Disclaimer: I don't own X-Men: Evolution or Teen Titans. The conversation that takes place over the T-coms comes from the Titans ep 'Calling All Titans'. I do own Liam, Thomas, Callie and Emma.

I apologise for the delay – I wasn't really in a Teen Titans sort of place. Or an X-Men sort of place for that matter. I have skipped two years in the time-line for the simple reason that very little happened in that time, apart from more training and a lot of nightmares. So here we go…

Chapter Four

Two years later…

With her family's help, Terra had grown from a young girl ruled by her mutation to a confident young woman whose powers were completely under her command. She now went to 'school' at the Institute, catching up on everything she missed by wandering the earth for so long.

After a long day of classes, she walked into her room and deposited her school books on her bed, hearing a small giggle as she did so. Used to this game by now, she smiled. "There seems to be someone in here. I wonder who it could be."

This time the giggle was accompanied by a 'ssh' and Terra lifted the cover of her bed to peer underneath it, to be met by two grins. "Tom, Emma, what are you doing under there?"

Her nephew alone often hid in her room, in a strange game of hide and seek, but Emma Maximoff was an interesting extra.

"Auntie Terra!" Tom launched himself out and Terra caught him easily. "Guess what!"

"What?" Terra asked warily.

"Now, Tommy, don't take my fun." Kitty chided from the doorway.

"Please, Mommy!" Tom pouted.

Kitty leaned against the door-frame. "Oh, go on then."

"Yay!" Tom cupped his mouth and leaned right into Terra's ear, as if about to divulge some great secret. "I get a baby sister!"

"It might be a brother!" Kitty laughed, rolling her eyes.

"Congratulations." Terra shifted Tom to her hip so she could hug her sister-in-law. "When are you due?"

"August." Kitty answered. "Don't have an exact date yet. Emma, Mommy's going home now, sweetie."

"Kay!" Emma crawled out from under the bed, hugged Terra's knees and vanished down the hallway, just as fast as her father.

"The kids love you." Kitty commented, watching Terra sit down with Tom on her lap.

"Well, I love them." Terra laughed as Tom decided to prove his mother's point by planting a kiss on her cheek.

"Tommy, can you go and see Daddy please?" Kitty asked. "I need to talk to Auntie Terra."

Tom slid off Terra's lap and obediently padded out the room.

Terra raised an eyebrow. "What's up?"

Kitty sat down next to her. "How are your nightmares?"

Terra took a deep breath and let it out slowly. That first bad dream had been the first of many; she had learned to sleep with her window open after her powers reached out one night and pulled the pane from the frame, showering her with shards of broken glass. "They've stopped. I haven't had one for weeks. All those chats with Belladonna and Lexa really helped."

Belladonna was the medical advisor at the Institute; one of the only members of staff with no mutant powers. Both women, Terra had learned, were trained as assassins and both women had directly caused people's deaths. Talking things out seemed to help them just as much as it did her.

"Just because…" Kitty took a deep breath. "Things have been really quiet in Jump lately; the Titans are tracking a group called the Brotherhood of Evil…"

Terra gasped. "Beast Boy mentioned them! They used to fight the Doom Patrol!"

Kitty sniggered. "I can't believe they're still going personally. Still, not really our type of bad guy. Your statue's still there; the flowers are reasonably fresh, so someone's been visiting recently. Anyway," she reached into her pocket and pulled out a small circular object, "this was next to them."

"My T-com…" Terra reached out automatically, almost in a daze. "I thought…"

"I guess they need help." Kitty commented hesitantly.

"What do I do?" Terra asked in a whisper.

"Only you can answer that." Kitty pointed out gently.

As if it had heard the question, the T-Com crackled into life. "Calling all Titans. This is a test of our communications system. Is everybody ready?"

Making a second decision, Terra shook her head and gestured for Kitty to keep quiet.

"We're ready in the North."

"And in the South."

"Estamos listos en el oeste!"

"Y el este!"

One by one, other Titans voiced their approval; Terra recognised the voices of a few, but most had become honorary Titans since her departure.

"All sectors are secure." Robin concluded. "Await further instruction. Beast Boy, we're heading home!"

"Wahoo!" Beast Boy cried. "Race you to the meeting point!"

Terra smiled fondly, remembering how much he had hated long T-sub rides.

"I've got you all in my sights." Robin continued. "We should be in range soon."

"And then we'll be home sweet home!" Beast Boy concluded. "Tofu burger, here I come!"

"Are you sure you don't want to tell them?" Kitty asked, still holding the communicator.

Terra shook her head. "It'll just cause confusion; they don't need it right now."

Then suddenly…

"Wait a second."

