch. Starfire was sitting primly in midair, legs crossed, and Raven was perched on the armrest with an open book disregarded in her lap. That was the only reason all five of them could sit comfortably in the once-large common room. "We would've held a graduation party for you."
"Four months ago," Raven admitted. "I'm not exactly up for regular parties, and my seventeenth birthday party was enough. I had to do something when we had too many people here." In contrast to her very dramatic sixteenth birthday, her seventeenth had passed with a small cake, one candle, and a short-lived paper party hat. Raven had complied with the headgear for a grand total of two minutes on the combined coaxing of both Starfire and Beast Boy. The team had wisely decided against a tiara.
"I had mine before I turned nineteen." Robin didn't know what his parents would have wanted, or if they would have been happy that he earned one degree, but Bruce Wayne would not be satisfied without a college education. "I'm waitlisted for Hudson University. I know we haven't talked about it, but I feel like we've fought enough battles."
"Friend Robin, you have not told us!" Starfire's usual cheer was subdued. "I had not realized that our time might come to an end so soon, and I have not yet finished my General Education Development. The mathematics are most diverting, as well as the sections regarding proper grammar, but studies of the social variety are quite challenging. I had not realized that America had such a long history, or that so much of it was unhappy."
"You're making good progress, Star, and there are a lot of good parts the textbooks don't talk about." Cyborg had been tutoring her in history and chemistry; Tamaran had a much different view about how the world worked, and she had drawn several diagrams on the whiteboard he'd bought. When he wasn't teaching Starfire, he was teaching Beast Boy physics and calculus. Calculus was beyond the scope of the G.E.D. but Beast Boy's attention span was pretty incredible when he put his mind to it. Unfortunately, Beast Boy rarely put his mind to it. "I passed it a while ago," Cyborg continued, "but my dad would not have been happy if I didn't have that much done by eighteen. I've thought about applying for college sometime. Engineering is a pretty obvious fit."
"You'd be great at that," Robin said thoughtfully. "It's been a while since Batman and I have really gotten along, but a mutual friend is really pushing that it's past time we talked this over. I'm his heir, legally, so I'll probably go into business."
"I'm thinking about veterinary medicine, probably at a zoo," Beast Boy said to no one's great surprise. "Exotics are pretty easy when you can literally speak the language."
"I am unsure which course of education that I would like to pursue, or if I would choose to attend a university where I would be an object of much attention," Starfire said slowly. "Truly, it will be difficult to blend in when the differences between the other students and I are so obvious."
"I can take care of that," Cyborg promised. "I've been playing with my old hologram rings for a while. It was going to be a surprise, but now is as good of a time as any. I've made one for everybody, in case we wanted to go on a field trip where nobody knew our codenames. I want to go to college under my real name."
"You've been pretty quiet, Raven." At Robin's comment, the team turned to look at their stoic friend. "Are you planning on applying? The due dates for all the colleges aren't coming up for a few months yet, and it might be time for all of us. Starfire has an alias, too, and I think all of us could use the break."
"I think I want to have a look at Gotham, and look up where my mother lived. That is, if you can talk your guardian around. He isn't very fond of magic, or demons." Raven had never mentioned her misadventure in Gotham, traveling where her mother had grown up, and finding the then-abandoned building where a cult had performed the ritual that brought Trigon to earth in the form of a human man. "He wasn't exactly diplomatic in asking me to leave his city. It turned out that an associate of his knew something about the prophecy. I wanted to get as far away from him as possible, and tickets to San Francisco were cheap that week. I was tired of big cities and big crowds, so I came to Jump City on the bus." The speech was one of the longest that Raven had ever made, and not one Titan wanted to interrupt.
"I am most glad that you did so," Starfire said when it was clear that Raven was finished. "Our team would not have been complete without you, or without any one of us. I lost my parents long ago, and my sister has long acted as if we are not family. You all are my family, now."
"You're more family than the Doom Patrol ever was." Beast Boy was more and more capable of seriousness, and ever since he had led reinforcements against the Brotherhood of Evil, the team had treated him accordingly. "So—um—thanks."
