"Liza, for the last time, the screen isn't my secret diary!" The Doctor pulled the screen away from me (again) as I reached for it for the 4.5 billionth time.

"Why?" I ran behind him as he pulled the screen around, running around the console. "Is it some sort of a secret plan to overthrow the emperor of Tivoli?"

"Tivoli gets a new emperor every week! And no, it isn't a secret plan or anything!"

"I don't know, maybe you're planning to start a new reign or something-"

"And why would I do that?" He stopped and looked at me, raising an eyebrow.

"Um-" I stopped and bit my lip, "Because you like Tivoli?"

He closed his eyes and shook his head, sighing. "Why do you have to come up with the world's strangest explanations for everything?"

I threw my hands up and placed them on the edge of the console. "I don't know, maybe because I have no idea what the actual answer to your question is!"

He rolled his eyes and pressed a few buttons on the TARDIS. "I swear it's a miracle I've not gone completely insane yet," He muttered, and I rolled my eyes at him. "That's because you were always insane,"

He pretended to not have heard that (I knew he did- he was able to hear me talk to Rose about the location of the cookie jar a whole corridor away just to prevent me from stealing his 'secret' stash of cookies three weeks ago) as he turned to the corridor. "Rose, where are you?"

"Hang on!" Her voice was muffled. Soon, she ran toward us, holding a hat (more specifically, a stetson). She came to a stop at the entrance of the console room and spun around, putting the hat on. "How do I look?"

She was wearing a miniskirt with stockings and a blue top, complete with her hair tucked under her hat. "Like Liz Shaw, except with longer hair," I said, and she raised an eyebrow. "Who?"

"I'd lose the hat if I were you." The Doctor walked back around the console. Rose frowned at him. "But I want to wear a hat! And I only had another option in the closet for a hat!"

"Go with that then!" He shrugged, and she scowled, "With what, the red fez nobody likes?"

"Go with the fez, fezzes are cool." I said, and the Doctor and Rose looked at me, both eyebrows raised.

"Fezzes? Cool? What in the name of everything are you going on about?" The Doctor looked scandalised, and I put a hand on my heart, "God, don't say that, fezzes are cool."

"No they're not!" Rose said, walking toward us. The Doctor nodded at her. "Exactly!"

"Future you would like to have a word," I muttered, putting my hand on the console. "Anyway, where are we going?"

He looked up at me, a grin on his face. "That's a surprise."

I groaned. "Please don't tell me we're going to that steam engine exhibition you were talking about-"

"Or the intergalactic collection of spoons-" Rose continued, leaning forward.

"Or the stamp museum on that asteroid, er, what was it called?"

"I think it was some sort of, er, Blonky-"

"Blomatrix!" The Doctor looked around at the two of us, clearly offended. "And stamps are interesting, for your kind information!"

"Yeah, okay, okay-" I put my hands up and turned toward the console. Rose turned toward me, "Yeah, Doctor, they're fascinating-" I flashed her a grin and she grinned back at me for a moment, before looking back at the Doctor, who was scowling at the two of us. Rose and I had gotten closer in the last few weeks, and honestly speaking, she wasn't as bad as I thought she would've been. I wasn't a huge fan of her while watching the show, but she wasn't as horrible as I assumed her to be.

"Do the two of you only get along when it's time to bully me?" He looked at the two of us and back at the console, "Anyway, to answer your previous question, we aren't going to any of the places you both have mentioned-" And then he grumbled a bunch of indecipherable nonsense- "Anyway, like I said, you both aren't going to be expecting this!"

"Um, okay?" I looked at him, my eyebrows raised. "It better not be the planet full of carnivorous pears."

"There is no planet of carnivorous pears! And even if there was, that would be the last place we'd go to!"

"You say that every time we talk about a dangerous planet and we always end up going there!" Rose said, walking behind him as he walked around the console, flicking switches and pressing buttons.

"Yeah, but he's got a phobia of pears because they're squishy and make your chin wet," I muttered, and scowled at him as he pushed my hand away when I tried to press a button.

"I haven't got a phobia of pears, just a strong dislike for them, and no, we aren't going there," He turned to me and pointed to a lever beside me. I pulled it and we took off, just as violently as we always did.

"Doctor, honestly, for once in your entire life," I slowly got up from the floor of the TARDIS, my head spinning. I put my hands on the console and stood up, blowing a strand of hair away from my face (only to fail terribly as it fell back on the exact same spot again), "And I mean it in every way possible- can you not almost get everyone killed every time you fly the TARDIS?"