"Not again!" Beast Boy groaned.

"Robin, is something wrong?" Starfire asked.

Does this mean we're not going home?" Beast Boy whined.

"I'm sorry Beast Boy. I've just got an SOS."

A British female voice came over the intercom. "Argent to Titans, I'm surrounded."

"We're sending help." Robin assured her. "Starfire, fly back and help her."

"If she's in trouble, maybe we should all go and help her." Beast Boy suggested, sounding worried.

"I just got another SOS." Robin disagreed. "Aqualad's in trouble. Beast Boy, I need you to go to Sector 7. Hang on. We just got another SOS in Sector 13. And one in Sector 27. Calling all Titans, prepare for battle!"

"We shouldn't be able to hear all that." Terra whispered. "I guess mine is hooked up to the main five."

"The Brotherhood of Evil have their base in Paris." Kitty told her. "We haven't done anything yet; didn't want to get in their way. The Titans, that is, not the Brotherhood. It sounds weird calling them that."

Terra smiled weakly. "It would."

"Beast Boy to Robin. They're everywhere! I told you we shouldn't have split up!"

Terra's heart dropped into her stomach, which, in turn, dropped into her feet. "Oh God…"

"Come on." Kitty took her hand and pulled her downstairs to the computer; hooking up the communicator, she tapped a few keys. "He's over the Pacific. Do you want us to help?"

Terra frowned in thought. "No. No, I'll handle it. I'll call you if I need you."

Ten minutes later, Terra was on a slab of rock speeding over the ocean, crouched low so the turbulence didn't knock her off. Unfortunately, there hadn't been much time to get exact coordinates, so she had a race against time to find him before something awful happened.

Or something even more awful, she supposed.

Then, up ahead, an explosion rocked the sea, forcing Terra to pull the rock up sharply to avoid getting hit by the wave that rose to meet her. Several pieces of metal shrapnel flew towards her and she dropped lower, letting them fly over her head, before urging her platform on.

The T-sub capsule had been blown apart completely; only a few recognisable pieces floated on the calm water.

The remains of a large heart floated a few metres away and Terra breathed a sigh of relief. It looked as though Beast Boy had taken care of it himself.

The hero himself was sat on the edge of part of the capsule with his back to her, staring at something in his hand. "Robin…" He tossed it over his shoulder with a frustrated groan and Terra caught it to see the remains of a communicator.

Her heart sank again. It hadn't broken in the fight; it had been programmed to blow. Her own was with Kitty so the X-Men could track what was happening and she was out of telepathic range.

Way out.

For a second, she faltered. Was she really doing the right thing, leaving the X-Men out of this? Why would Robin set the communicators to blow up? Terra knew it must have been him; no one else knew how to as far as she was aware.

Of course a lot of things could have happened in two years.

Her attention was drawn back to the young man in front of you as he buried his face in his hands in a rare show of desperation. "I need help!" He lifted his head again and glared at the sky. "Don't I get even a little help here?!"

Terra took a deep breath. "That depends. How desperate are you?"

"You have no idea." Beast Boy sighed. Then… "Terra!" He jumped to his feet and spun around, causing the sub to move precariously beneath him.

"Careful." Terra caught his arm. "I'm earth, not metal."

"Terra!" Beast Boy repeated, gaping at her. "How…? When…?"

"Well, that's the difficult part." Terra sighed, taking a seat and letting her legs dangle over the edge of her rock. "Wanna lift?"

"Yes please." Beast Boy pulled himself up onto the floating platform and sat next to her. "Any idea where we are?"

"The middle of the Pacific." Terra answered. "I can't get more specific, I'm afraid."

"That's fine." Beast Boy pulled something from his belt and consulted it. "There's an emergency bunker in a general…that way direction." He waved a hand behind him. "Anyone else will head there. Then we need to find out where the Brotherhood base is."

"Paris." Terra filled in promptly. "I'll explain on the way." She lifted a glowing hand and the rock moved in the direction Beast Boy had indicated. "I'm surprised you didn't want proof it was me."

"This is proof enough." Beast Boy gestured to the rock beneath them.

"I could do this when I worked for Slade." Terra muttered, the words leaving a bitter aftertaste in her mouth. "Doesn't mean it was me."

"Terra, Raven would have known if you were an impostor." Beast Boy pointed out quietly.

"But not if I was possessed." Terra finished. "Slade's a telepath. He's also known as Mesmero; the X-Men used to fight him. And speaking of the X-Men," she pulled her communicator from her pocket, "they're sitting this one out, but they're only a call away if you need them."