"Maybe we all can go to Gotham. Hudson University is... well..." Robin looked embarrassed, a rare sight. "It's a little past the income we've all built up from Jump City, but Gotham University has really good scholarships.
"I have a few connections that would be willing to give all of us great recommendations for community service. Batman's come a long way when it comes to backgrounds, Raven, and we fought about that for most a year. He actually conceded an argument, and I can tell you exactly how many times I've won. That's twice." Robin did not look inclined to elaborate.
"Stubborn guy," Cyborg said, already adjusting his plans for the hologram rings. "I can deal with Gotham. My dad and I are getting along good now, but both of us could use a little more space. He was always the scientist that didn't know what to do with a kid, and when my mom died, I almost did. Dad was the one that put in all the hardware, and all of it was his experiment. Both of us could barely talk without missing Mom, so we stopped talking."
Starfire floated close enough to take his hand. "I know it is never quite the same, but I sympathize. I do believe that all of us but Raven have lost our mothers."
"We were never exactly close to start with." Raven's tone was wry, and bordered on dismissive, but she didn't look away from the four of them. "She ran away from home when she was seventeen. A cult that worshiped Trigon took her in, and when she was pregnant by Trigon in human form, she thought that her parents would get hurt if she went home. Azar and the rest of the monks took her in when she didn't have anywhere else to go, and by the time I was born, she was a different person."
"Have you been back to Azarath, friend Raven?" Starfire asked, hope clear in her voice.
Raven's expression closed entirely. She hadn't done that to any of them since her sixteenth birthday. "I think all of them died. Trigon went there, first, and the protections weren't enough. I tried to go back, to tell them that the prophecy was wrong, and the only thing left was a dove." Her voice was entirely dull, but they knew better than to assume she wasn't hurting. "I'll apply tomorrow. I don't want to start on my own, and all of us could use a change in scenery."
"I am most sorry to hear such sad tidings." Starfire knew better than to attempt embracing her friend when Raven's control was already tested. Her friend still preferred to handle her sadness alone.
No one said a word for a full minute after Raven vanished in a flash of black edged in white.
"I think we're making her favorites for dinner tonight, even if she won't come down. We'll give her a few hours on her own," Cyborg said, sounding confident enough that none of them imagined protesting. "Beast Boy, you're on dinner delivery if she won't come down."
Beast Boy's voice had changed two months before, after causing several embarrassing moments when attempting to order a criminal to stop. His voice still squeaked when "me?" popped out.
"You talked her down after Malchior, she talked you down after Beast. It's your thing," Cyborg said easily. Beast Boy's shell-shocked look only confirmed that this wasn't the time to talk about Beast Boy's yearlong interest in their moody teammate. The growing attention was subtle, and subtle enough that even Beast Boy might not notice yet, but a guy always knew when his best friend was halfway up to the moon over a girl.
"It would be of great comfort to her," Starfire agreed. "I will look into this Gotham University to see what programs are offered. Raven has been most reticent thus far, but I believe that she will be interested in literature. She has taught me much about Earth novels, and introduced me to several that I enjoy very much."
"I think it's research-time for all of us." Robin glanced toward Raven's room, but then looked to the still-shocked shifter. "I know Gotham University has a surprisingly good animal sciences department, for an city-based university. I don't know her really well, but a costumed friend of mine is a freshman there."
"They have a few patents on mechanized prosthetics, too," Cyborg added. "Anybody else in for the ride? We all need some time without a whole city to look after, I think, and Gotham's in good hands."
"I'm convinced," Beast Boy said. "We're still a team."
They might have said more along those lines if the alarm hadn't blared for the first time in a week.
Moments later, a dry-eyed Raven appeared in the common room with no signs that she had retreated away from the rest of them. "I can get us there fastest, if none of you mind traveling by portal."
Beast Boy still regretted his blurted comment about the relative creepiness of traveling via the Raven Express. He knew she was a little self-conscious about the sliding sensation, but he knew he'd made it a little better. Comparing it to apparition in the Harry Potter books had helped, and she even had free points to feign shock that he had read one book, let alone seven. Sometimes, he actually understood Raven's carefully hidden sense of humor.
