"And here we have Jupiter!" The Doctor exclaimed, gesturing to the large window in front of the pair, revealing the planet Jupiter.

"Wow..." Ruri breathed out, taking in the beautiful view. "It's... Amazing. Like, really... Wow." She laughed, shaking her head.

"I know." He smirked, looking at her out the corner of his eye, seeing her smiling wide. "All of Jupiter's moons are occupied, full of different species." He began. "Species visiting from all over the galaxy. Jupiter's moons are like the... London of the galaxy..." He shrugged, not sure whether it was a good comparison. Ruri laughed lightly.

"I can't believe it. I'm stood on a moon. A Jupiter moon. And I'm looking at Jupiter." She jumped up and down, looking at him. "I can't believe it." She tugged his arm as he laughed at her reaction. "It's brilliant." She calmed down, composing herself. "Yeah it's cool." She said in a monotone voice, shrugging.

"Done?" He raised an eyebrow, amused.

"Meh." She smirked, before she could say anything else, a loud alarm went off, echoing the halls. The Doctor spun round, looking at how empty the place was as people started moving out the room. "Doctor? What's happening? Why is there an alarm?" She questioned, watching the people leave.

"I don't know." He paused. "And I don't like it." He began to follow the others out of the room, Ruri taking one last look at the planet outside before following after him.

"Is it a fire alarm or something?" She asked, folding her arms as she walked beside him.

"I'm going to say or something." He muttered, seeing blue skinned aliens appear, looking suspicious. "Excuse me!" He called, pulling the psychic paper out, showing the aliens. Ruri turned round, seeing he was suddenly the other side of the room, she sighed, about to head over when someone bumped into her, knocking her back.

"Ouch." She muttered as she, looked at who she bumped into. They had already passed her. She turned to see them wearing a white robe with a hood, not showing their face.

"Hmmm..." She narrowed her eyes, shaking her head, looking round for the Doctor to see he had disappeared.

"Oh... Come on. What's rule one? Don't wander off. So what does he go and do?" She whispered to herself, frustrated, spinning round to see no one was there, everyone had gone. The alarm cut off, the room going dark.

"Perhaps it was closing time..." She wondered, heading to a door, waiting for it to open. It soon opened, revealing another dark room, everything was silent.

"Hello?" She called, looking round, trying to see anyone, but saw nothing. She was about to turn back when the door shut, locked. "Oh great." She sighed, walking forwards. "Only way is forwards." She realised she had put a small torch in her pocket incase of emergencies, so she pulled it out and turned it on. Although it was only a small light, it lit up where she needed to see - a head of her. She looked round, seeing closed up stalls. "Must be the market place." She wondered, carrying on. But something made her stop as she heard a loud banging sound come from above. She froze. Standing still. Staying silent, she heard it again, but from in front. She felt uneasy, not liking being alone in the dark on a moon. It could have been anything with her.


"Ruri!" The Doctor called, seeing no one there. He sighed. "What do I tell them? Rule one - don't wander off! Do they listen? No. Apparently I have a face that no one listens to!" He exclaimed, frustrated. He turned to see a small blue skinned boy, staring at him with an odd expression. "Oh... Hello." The Doctor grinned, stepping over to him. "Have you seen a girl about this high-" He lifted a hand to just below his shoulder height. "Ginger hair, very dressy... Oh! And freckles." The boy gave him a blank expression still. "Erm..." The Doctor narrowed his eyes, waving a hand in front of his face. "My names the Doctor, if that makes you feel any better?" He shrugged, hoping for a response. "Where's your parents?" He looked round. "Did they wander off too?" The small boy nodded. "Right then. Let's go find mum and dad and Ruri." He held out his hand for the boy, who hesitantly took it. They began walking along when the boy spoke.

"Yes." He said quietly.

"Yes what?" The Doctor glanced down at him.

"I have seen your friend."

"Oh good! Where?" The boy then pointed to above. "How did she get up there?" The Doctor thought out loud.

"She has been taken." The boy informed him, causing the Doctor to stop.

"Taken? By what?" He knelt down to the boys height.

"We can't speak of them, or we'll be taken too." He whispered, making the Doctor concerned about what he was talking about.

"You can trust me. I'm here to help. I once even had a badge that said that." He looked round, seeing no one still. "Where is everyone? What was that alarm?"

