It looks like this is turning into a weekly update story. Sooo tune in next Wednesday? Anyway, here's part four of Rock Your World.

Beast Boy counted the steady drip drip of water as it fell from stalactite to stalagmite in the dark tunnel beneath the Tower.

"1287."

Maybe if he distracted himself enough he'd stop thinking about Terra, even for a few minutes.

"1288." He'd tried talking to Star, but she was busy fretting about Robin, wringing her hands and pacing along the same 100 or so foot stretch of tunnel for what seemed like hours.

"1289." And Cyborg, ever resourceful, had managed to make a fire from some trash discarded in a dumpster that hid the secret tunnel entrance by which the three of them had entered in the city. After they arrived, he promptly ignited it with sparks from his berserking robotic leg and what little oil he could spare.

"1290."

But that left Beast Boy with nothing to keep himself occupied, and if he kept thinking about Terra he'd go crazy.

"1921." Like when he and Cyborg had been stuck in that crevice, no light, no chance of escape unaided, and surrounded, by the earth Terra so loved and commanded. "Just like now."

"1922." They'd just sat there in the cave, thinking and trying to conserve oxygen.

"1923." He'd passed much of the time trying to justify Terra's actions, considering the most elaborate and meanest of plausible motives behind her betrayal. "Cause what if Terra had been forced into being Slade's apprentice same as Robin?" Then she could come back to the Titans. Back to him.

"1924." Except Robin hadn't taunted them, hadn't had that look of sadistic satisfaction on his face as he single-handedly defeated each of his teammates. His friends.

"9125." There hadn't been any sign of coercion or uncertainty in Terra's case. Could it really be as simple as it seemed? That Terra truly hated the Titans enough to kill them? To kill him?

"9126." What if she didn't really want to hurt any of them? She totally kicked his butt and could've killed him way worse than any of his video game avatars had ever died, but she'd settled with sealing him up in a cave, wholly unharmed, and she hadn't even touched Robin or Raven.

"9127." But she had tossed Starfire off of a cliff, "after KOing her so she almost drowned," he reminded himself. "Plus, Terra probably didn't even know about that air pocket. It was just dumb luck that saw us into safety, not any kind of imagined good will."

"7128." Come to think of it, that boulder she'd chucked at Star had been meant for Robin, and it would've done much worse than a concussion to his human body.

"7129." And something had to be keeping Raven away.

"None of this makes any sense!" He shouted mentally, grasping at the roots of his emerald-colored hair and tugging as though he'd be able to reach his confused, hurting thoughts and rip them out.

"You all right, B?" Cyborg asked, peeking out of the corner of his red eye as he stoked the fire with a rusted pipe.

"Yeah, just lost count," he mumbled miserably.

Cyborg put down pipe and stood. Beast Boy prepared himself for the question he saw in his friend's his eyes, but sighed in relief when the half-robot teen's communicator started crackling.

"Robin?" Starfire piped up. She froze mid-pace and answered the call on the communicator held tightly in her own grasp.

Cyborg answered his at the same time. "Yo, this is Cyborg, what's up?" The crackling intensified for a few tense seconds, then a voice rang loud and clear.

"Stupid technology," Raven's drawling voice complained. "He—o?"

Beast Boy surprised himself as a wide smile—a genuine smile—surreptitiously spread across his features.

"Raven? Can you hear me? I don't have a video image and the audio is sketchy," Cyborg replied.

"Apparently your fancy walkie-talkies don't do so well in mud."

"Mud?" Cyborg repeated.

"I've been trying to contact anyone for hours but the thing hasn't been working. Where have you all been?"

"Terra," Beast Boy said, walking toward Cyborg.

"Was that Beast Boy?" Raven asked.

"Yeah, Star's here, too."

"Where is Robin?" Starfire asked, concern evident in her voice.

"Robin? Not with me."

"What do you mean Robin is not with you. He must be! He left to find you after Terra found us and—"

"Slow down, Starfire," Raven interrupted. "You aren't making any sense. Are you saying Terra attacked everyone?"

"Yes!" Starfire responded exasperatedly. "She attacked Robin and I and trapped Beast Boy and Cyborg. We could not contact you so Robin left to find you while I aided the others. But he did not find you which means he is still out there looking, or—" she gasped. "Hurt and unable to contact us."

"Calm down, I'm sure he's fine," Cyborg said.

"But he should have returned ages ago!" Starfire whimpered.

"Is he not answering his communicator?" the empath asked.

"Robin gave me his when mine fell in the river," Starfire answered, sounding guilty.

"He's probably still out looking for Raven," Cyborg consoled her. "You know how he gets when he as a goal in mind; he loses track of time."

"I don't know, man," Beast Boy disagreed. "Terra's out for blood, and she hasn't had a taste of Robin's yet."

"We must go out and search for him," Starfire said, anxious expression replaced by one of steely resolve.

"Robin told us to lay low—not to call attention to ourselves," Cyborg responded uneasily, clearly conflicted. "And I'm hardly more useful than a night light right now." He pointed out, looking at the sparking circuits on his leg.

"I've been searching for everyone for hours," Raven interjected. "Any place someone might have gone. No sign of Robin anywhere."

"You might have just missed him," Cyborg said. "And I doubt he'd leave a trace anyhow."

Starfire turned toward the exit.

"Where are you going?" Beast Boy asked.

"To find Robin. Raven? Be prepared to heal him if necessary."

"Do you have any idea where he is?" Raven asked. "I'll meet you there."

Starfire nodded gratefully. "He went to the sanitation facility in search of you."

"That's where Terra attacked me," Raven said, and Starfire recognized an edge of panic in her voice. "On my way," she said and ended the call.

"I'll head out, too," Beast Boy offered from Cyborg's communicator. A green eagle joined Starfire as she started gliding toward the city-side exit.

"Guess I'll wait here in case he comes back," Cyborg added, sounding somewhat rueful.

"Call us if he returns," Starfire said, then ended the call as well. "Beast Boy," she started, and turned toward the bird soaring beside her. "I will retrace Robin's route from where we departed, but it would be best if you flew directly there—as the crow flies—to cover more ground."

They flew to the tunnel's exit in silence, but reached the end in due time. Starfire touched lightly upon the ground and reached her hand out to the control panel that would open up the exit Cyborg had installed when the team was still new. She hesitated, her fingers shaking as they hovered above the panel's plastic surface. Beast Boy turned back into his human form and placed a comforting hand on her back.

"Hey," he whispered. "We'll find him. It's Robin we're talking about, remember?"

Starfire offered him a forced smile before pulling him into an unexpected hug. "Be careful, my friend," she whispered. "And stay hidden."

I guess the last couple of chapters have been super dark-which makes sense considering the circumstances, but if you've watched season two then you know there's at least a happy ending! Thanks for the reviews, favorites, and follows, and to Sailor Sea, you'll learn how Raven escaped a couple of chapters from now, which'll have some touching, some hilarious BBxRae moments, I can promise.