He scowled at me and threw his hands up in the air, "It's called quality TARDIS driving!"

"No, it's called 'Hey, I'm going to get everyone maimed or killed!' TARDIS driving!" I pushed my hair back and scowled at him as Rose laughed and the TARDIS hummed, amused, a yellow glow coming from her for a moment.

"Whatever Liza says though, I like it," Rose shrugged and the Doctor grinned at her. "See? At least someone accepts that it's quality TARDIS driving,"

I frowned and leaned against the console, "She said that she liked it, she didn't say that it was quality TARDIS driving or whatever,"

"Anyway, where are we, Doctor?" Rose cleared her throat and smiled at him. He grinned at the two of us, "Finally, somebody asked! You'll find out once we walk outside!"

I skipped down and was about to open the door when he shouted and I jumped, "What the hell do you think you're doing?!"

I turned around and frowned, "Going outside to see where we are! You said that we would find out when we walk outside!"

"What, like that? You'll die of hypothermia the moment you walk out!" My eyes widened and I ran back toward the console as Rose gasped and almost fell down. The Doctor then shook his head, "Actually, you'd die of oxygen before that-"

"What?!" Rose yelled, and I gripped onto the console. I looked up at him, "Seriously, what the hell, Doctor?"

"You'll have to wear spacesuits, of course! They're in the closet!"

"What about you then?" Rose scowled at him, "Or can Time Lords survive oxygen deprivation?"

"I have one in my room, for your kind information, and I'm going to go put that on, so stop asking questions and go put your spacesuits on!" He walked through the corridor as the TARDIS hummed again, exasperated this time. I patted her console, "Yeah, I know, Sexy,"

I looked up at Rose, who had a weird look on her face, "Sexy?" I shrugged, "Yeah, that's her name,"

"Of all the names in all of time and space, he picked Sexy," Rose shook her head and I grinned. "Well, he doesn't even realise that she accepted that as her name till she tells him herself,"

Rose looked at me, an eyebrow raised and I laughed, "Spoilers," I stood up straight and stretched my arms, "Anyway, why don't we go and put our spacesuits on before the Doctor starts complaining about slow apes or whatever?"

"There you are! I've been waiting for hours!" The Doctor stood near the console, wearing a bright orange suit, holding a helmet. The TARDIS hummed, sending a red glow throughout.

"I don't speak TARDIS, but I'll take that as her saying that you didn't wait for hours," I put the helmet on and blinked as everything in front of me was tinted in a bluish colour. The TARDIS sent a wave of green light and I smirked.

"I'll take that as the TARDIS agreeing with Liza," Rose put on her helmet, twisting it to hold it in place. The Doctor scowled at us and at the TARDIS, "You're supposed to be supporting me!"

She hummed again, sounding like she was laughing. I grinned at her and turned to the Doctor. "Anyway, at least now that we look like Human slash Time Lord Cheetos, can you tell us where we are?"

He grinned at us and pointed to the door, "Why don't you see for yourself?"

I raised my eyebrows at him, "Okay, but are you sure we're not gonna die this time? You literally just scared us with hypothermia some time ago,"

"Why don't you tell that to Rose?" He pointed at the door and I turned around. It was open, and Rose wasn't there. "Rose, are you okay?" I called out.

"Oh my God! Liza, you should really come and see this!" I turned back to the Doctor, who pointed at the door. I took a deep breath and looked at him, "I swear if I run into some sort of space Yeti that isn't friendly, I'll kill you,"

I turned around and walked outside slowly, taking deep breaths as I did so. I gripped onto the door frame of the TARDIS as I slowly stepped out, my heart beating fast against my chest.

I looked around at my surroundings, mainly the thing in front of me, and I gasped, "You have got to be kidding me," I slowly stepped forward to go and join Rose, who was staring at the bluish orange atmosphere. "We're on a planet. An actual planet. A planet that isn't Earth,"

We had gone to visit Democritus in Ancient Greece after the whole Satellite Five incident, and then we went to meet Jackie, after which we drifted around in space for a while. This was the first time the Doctor took me and Rose to another planet, and a planet that was uninhabitable, by the looks of it.