"Closing time." The boy said louder, the Doctor slowly standing up.

"I don't remember there being a closing time on Europa..." He recalled the last time he was on the moon, remembering no alarm or disturbances. "Something's changed... The air is different. Why?" He asked himself. "Something is doing more than visiting this place... It's habitating it." The boy just stared at him, still a blank expression. "What's your name?"

"Rennarni." The boy told him, the Doctor smiling.

"Well then, Rennarni, let's go find everyone."


Ruri slowly began to stir, confused as to what had happened. The last thing she remembered was hearing the banging. Nothing else. She opened her eyes, adjusting to the lighting. She found herself in a boxed shaped room. She stood up, dusting herself off. She saw a door, she ran over to it and tried to open it. Locked. She began to feel panic rise in her chest. For one, she hated small rooms, they made her feel odd, and two, why was she locked in a small room? She remembered she had her phone in her pocket, she felt around when she finally found it. She quickly opened it but before she could do anything, someone appeared in front of her, staring down at her. She instantly backed away, shocked by their sudden presence.

"You will not use any devices." It stated, it's voice low and dark. The creature was wearing a black hooded robe, hiding it's face - similar to the one wearing the white. Ruri nodded, putting the phone down on the floor, stepping away, not wanting to argue with them, knowing they had the upper hand. The phone then disappeared. "You will stay." It stated, disappearing. She let out a long breath which she hadn't realised she had been holding in. Now how was she supposed to contact the Doctor...


The Doctor wandered along, heading back to where he had lost Ruri, using the sonic screwdriver to open the locked doors.

"We can't go back in there, it's closed." Rennarni told him, a flash of fear over his features.

"And who told you it was closed?" The Doctor turned to him. "Did anyone even tell you what that alarm meant? Or did you all just assume it meant closing time?" Rennarni narrowed his eyes. The Doctor was right. No one had told them about the alarm, everyone just assumed it meant closing time.

"If the alarm isn't closing time... What does it mean?" He asked, concern in his voice.

"I don't know. And I don't like not knowing." He pondered for a second. "If something else is here... It could mean anything. It could mean; play time or dinner time." The boy looked scared, he didn't want to find out his parents may have been eaten by other aliens. The Doctor noticed and soon regretted saying it out loud. "Or not. Think positively! Perhaps they are just lonely and want company!" He suggested, a smile on his face as he turned to the door Ruri had walked through, sonicing it.

"Like you?" Rennarni asked, causing the Doctor to stop smiling.

"Yes. Like me." He said hesitantly and quietly. "Difference is, I don't abduct people. Although, there was a couple of times where they might say I did... But it was usually by accident." He rambled, unlocking the door to the market. "Here we go..." He put the sonic back in his pocket. "So, coming?" He turned back to Rennarni who shook his head.

"No. We will get taken." He stated, stepping back.

"Fine! Stay here. I'll find everyone." The Doctor slightly huffed as he entered the room, the door shutting behind him. "Now what..." He muttered to himself. "Hello?" He called out, walking forwards. "Anyone seen my friend? Human?" He spun round, seeing something out the corner of his eye. "Hello..." He called again, a bit quieter. Someone stepped out of the shadows, they were wearing a white robe with a hood, covering their face.

"You're gambling a bit. Want to get caught or something?" The person spoke, a female voice.

"Yes. See, whatever is here has taken my friend. And I intend on getting her back." He said firmly.

"Well, you're going to need a lot of help with that." The woman took off her hood, revealing her face. Her skin was a deep green, with patterns. "The Doctor and the TARDIS."

"Who are you?" He stepped forward, narrowing his eyes.

"A friend."

"No. Who are you?"

"My name is Zariana. But call me Zara - I insist." She held out her hand for him to shake, but he declined her offer, not trusting her yet.

"Where is Ruri?"

"She is above."

"Yes, I've got that bit. But where?" He paced round, looking at the market stalls that were all shut up.

"I don't know. Just above." Zara had a small smirk on her lips.

"How do I get up there?" He asked.

"I can take you. I can help." She strode towards him. "I promise I will get your friend back to you, whatever it takes." She spoke in a quiet and serious tone, her smirk gone.

"Then let's go."