Robin answered for the team. "Let's go."
By the time they reached the Jump City Credit Union, the deed was already done. Slade was far more professional at bank robberies when he had the motivation, and the motive was clear when a shaken bank manager showed them the empty vault. There was a small placard that said only "The TRuce is over," with a distinct circle around the R.
No one knew what to say, seeing their leader's symbol in Slade's note, but Beast Boy broke the silence.
"Again?" Beast Boy said indignantly. "I mean, no offense, dude, but it's getting a little old that Slade's always interested in you or Raven."
Raven's brow rose. "Do you really want Slade interested in you?"
"Well, no, but it's the principle of the thing." Beast Boy's emphatic gestures seemed to be taking the place of logic as well as serving as a distraction from a new subtext, but no one minded. Robin and Cyborg were taking the time to scan the emptied vault before Beast Boy tried several smell-sensitive morphs, one right after the other. "No good. He laid down false scents, and I already know he went straight from here into a waiting car. I got that much on the way in."
"We should split up," Robin said. "There's no way we cover all of Jump City together. It's time that we stopped him once and for all, if we can find a prison that will hold him."
"I'm with Raven." Cyborg spoke up before Robin could assign teams. "We need to split the trackers, and the pair of us have worked on this before. BB's on the other team."
"I can search from the air alone." Starfire's words were calm and left no room for opposition. "Slade does not have the same obsession with my person. It will be best that Raven and Robin do not stay together, as they would be too tempting for Slade to pursue."
"Deal," Beast Boy said before Robin could protest. "I can track him when we get closer. He might think to block his scent out, again, but I can follow the false trail that he uses. I just smell for the place without a scent."
Robin would not have chosen Beast Boy as his partner, but he couldn't back out now without angering his entire team. "Let's move out." He had planned to work with Starfire, like they usually did, and he didn't like that she would be alone in the air. He and Beast Boy rarely had anything to say to each other that wasn't about who was making dinner. When they first met, Beast Boy's hero-worship had been off-putting even as it made impossible for Robin to talk to him. Then it had been jealousy over the motorcycle, disgust with Robin's eating habits, anger about Terra, depression about Terra, and most recently, hope that Terra was alive after all.
Surprisingly, Beast Boy didn't say much. He regularly changed forms to track the lack of scent, but his focus was impressive. Sometimes, Robin forgot that Beast Boy had led the team that pulled everybody's bacon out of the fire.
Robin was the one to break the silence. "Do you think we're getting close?"
"I'm guessing he headed for a warehouse again, it seems like his usual deal," Beast Boy replied without hesitation. "I picked up a car that drove through here recently, and the non-scent coming out of it. We're on the right path, and we're not far behind him."
"Look, Beast Boy, I really should… I feel like I've been unfair to you."
Beast Boy's left ear twitched. "It's fine," he said. "Really, Robin, no hard feelings. Let's focus on the case."
The role reversal left Robin stunned, but he had to agree. Beast Boy was the one to lead them to the correct warehouse, and to find the open door with minimal signs of traffic. That was their first mistake. They assumed that taking the unused door would be novel thinking, not the most predictable move that they could make. Robin had entered first, but that didn't matter. As soon as Beast Boy was framed in the open doorway, several tranquilizer-like rounds fired into his torso, easily penetrating the spandex blend of his costume.
Every one of the four darts was filled with a noxious green fluid that rapidly disappeared into his teammate's chest.
Beast Boy fell to the ground before curling in on himself just inside the doorway of the warehouse. He didn't seem capable of moving any further. "You should get out," Beast Boy gasped. "Call Raven, she knew what to do last time."
"Beast Boy, what..."
"Can't control this," Beast Boy gritted out. "Turning into the beast again, and I don't think he liked you last time. He might remember."
Robin took several steps back, but he wasn't going to leave his teammate this time. "Titans come in," Robin said into the com as he scanned the warehouse for additional threats. "I could use some help at the warehouse six east and four north from the Murray Recycling Center."
"What is the sitch?" Starfire asked immediately, her delight in asking the question quite obvious. "It is a reference to that most diverting documentary!"