"Moon, not planet," The Doctor came to stand beside me as I looked at the sky. I looked down at the ground, which was covered with powdery stuff and was hard underneath. I was about to step forward to go and meet Rose when the Doctor put a hand on my shoulder. I looked at him. "You might want to be careful while walking on the ground,"

I nodded and slowly put a foot forward and grabbed onto the Doctor's arm in shock as I slipped. The powdery stuff was swept away as my boot had penetrated it, only to leave a smooth and hard surface, which was a tad bit slippery. "The ground, it's- it's made of ice,"

He nodded and grinned, "You're gonna have to be careful then. No walking without paying attention," I nodded and let go of his arm as I slowly regained balance and put my foot on the ground slowly. I slid my other foot forward, stretching my hands out. I closed my eyes and slid my feet forward, skating slowly toward Rose.

It took a while, but I finally reached Rose and stared at what she was looking at. There was a brown object in the sky, far away from us. It took an effort to see it as it was completely blocked over by the thick atmosphere of wherever we were.

I craned my neck and squinted to have a better look at the object. As I finally got used to the atmosphere, I was able to see everything in the sky more clearly. I gasped as I could slowly see translucent rings surrounding the planetary object in front of us.

The Doctor finally caught up with us and put an arm around me and Rose. "That's Saturn, isn't it?" Rose whispered, and the Doctor said, "Yup! That's Saturn- second largest planet in your solar system. Huge gas giant, rings made of ice- all that."

"So we're on one of its moons." I said, looking away from Saturn and at the rest of the landscape. We weren't very far from the TARDIS. The whole horizon was full of huge mountains which were topped with ice. There were smaller hills around, and we were near a massive water (or some liquid) body which looked like a massive lake.

I turned to the Doctor again, who nodded. "We're on Titan. Saturn's largest moon. The crust is made of solid ice." He then pointed to the lake nearby, "And that lake over there, and all lakes on the moon- they're full of liquid methane and ethane- basically liquid rocket fuel."

"So- nobody lives here?"

"Rose, if anybody ever lived here, they'd either be frozen or exploded, or really resistant to cold and oxygen deprivation," He replied, and I smiled. "Anyway, I brought you both here to go and see that volcano over there," He pointed at the mountain nearest to us. "It's about to erupt, and I just realised that neither of you have ever seen a volcano before,"

"You realised we've never seen volcanoes before, so you decided to get us to Saturn's moon."

"Come on, Liza, go big or go home- or in this case, go back into the TARDIS."

"So basically, go big or go bigger on the inside."

"I'd choose bigger on the inside any day," Rose said, and the Doctor scowled at the two of us, "Should've never said that."

I laughed and slipped- and gripped on his arm as I did so and he stuck his tongue out at me- only to fail and have it bump into the helmet instead. Rose and I laughed, me slipping more, but thankfully, the Doctor had a grip on me and I didn't fall flat on my helmet onto the ice.

"Anyway, now that Miss Clumsy isn't falling anymore, let's all go and see the volcano= from a safe distance, of course. Spacesuits don't suddenly turn you into an Avenger."

"A what?" Rose asked, and I looked at him, eyes wide. "You know about the Avengers?"

"Yeah. Almost cried during Endgame-"

"Oi- spoilers- it hasn't been released in my world yet." I held up a hand as I slowly tried to regain balance and stand properly.

"What's an Avenger?" Rose scowled at the two of us, clearly not happy that she wasn't involved in the conversation. The Doctor turned to her and said, "Well, they're a band of superheroes who try to save the world from threats. The one time they tried to stop an alien threat, though, pathetic. Although, that's what you expect from apes."

I looked up at him. "Excuse me?"

Rose shook her head. "You'll end up getting used to all the ape comments someday. He loves insulting species when he's aggravated, honestly,"

"Oi!"

"Alright then, this dune is the nearest we can get to the volcano without there being a high chance of us getting a huge jet of cold water on us-"

"Whoa, whoa, whoa, hold on-" I held up a hand a little way from the Doctor, who was standing on the top of the dune with Rose as I was climbing it. "What do you mean, cold water?"

"You know, the cold water from the volcano!"

Rose whipped around and almost hit the Doctor by accident, "Don't volcanoes have lava and fire in them? Why is there cold water in a volcano?"

"Moon this cold, planet this far from the sun, atmosphere like this, crust made completely of ice- isn't it obvious? Also, hurry up, Liza, or you'll miss it,"

"Okay, okay, I'll get there, hold on!" I trudged up the dune, holding my hands out and walking like a penguin. I finally reached the Doctor and Rose and went to stand in between the two of them.

