"Robin, I'm really sorry," Cassie said, following him into the lounge of the cave on day, after a failed mission.

Robin ignored Cassie, and sat down onto the couch without looking her way. If he had looked, he would've seen how sincere and apologetic she was, and how her blue eyes trembled slightly in hope that he would forgive her.

-Flash Back—-

"Wondergirl, wait!" Robin said in a hasty voice, as he and Cassie searched through an empty warehouse in Gotham city.

Sightings had shown that some of 'the light' would be here, or would have something to do in this warehouse, so Nightwing had sent Gamma, Tim and Cassie, to go check it out and see what was going on.

Nightwing had especially thought that this small mission would be a great way to get Tim ready for taking over the team, later on of course.

"What? I'm doing as Nightwing told us, searching the warehouse," Cassie hissed back at him, turning around to face the bat before going back to what she was doing.

Robin rolled his eyes at her, and pushed the door which led into a tiny room, "Over here," he whispered, motioning her to come in.

Wondergirl nodded, and quietly followed him inside, her eyes widening when she saw the room had weapons hung all over the walls, and strange utensils filled with blue liquid.

"What're you doing!" Robin demanded in a low voice, glaring at her when she picked up one of the blue liquid things.

Cassie rolled her eyes, "What? Aren't I allowed to check things, Mr. Detective?" she said, crossing her arms.

Yes, these two hardly got along in missions. Cassie was hard headed, and hardly listened to him, being strong willed and thinking she could do things by herself. Half of the reason was because she wanted to prove herself, and most people didn't really let her, either knowing she was good, or thinking she wasn't good enough. Still, this made her defensive.

Robin tried to listen to her, but that didn't mean he would always. He, in a way, was also trying to prove himself. He wanted to show the other heroes that he would be responsible for becoming leader when, and if Nightwing had to step down.

On this particular mission, he was stressing about making sure that it went well, and Cassie wasn't exactly helping with his problem. He knew Nightwing had assigned this mission especially for him, and he didn't want to let him down.

"Just be careful," Robin replied, looking at her evenly as she rolled her eyes once more, and turned back to the weapons.

"Wait, we shouldn't touch these. I'll contact Nightwing and tell him about it," Robin ordered suddenly, and Wondergirl gave him a short nod.

But just before Robin could talk to Nightwing, Cassie accidentally tripped on something and let it break. It must have been glass, because as it shattered, a loud sound erupted in the small room.

"What did I say?" Robin hissed, and Cassie opened her mouth to say something, but an alarm starting ringing loudly outside.

Robin shot a glare at her, and muttered something under his breath, as he hurriedly tried to contact Nightwing.

"Robin to Nightwing, come in," he said, pressing the button of the communicator in his ear, hoping Nightwing would answer because he heard footsteps outside.

Wondergirl looked around hurriedly, "We should go," she said quickly, looking for approval from Robin.

"Oh you think so?" Robin snapped at her, making Cassie flinch before she returned his even stare. Tim was particularly harsh on Cassie at times, even though he never paid attention to it.

Maybe this was the reason Wondergirl they didn't agree in things. Either way, Robin had started something, and it had woven itself into a web of annoyance and hatred towards each other.

"Robin, now!" Wondergirl warned, as the footsteps became louder, and the sounds of voices came.

"But this?" Robin muttered, glancing around at the room. Cassie gave him a look which said 'if we don't go, we'll just get caught,' and Robin nodded hastily, "Let's go-"

"Go where, might I ask?"

The two young heroes spun and saw Sportsmaster leaning against the door way, a smirk on his face when he saw their panic.

"Go!" Wondergirl exclaimed, suddenly snatching the explosive bird-a-rang in Robin's hand, and throwing it onto the ground, making it explode and the weapons burst into flames.

Robin looked in horror at what she'd done, but didn't have any time to object because Sportmaster growled and lunged for them, angry at what had happened to the many weapons.

Cassie yelped, and threw a punch straight for his face. It hit, and Sportsmaster stumbled back from the strength, giving Robin and Wondergirl time to escape.

The two ran out, breathless and panting as they got away from Sportsmaster and some other people who came after them.

"What did you do!?" Robin shouted at her as they ran to hide in an alley, "You just took a bomb and ruined all the evidence we had!"

Cassie opened her mouth to tell him something, but Robin was on a rampage, "Do you hate me or something? Why couldn't you just obey orders?"

"I wa-"

"Just..be quiet, I don't want to hear it," Robin cut her off, shooting her a glare before putting a hand to the communicator, where Nightwing had just replied.

"How'd the mission go?" Nightwing's voice came.

"We messed up," Tim replied, "I'll give you the details when we get back to the cave,"

Nightwing replied something, but Cassie wasn't listening anymore. She walked behind Robin as the two went to the nearest zeta tubes.

-End Flashback-

That was yesterday, and after they got back to the cave, Robin followed Nightwing somewhere to give the details of what he'd heard and seen, without another look at Cassie.

Today, Cassie had been trying to tell Tim that she was sorry for what had happened, and he was overreacting, which indeed he was.

"Look, Wondergirl," Tim spun around, making Cassie cringe when he called her 'Wondergirl', "I don't care, okay? You messed this whole mission up and-"

"Since when did I mess this up? I got us out of there!" Cassie interptted, her own anger kicking in.

Robin ignored her, "-The mission was a fail, and I don't want anything to do with this,"

Cassie's eyes narrowed, "What do you mean?" she asked in a low, demanding voice.

"What I mean is, Wonder girl," Robin answered, not calling her by her real name, "I don't want anything to do with you. Just leave me alone, and in missions, try to be paired with someone else," he said harshly.

Cassie was surprised. He'd taken this so badly, and she couldn't help but feel very guilty. He hadn't even listened to her part on this, and was already judging.

"So you want me to stay out of your way, then?" she asked him slowly, her voice a little shaky, but she steadied herself quickly before he could notice anything.

"Gee, maybe you're not that bad, you guessed right," Robin said flatly, looking away from her, "Just go," he added in an exasperated voice.

Cassie felt tears glistening in her eyes, but she blinked them away. She was hurt, but also angry. He couldn't just treat her like this, and if getting out of his way was he wanted, she'd gladly do so.

"If that's what you want," Cassie muttered. It wasn't with anger, or annoyance, it was simply emotionless but Robin thought he heard a ting of hurt in her voice as she walked out of the room, leaving him alone.

You really know how to mess up, idiot! Gahhhh I hate Tim right now, so overreactive.

Quick reminder: I was the one who wrote this mess...so...uh..yeah

Updatin' soon!

See ya,