"The sitch? Ah…" Robin glanced at Beast Boy, averting his eyes for his teammate's sake when his uniform began to tear away. "I think Beast Boy's about to tear my throat out, literally, but I'm not leaving him with Slade in the area."
"Uh, Beast Boy?" Cyborg said incredulously. "Remember that we like Robin."
"I don't think he can hear you, Cy, or if he can, he's not going to take it in. I don't think his were-beast form is so big on verbal comprehension." Robin glanced again toward the corner, bracing himself when he saw that the change was nearly complete. He wouldn't let Beast Boy end up as some toy of Slade's. "I would try to get him out of here, but he won't fit through the only door we've tried. Slade had a trap set up that dosed Beast Boy full of toxin."
"Raven's already on her way," Cyborg reported. "Were-beast likes her best, but I don't think we need to worry too much. He changed when Raven had the bad birthday without maiming anybody." Cyborg paused before speaking again. "Be careful. I'm not sure how much protection Beast Boy is right now, and you and Raven are Slade's favorites."
Beast Boy had entirely transformed. "He's up," Robin said quietly. "He doesn't look angry."
Indeed, the were-beast looked nothing more than quizzical as it padded closer to Robin. Robin held his ground, but needn't have worried about a sudden change in attitude. Beast Boy was still in there, somewhere, and somehow the two of them had made peace after everything.
"Um, hey," Robin said directly to Beast Boy, leaving the speaker on his communicator on. "Maybe we can be friendly this time?"
The were-beast's low growl was not reassuring. Taking the hint, Robin let the beast look him over. As long as the claws stayed on the cement and the fangs stayed away, Robin wouldn't try anything fancy. "Guess I should've learned how to deal with animals from you at some point. I know it's all about posture, but the only posture I've learned is how to intimidate people with whatever height I had at the time."
That tone worked a little better. The ruff of fur around the were-beast's head settled into something more flat, and the growling ceased.
"We really need to talk later. About before."
The beast studied him carefully before settling back slightly. Robin thought that was the closest to agreement that they could come.
"Raven's about there." Cyborg's voice was quiet over the communicator. "I'll tell BB to give you the shot, Robin."
"Thanks, Cyborg."
Before Robin could say anything else to the were-beast, Raven walked into the warehouse through the open door. She had one of Beast Boy's spare uniforms draped over her arm. She didn't smile when she saw the two of them getting along peacefully, but she gave one of her rare looks of approval. "I see I needn't have hurried," Raven drawled. Relief was all too easy to read for people that knew her well.
Robin was pretty relieved, too, but he didn't want to look like he'd doubted Beast Boy.
"I didn't think I'd see you again," Raven said directly to the were-beast. There was no softness in her monotone—she sounded crankier than usual, even—but the words had an immediate effect on Beast Boy. "I imagine you're entirely fueled by testosterone right now, and I'm very impressed that you and Robin were getting along so well."
The beast settled back on his haunches, suddenly looking like a very large, very protective dog.
Raven acted as if the response was totally normal. Robin was sure that she had met the were-beast all of once, but she had been the one to support Beast Boy through everything. Robin was still kicking himself for how he had acted toward his teammate. "I don't suppose you're ready to change back."
The beast growled softly. Raven showed no signs of fear. "I thought not, but it was worth the attempt." Raven kept her eyes on the were-beast even as Starfire arrived. "Starfire can partner with you now, Robin," Raven said. "The pair of you can look over the warehouse. If Slade attempts tangling with Beast Boy right now, he'll deserve what's coming."
Robin looked over his teammate and found no trace of reason in his eyes. "He's going to be all right?" he asked. "I mean, he's going to change back."
"Eventually," Raven said. "When he lets me, I'll take him to the shore outside the Tower. It's a lot more secure. Cyborg already headed back so that he wouldn't be patrolling alone."
"You're okay waiting, then?" Robin knew that patience wasn't one of Raven's favorite virtues.
"Fine," she promised. "Completely fine. I owe him one, anyway."