"Took you long enough," The Doctor grumbled, and I scowled at him. He then pointed to the volcano. "Don't look at me, look at the volcano, it's starting to erupt,"

I looked toward the volcano, from which a huge rumbling sound was heard. "Okay, this will take some time, but it will erupt soon, if I've remembered the dates correctly."

"Please don't tell me we landed in the wrong time zone again because if we did, I would definitely be extremely irritated."

"Would it kill you to have a little faith in me?"

"Will the two of you stop arguing and watch the volcano for god's sake?" The Doctor and I looked at Rose, who was scowling at the two of us. I shrugged and threw my hands up. The Doctor looked back at the volcano, which seemed to be cracking slowly. "Both of you- the volcano will take a shorter amount of time to erupt than it will on Earth, mainly since I decided to come here during a time when the seismic activity is at an all time high,"

Another huge rumble. There were a few cracks on the volcano, which were slowly starting to get wider.

"If my watch is right, we've got about a few minutes till the volcano erupts, which is just as well, because the TARDIS oxygen field will run out soon, mainly since I've extended it this far,"

The volcano was cracking more and there were rumbling noises coming from it more often as something leaked out of it slowly. I looked behind to see the TARDIS, which was close to us, probably because we were on the closest dune. "How long will it last?"

The Doctor shrugged, "About an hour. Just enough time for us to watch the eruption and go back as soon as possible."

I looked back at the volcano, shuddering. Some time later, the volcano started rumbling louder. The Doctor took mine and Rose's hands and squeezed mine. "It's happening."

My heart started beating fast as the rumbling started to get even louder. I squeezed his hand and he tightened his grip on mine as I bit my lip. The liquid in the volcano was leaking more and more and was forming streams from the top of it. The streams were becoming more and more profuse and fast, and the rumbling became louder.

I took a deep breath and dug my teeth into my lip as the explosion reached my ears. And then, the huge jet of cold water spewing from the volcano. The massive jet that surprisingly didn't reach us (probably because the dune we were on was kinda far away from it). It fell into the methane lakes and had a lot of white mist spewing out.

I gripped my mug of hot cocoa with one hand as I went into the console room. The Doctor was there, fixing something as usual, and I smiled at him. "Want some hot cocoa?" I held out the other mug as he looked up from whatever the hell he was doing. "Alright!" He walked toward me and took the blue mug with the bananas all over it. "Where's Rose?"

"Jackie called. She's talking to her right now." I walked toward the console, "Anyway, what are you doing?"

"Nothing, just fixing some stuff that's been broken."

"Seriously, though, why is it that every time I come here, you're fixing the TARDIS?"

"Because she keeps getting damaged thanks to whatever nonsense we get ourselves into!"

"Really?" I raised my eyebrows at him. He shook his head as he gripped the hot cocoa and pointed to the door. "Yes, really. Also, go look outside. Thought you might like where we are. And don't step out without looking."

I shot him a look before going toward the door to see where we were. I carefully opened the door (like he said) and gasped at what I saw. I looked back inside at him as he had an expectant smile on his face. "Well?"

"We're hovering on top of Saturn. Like, the actual Saturn," I whispered, and sat down on the edge of the TARDIS. The planet below me was huge- and it's translucent rings were much clearer now that we weren't on a moon with a thick atmosphere. The colourful rings and the planet almost dimmed all the other planetary bodies and the stars in the distance.

I took a sip of my hot cocoa after blowing in my mug to cool it down a little. I turned around to the Doctor, who was looking at the console, his mug on the floor. "Hey, big ears,"

He looked up from his work and scowled at me. "They're not that bad,"

"I don't care- anyway, come here,"

"I can't, I'm fixing the TARDIS," He pointed to the console and I rolled my eyes. "That can wait, you really need to interact with other people and that's more important at the moment- God, I sound like Alice." The Doctor was smiling at me. I raised my hand, "But the point still stands."

He raised an eyebrow at me and I shook my head. He then stood up and took his mug in his hand. "Alright then. Human interaction it is."

A/N: Hey guys! I know, nothing really happened in this chapter and it was probably really boring, but the next one is gonna be Father's Day (another episode I wasn't particularly a huge fan of) and I think another original chapter, but an adventure instead. Thank you all so much for showing so much love to the story and please let me know all your thoughts about Liza and this chapter in the comments!
