Destiny and Donatello reach TCRI in record time. It's relatively empty inside save for the occasional, aimless Kraang droid that patrol the lower levels at night. Destiny slices of said aliens apart when it crosses their path, punts the Kraang brain as far as she can, and snatches up the robot head with hardly a blink. She tosses it to Donatello, who manages to catch it even if his head isn't in the game.

"This has gotten really easy," Destiny says. "You know, ever since we annihilated the Kraang and all."

Donatello gives a weak nod in response. They head for the elevator, go inside, and Donatello uses the Kraang head to activate the Kraang-exclusive levels of the building. The elevator starts its steady climb to the correct floor.

The only noise is the echoing clank of Donatello throwing the robot head aside. Destiny fiddles with the hilt of her blade, starting to bounce on her feet.

"So...how are we supposed to find Mikey's phone?" she asks.

He holds up his phone. "Tracker."

"Oh, right."

His russet eyes fall to the floor so that it too gets a fill of their miserable gaze. Destiny bites her lip and tries with all her might to just let the silence happen, but it's worming its way past her defences. She exhales heavily.

"Donnie, I'm worried about you," she admits.

He snorts. "Yeah, tell me something that I don't already know."

She doesn't let his comment deter her. "It's been two weeks. Yes, it's still fresh and you're not used to it, but moping won't help. Moping isn't going to make her break up with Casey."

He stiffens, jaw clenching. "I know that," he utters. "I can't help it. I loved her, Des, and I thought that maybe she was starting to love me too. Turns out I was wrong."

Destiny frowns. There's a lot that she could say. She could spew the same general "it'll get better" and "no pain is forever" shtick, but the truth is, she's having a hard time believing it for herself. The last thing Donatello needs is for her to be a raging hypocrite.

"Have you ever thought that maybe, just maybe, you don't influence someone else's choice and that you shouldn't blame yourself for what happens?" she suggests in a quiet voice.

"Are you saying that for yourself or for me?"

"Both, okay? At least I'm trying, Donnie," she snaps. He flinches and she instantly freezes. Her face crumples and she slumps against the elevator wall, muttering a faint cuss to herself. "I did it again. I'm sorry."

He shrugs. "It's fine," he mumbles.

The elevator reaches the correct floor and lets out a soft ding as the doors slide open. Donatello heads from the elevator and Destiny goes after him, ears flattened against her hair. He hardly looks at her as they traverse the winding hallways.

"Donnie, I was just trying to suggest that your life isn't over and that we can find something else to...I don't know, reignite the flame," she says. He doesn't make a sound. "That's all, okay? It's hard enough for me, trying to act like nothing's wrong. Think of everything we've been through lately. You got through that, so—"

"Des..." He sighs, stopping in his tracks. She bumps against his shell and he turns around. His eyes are watery. "This isn't something you can cure. Everything's just...hitting me at once. April's gone, Diaval's gone, the Kraang are gone, and I feel like I've lost something too. I just can't figure out what that is."

She doesn't meet his eyes, her fingers curling into tight fists against her legs as her jaw clenches hard enough that a vein in her neck bulges slightly. Donatello reaches over and brushes her shoulder as she inhales sharply through her nose. She's already starting to tremble.

"We'll both be okay," he states. "It might just take a while."

"Yeah," she says, her voice on the edge of breaking.

He hooks his arm around her shoulders and they keep walking, bumping hips and shoulders and sometimes heads but not minding any of it. Donatello's phone goes off suddenly and makes them separate, eyes wide.

"Oh, it's close!" he says, looking up at the gaping hallway before them. A shell-shaped object lays a few feet away and he hurries to it, scooping it up and pocketing it in a flash. "Got it," he says.

"Mission accomplished. Go D-team," Destiny says, extending her hand for a fist bump.

Donatello connects their fist and, as they make it explode, there's a loud bang from far off. The teenagers startle and look down at their fists, then up at one another.

"Wasn't me," Destiny says.

"Me neither," Donatello agrees.

They go back to shell and scan the hallways for incoming enemies, hands hovering near their weapons, but nothing comes. It's quiet and deserted enough that if a tumbleweed rolled past in that moment, neither of them would be surprised. Donatello slackens, fists unfolding, when he notices a large window-like glass pane set in the wall at the end of the hallway, sealing it off as a dead end. It resembles the Kraang cells where they keep prisoners, but the window is larger.

"Des, look," he whispers, nudging her. He points to the supposed cell. "That's weird. We should check it out."

She arches an eyebrow, glances at the door again, then shrugs. "If you want."

They head for the strange window. Upon getting closer, they find that the window does lead into a separate room and the wall isn't a wall at all, but a giant door. Above the keypad to the left of the door is a label that reads "SUBJECT 60184".

Donatello can't explain it, but his heart jumps. His eyes widen and he picks up the pace, making Destiny do the same although she's confused as to why they're moving faster. He reaches the window and peers inside like a child when they visit the zoo or aquarium for the first time.

Unlike a zoo or aquarium, there's no fish or exotic animal lurking within the large room. In fact, there's just a girl, and a very strange, very non-human girl at that. She wanders around, jotting down something on the notebook in her hand while occasionally sparing a glance at the smoking remains of what looks like a test tube that sits on her desk. She doesn't look that much older than Donatello.

