The team had begun to notice Robin's… mood. He strode around whistling and doing dishes and making breakfast. He left the sanctity of his room a lot more often and trained a lot less, as if he were getting practice in while he was asleep at night – if he did still sleep. Always yawning, a tired smile on his face, he would prop his feet up on the coffee table and play a videogame by himself. Obviously he should be sleeping. He sat on the roof a lot and looked at the sky or wandered outside, taking in the fresh air. There was barely a moment when he wasn't floating on air at some point during the day. His strange happy mood was so foreign that his friends began to worry that he was a clone, or a robot.

Just the sound of his footsteps alerted the others to exchange glances and watch as he strode into the common area to check the computers for any alerts in the city. He was ruffled, still in his civilian clothes, and as he leaned over the console Starfire was caught staring by Raven. She blushed and ducked her head until Robin had left again, twirling a flash drive around one finger, the other hand slung into his jean pocket. His yawn echoed down the hall as the doors slid shut behind him.

"Why does Robin act like this?" Starfire blurted. "He is always jovial, and wears normal things, and he is sleeping less and less! Is he sick?"

Raven turned to look over at her, smiling. "I'm not sure what's going on with him, but he doesn't seem to mind it."

"He may be being brainwashed!" Starfire lamented.

"Chill out, Star." Beast Boy leaned over his tofu waffles with a knife and fork, grinning. "I'm sure Rob just has a girlfriend or something."

The alien girl's entire face crumbled. She sank down onto the couch, hands on the back, and gave BB her best puppy dog eyes. "You… you do not really think so, do you?"

"Sure. Why not? He plays everything a little close to the chest; if he did have a love life, we'd be the last ones to know." Cyborg piped up, continuing to tighten a bolt on his knee. "He's happy for once. I think we should just let him be happy."

Starfire, now depressed, left her friends to relax and drifted out into the hall. Could it be true? Her Robin, in love with someone else? It was heart wrenching. She followed the smell of cologne and wind, sadly floating along, until she bumped her forehead into Robin's door. Big, sad green eyes lifted to the name engraved on the door. Who could it be? Maybe someone he'd met on his escapades she insisted he have to take a break. That must be it.

The door swished open, making her yelp in surprise, and Robin stood there blinking. "Starfire?" He asked curiously. "What's wrong?"

He looked so handsome, and so calm, and so tired, and so happy, and Starfire felt in her heart a throb that she found was hurting her because she was not the cause of it. "Robin, would you tell us if you were… involved?" She questioned.

"How do you mean?" Robin managed. He felt a flustering blush climbing into his cheeks.

"I mean involved… romantically. With someone else." Starfire explained hopefully.

"I…" Trailing off, Robin stood back a bit, glancing over his shoulder like he wanted to put on the green sweater again, and bury himself in it. His face glowed with blush. Biting his lip, he took a deep breath and turned back to her guiltily. He saw her hopeful look and sighed. "Starfire, I don't really know a lot about anybody's private life. I usually just… keep mine to myself."

"Oh." Starfire's smile fell away. "I see."

Sighing again, Robin ran his fingers through his hair. "I suppose I should. In case anything happens. I mean, I could go missing and no one would even know where to look," he said, mostly thinking aloud, and Starfire looked alarmed.

"What do you mean, go missing-"

BLEEP BLEEP BLEEP BLEEP

Both of them looked up as the alarm systems began to go off. Shortly after Robin scrambled back into his hero get-up, Starfire waiting outside eagerly, they ran to the common area to see what was going on. "What is it?" Robin questioned Cyborg, who stood at the computer.

"Some weird readings coming from the coast," Cyborg replied. "An attack on Northside beach!"

"Titans, move out!" Robin shouted, and they bolted.

The beach was crawling with humanoid creatures, deathly thin and ghastly looking; their skin was blue and covered in barnacles and seaweed, their faces gaping holes. They were chased the screaming civilians on the beach and wrestling them into nets on the sand. Amidst the chaos, Starfire dropped Robin from above, allowing him to swiftly knock out a handful of the things.

"Sirens!" Raven called from another point where she was wrestling with a group of them over a net. They kept blasting sound out of their mouths. It was jarring noise, filling your head and leaking out your ears, taking control of your thoughts.

"WHAT?!" Cyborg demanded, blasting his way through them. "What the heck is a siren?!"

With a sweep of her arm, Raven took out a siren trying to tie up a sun bather. "They use their sound to make you docile, and control your mind! They're using it on the civilians!"

A familiar cry rang out and they all struggled to get a glimpse of Aqua Lad. He was fighting off a small horde of sirens on his own, and Robin ran to help him out, swinging his boe staff as he went. Left and right, getting clawed and screeched at, the Titans cleared off the beach together, rounding up what sirens they could into the nets, and Raven put a large black bubble around them to seal their sound inside. "Was anyone hit?" Robin looked around at his team. Cyborg shook his head, and so did Raven, but Starfire was busy rounding up the run-aways… and Beast Boy was walking around acting like a zombie. "Beast Boy!" Robin called sharply, worried, and the green titan laughed and rubbed his head.

"I'm just kidding! These guys are weird, though, right?" Beast Boy poked the bubble with one finger, and Robin blew a sigh of relief. Bruised but ok. Starfire flew back, dropping in the extras, and landed neatly beside him.

Aqua Lad patched a cut on his arm. "They broke out of Atlantian prison. If we can round them up, we'll throw them in a deeper hole this time." He looked to Robin. "Thanks for the help."

"Anytime," Robin replied easily, but he was wondering where Kid Flash had been.