When Beast Boy felt the change finally recede, he relaxed for all of four seconds. That's how long it took him to realize that he was outside, he was naked, and Raven was about five feet away. To his eternal relief, her back was turned, and one of his uniforms was lying on the ground beside her. She sensed something about the change, of course, and then the uniform rose into the air until it was a convenient height to grab. Beast Boy doubted that he had ever gotten clothing on faster.
"Um. Yeah. Thanks," he said when he was clothed, pretty sure that he was going to be purple for the next hour. "What happened?" He half-collapsed beside her on 'their' rocks. Changing into that form always left him exhausted afterward.
"Slade happened."
Beast Boy shuddered. He wasn't sure if that was due to fear or rage. Slade scared him with the way he fixated on people and didn't let go, and contrary to his earlier words, he didn't really want to be next. He only wanted Raven to be left out of it. "Again? Why can't he leave me—er. Metaphorical thought."
"I get the feeling we really do need to talk." Raven's gaze alone was enough to make him realize that he wasn't going to escape talking about it. "You were hiding something earlier."
"Y-yeah. When I was trying to talk to Terra… well, a Slade-bot found me. He seemed to know things." He self-consciously drew his legs up to his chest. "He knew she didn't want me around. I know now that I wasn't being fair to her. I should be happy she's alive and that she has a life again. I don't have to be a part of it. She's safer if I'm not, it's rational."
"Caring about people isn't rational, logical, or easy." The admission wasn't as out of character as Raven liked to pretend. "It's still worth it."
Beast Boy smiled; he knew how much it took for Raven to say things like that. It meant a lot that she'd say them for him. "I do care about her, but Slade would use her against me. He'd get to her to get to—Robin. I didn't, like, do anything?" He remembered telling Robin to get out, and he knew that Robin wouldn't have ran to leave Beast Boy to Slade.
"Growled," Raven promised. "That's it. He had the sense to stand down. You were irritated with him, he thinks, but you didn't even try to go after him."
Beast Boy sighed, reaching for the fuzzy memories of Robin holding his hands out in surrender. That definitely hadn't come easy to the Boy Wonder. "I'm going to catch so much hell…"
Raven's eyes narrowed. "No. You won't."
"I should, Rae. I mean, okay, we don't exactly get along one-on-one." He rubbed a hand through his always-messy hair. "I don't want to be a danger to anybody. Slade can dose me with toxin again, and now he knows that I'm one trigger away from attacking Robin when he does."
"You aren't a danger to me, and I won't let this drive the team apart. Not after everything. You've put up with me when I've done worse, and I hardly mind your were-beast form. When it's just me… you're calm, and it feels like the world went quiet. I can be sure which belong to me." It seemed that Raven was having a long day of long conversations.
"You like him?" Somehow, that surprised him more than Raven volunteering to take the lead in a social situation. "I mean—me, I guess. It is me, even if it scares me."
"I think that your were-beast likes me, too. Starfire told me that you changed. When I thought I was going to die," Raven blurted.
"I couldn't hold back." Beast Boy suddenly knew what that meant, and that Raven might know, too. She was an empath. He never knew just how much that would mean for her. "It was the one time that I entirely agreed with it. I didn't want you to die."
She seemed to miss just what that meant for both of them. Beast Boy couldn't tell if he was hurt or relieved but that was the usual state of things with Raven. He never could tell how he felt or how she might feel in return.
"It's not a chore to come for you," she said quietly. "It's like you need me. Nobody's needed me like that before."
If that was what it meant to her, he just might be able to trust the Beast. Maybe he could even stop worrying about just what she thought about him. Sometimes he was convinced that she'd always be convinced that he was a moron compared to her. "I don't feel so alone when you put it that way." He half-smiled when he realized just why they could talk so long without him irritating her. "I guess that it's for the best you caught me when I don't have terrible jokes ready." He just wanted to make her smile, sometime, but she had started to smile on her own. She didn't need him for that.
"Not all of them are that terrible," Raven allowed thoughtfully. "Just the vast majority of them."
Even that made him feel better. "Thanks, Rae."
"Raven," she corrected.
"Raven," Beast Boy agreed. No matter what had happened or would happen with Terra and with Slade, he'd always have his moodiest friend. That would last even longer if he managed to keep his crush on said teammate hidden from her empathy.