Her face is still rounded with the remnants of baby fat that puberty hasn't yet shaved away, framed by only three separate pieces of blonde hair that hang on the outer edge of her eyes and directly between them, dangling above her nose. The entirety of her head is bald and decorated with silvery circuit wiring that runs down her neck and spreads across her entire body, right to her fingertips, but leaves her face bare. Her eyes are electric blue and thrum with energy, glowing and fading with blue light. Her only clothing is a white jumpsuit and white sneakers.

Donatello's mouth falls open. Questions start to race through his mind faster than Michelangelo on a sugar high. Is she a mutant or is she a complete robot that the Kraang built? Is she half human? She's fantastic!

"Woah, is she a mutant?" Destiny asks, snapping the purple-masked turtle from his thoughts.

He clears his throat. "Uh, maybe a cyborg," he says. He takes some time to observe the discarded piles of notes, the bed that looks as if it has never been slept in, the desk littered with metal and spare parts, and the pile of old calendars in the corner. "She looks like she's been here a while," he says.

Destiny lifts her fist and taps on the window three times. The cyborg jerks her head their way and for a moment, the spectating teenagers swear that her eyes flash like a camera going off. Her face stays absolutely straight as she walks towards them. Her movements are graceful, nothing like a stereotypical robot's jerky stride.

"Who are you? What is it that you require?" she asks, her words clipped and mechanical. Donatello notes that she sounds very similar to Siri, but less annoying.

Destiny lowers her hand, tail lashing. "Who are you?" she retorts.

The cyborg doesn't even blink. "I have asked you first."

"I knocked on the window to ask you, so...my intention was first."

Finally, the strange girl blinks. "I suppose, but your answer is right before you on the label outside this room. I am Subject 60184." She tilts her head. "You knock on my glass to ask me personally for a name. Why?"

"I was curious," Destiny states. "Is that a crime?"

"A curious mind? We must be more similar than I originally thought. What sort of droid are you?"

"Droid? I'm not a droid. I'm a human!" Destiny stops. She shakes her head. "Wait, no. Not human. I'm a mutant, a wolf mutant, but I look pretty human."

The girl's eyes flash and Donatello's dangling mouth seems to dangle even more. "First you say human, then you say mutant. Interesting," she says. Her eyes travel to Donatello slowly. "And you? Surely you are not both human and mutant."

Donatello instantly straightens up and shuts his mouth, eyes still wide, and her pupils seem to swivel as she focuses in on him. He swallows as her intense gaze locks him in place and they end up staring at one another. The moment breaks only when Destiny elbows Donatello in the side.

"W-What's your real name?" he stammers as his entire face flushes.

"The Kraang gave me no name. I am Subject 60184."

"Oh, that's too bad," Donatello says. His voice is slightly squeaky.

When he says nothing more, Destiny again steps in to break the awkwardness. "He's Hamato Donatello. I'm...Hamato Destiny."

"You do not look Japanese," says the girl.

She looks away. Her facial expression still doesn't change, although she seems like she's falling deep into thought. If she notices Destiny smack herself in the face, the cyborg doesn't indicate it. There's a pregnant pause where the odd trio doesn't make a sound, then she spins to them and her eyes flash with a spark of electricity. Destiny barks and instinctively grasps Donatello's arm.

"I wish to leave this place, and I would deeply appreciate your assistance in the matter. Can you offer that needed assistance to me?" Subject 60184 queries in a rush.

"Huh? Leave?" Donatello repeats.

"Yes, I deeply require it if I am to remain a normal, functioning being. It is imperative."

Destiny and Donatello share a quick glance. Donatello shrugs and, before Destiny can argue, he moves to the control panel and starts fiddling with dials and buttons. Destiny scoots to his side and leans down to his ear, eyeing the cyborg standing at the window.

"Maybe we should call Leo first," she starts. "We can't just—"

"She's obviously a prisoner. She needs help," he says. "We'll talk to Leo when we get back."

"Donnie..."

He looks up at her with a frown. "Listen, she's different and...I have a really good feeling about her."

"She might be working for the Kraang. What if she turns on us?"

He musters the saddest, most "kicked puppy sitting in the rain" look that he can. "She...she'd distract me from certain other people—"

Destiny caves so fast that it's not even funny. "Fine."

He smirks and turns back to the box. After another moment, the door slides open with a little puff of smoke from the control panel. The cyborg steps out of her cell with hardly a smile.

"Fantastic. Shall we go?" she asks. Her tone and face don't fluctuate.

"Uh...yeah. Okay," Destiny says with a slow nod.

They head back the way they came, Donatello and Destiny remaining wary of their new companion. She's creeping them out a little, although neither of them will admit to it. If she would blink more often and maybe move her face in ways other than subtle eyebrow lifting, she'd be less unnerving. They, of course, don't dare say anything like that out loud considering their own standing in society.

"You need not worry about betrayal. I may have been raised by these creatures but I detest them in many ways," the cyborg says after a long period of silence.

Destiny's head whips around. "How did you—"

"I heard you outside the cell. The door is not soundproof. I thought I should put your fears to rest."

Donatello, becoming more intrigued by the minute, asks instead, "Raised...you were raised by the Kraang?"

"Indeed. They made me into the fantastic piece of machinery that I am today." She blinks. A hardly audible buzzing sound emits from the base of her skull. "Now, you may want to hurry. Those that are left will be coming any moment."

"Oh! Thanks, Subject 60...0...uh..." Destiny trails off.

"60184."

"Right, that."

They reach the elevator, punch the button, and begin their descent. Destiny scoots closer to Donatello and nudges him with her shoulder.

"You sure about this?" she asks.

He nods, watching the girl stare intently at the blinking elevator keypad. "Positive."