"Wait, wait, wait." Beast Boy held up a hand. "You were possessed; I get that bit. Actually, it doesn't surprise me; I was wondering how you changed your opinion so quickly. But how do the X-Men come into it? You've been stone for two years!"

"No, I haven't." Terra admitted quietly, tucking it away again. This was the hard part. "I wasn't even stone for two days. They helped me out of it within an hour."

"Terra…" Hurt was evident in his voice.

"It's complicated, Beast Boy…I couldn't face you…"

"Terra…" The hurt was gone now, replaced with affection so strong she could almost taste it. "It wasn't your fault; we'd have listened to you…"

"It wasn't you." Terra cut him off, finally turning to meet his eyes. "It was me. Up until a week ago, I couldn't sleep without reliving what happened. And…" now her gaze averted, not wanting to make the admission but wanting to make him understand "…my powers used to activate themselves." Her hand automatically moved to the inside of her lower arm and she flinched, hoping he hadn't noticed.

"They hurt you." Beast Boy took her hand, now gloveless, and turned her arm gently, allowing him to see the faint scars that still criss-crossed across her skin.

"They felt I deserved it." Terra whispered.

Beast Boy didn't release her hand, but wrapped his other arm round her shoulders and held her close. "We've forgiven you, Terra. Even if there's nothing to forgive."

"Thank you." Terra murmured, feeling a great weight lift from her shoulders.

"Now how did the X-Men get involved?" Beast Boy asked, pulling away.

Terra smiled now. "Well, you're never going to believe this…"

"…so Kitty tracked the signal coming from the T-Com and here I am." Terra finished. "But I guess my T-Com won't do her much good now, huh?"

"So your sister is second-in-command of the X-Men; her husband is the team-leader?" Beast Boy concluded. "And you've got a brother and sister-in-law there too."

"Yup. Plus eight nieces and nephews with another one on the way." Terra's sharp eyes spotted land down below and she angled the rock downwards. "So I guess that explains everything."

"Not quite." Beast Boy disagreed. "Where's your T-Com?"

"With Kitty." Terra admitted. "Our communicators work differently, so she kept it to track our progress."

"That plan's gone to hell now." Beast Boy commented. "What are they going to do?"

"Nothing." Terra shrugged. "Not unless I ask them for help. Should I?"

"Why are you asking me?" Beast Boy asked. "Robin's the leader."

"Robin's not here." Terra reminded him. "And we can't very well ask him, can we? What happened to the communicators anyway?"

"Robin set them to blow." Beast Boy sighed. "The Brotherhood of Evil had been listening apparently. You never activated yours; that's probably why they didn't come after you."

Standing up, Terra stepped down as the rock landed on a sandy beach. "Where are we?" She asked, stretching.

Beast Boy didn't answer.

"BB?" Terra turned to look at him, but he wasn't listening; he was watching her instead, with a slightly dazed expression.

She was a good head taller than she had been when they'd last seen each other and Kitty had helped her fix her hair so it lay in waves rather than hung straight down as she used.

Her Titan uniform was gone too, replaced with an X-uniform that was closer to the adult team than Generation X, who wore plain black spandex body-suits. Her uniform now comprised of a black tank-top and a black skin-tight trousers with an X-marked belt, almost identical to Kitty and Jean's X-Factor uniforms and tighter and more revealing than anything he'd ever seen her in before.

Self-consciously, Terra brushed away a strand of hair as it fell once more into her line of sight and her companion smiled at the familiar action.

"Here." Beast Boy rooted in his pocket and pulled something out. "You'll want this."

Terra reached out and he dropped into her open palm a small butterfly-shaped hair clip. "You kept it?" She pushed the lock back and pinned it firmly into place. "So which way to this emergency bunker?"

"Er…" Beast Boy pulled out the same object he'd consulted earlier. "This way." He nodded to their right. "Of course I kept it. What else was I going to do with it?"

"Well, you did think I'd betrayed you." Terra reminded him quietly, following him. "I can think of a few things."

Beast Boy stopped walking, causing her to abruptly do the same so she didn't bump into him. He turned to face her, looking more serious than she'd ever seen him. "You need to understand one thing, Terra. I never hated you for what happened. Losing you was one of the worst things that ever happened to me; you can ask any of the others. I was a mess for weeks. But that wasn't because of the reason you'd gone. It was just that you'd gone."

Terra felt another pang of guilt. "Beast Boy…I don't know if I'm coming back…"

"But you're here." Beast Boy cut her off. "That's what matters."

Terra smiled shakily, not hesitating to hug him tightly. "You really are the best friend I've ever had. Now let's get moving before I start crying again."

AN: Yes, this is a BB/T fic as I probably should have mentioned earlier, but didn't think to. Review please!
