A/N: Writer's block is not my friend.

Clara and the War Doctor stepped out of the TARDIS. "Who's here?"

The Doctor gestured. "Her."

Across the room, a little girl stood there, talking to the Woman. Her blond hair and dress were quite dirty, as if she had been running from something.

Clara frowned. "Who's that?"

The Doctor ran his hands through his already-crazy hair. He looked like he had just stepped out of the shower. His shirt was crumpled, as if he had just thrown it on. "She's a little girl we met in the park the other day when you went shopping. River found her outside."

"…and there was a big scary red man chasing me!" The little girl was saying.

Ten leaned in close to the Woman's ear. "We should be careful. She may be a Zygon to!"

She glared at him. "Don't be silly! How would the Zygons find us in the first place? Besides, she's just a little girl."

"That's what I'm afraid of."

She rolled her eyes in exasperation. "Come on, dear. Let's get you cleaned up."

The War Doctor watched as the Woman took the girl into the bathroom. "Why were the Zygons chasing her in the first place?"

"The Zygons want to deceive me." The Doctor muttered, looking after them. "I guess they're trying to chase down anyone that they deem capable of maintaining my trust, and they tried to catch that little girl, if that really is her."

Clara looked at him. "Then why are you letting her in here if you think she might be a Zygon?"

"Because I can't be sure she's not just human. I'll keep a close eye on her, though."

Ten walked up to them, clasping his hands together. "Well, now that that's settled, I'll go-"

Clara stopped him before he spoke further. "You're not going anywhere! Now that you've had a shower, you and you…" She pointed at the Doctor. "…are going to clean up this floor!"

Ten stared at her. "What?"

"What about the Master?" The Doctor fussed.

She looked around. "I don't see him anywhere, and also, he's my fiancée, so he is exempt."

"What about him?" Ten stabbed a finger in the War Doctor's direction.

She glared at him challengingly. "He didn't walk all over my good carpet with dust feet and clothes, because he actually has sense."

Later, the Doctor stepped into the TARDIS, now more disheveled than ever after having to clean Clara's floor. He heard noise echoing from somewhere inside the machine. He guessed it must be the Master.

The Master had been tugging away for hours.

He had felt a slightly loose area in his trap around his left arm, and was currently trying to pull it free from the pink slime. He was urged on by his three cellmates, as McGillop had woken up a few hours prior to the discovery. It seemed to be getting loser by the second.

The Doctor rounded a corner, and saw that it was the Master who was the source of the noise. He was tinkering with some little random contraption, sending the metallic clinks through the silent TARDIS. His hair was wild, as if he had just gotten out of the shower, and his clothes were quite rumpled. If he heard the Doctor approach, he did not acknowledge him.

The Master leaned his head back against the wall, sighing in despair. His efforts had proved unsuccessful, because where there was one loose strand, there was always a strong one to take its place. There seemed no point in trying anymore.

The Doctor opened his mouth to say something to the Master, but before he could, something happened.

Just for one second, an instant, so fast that he wasn't even sure if he saw it, the Master's appearance flickered from normal to that of the Zygon/human hybrid, his skin turning red and bearing the suction cups that the others had. Before he could register what had happened, it was gone, and the Master's appearance returned to normal.

The blond Time Lord carried on with his work undisturbed, seemingly unaware of this change or the Doctor's presence.

The Doctor blinked, unsure of what had just happened. He wasn't even sure if he had just seen that. He backed away from the door and the Master, turning and tearing off down the corridor.

Clara sat on the couch with her laptop. A sigh escaped her lips, and she ran her fingers through her hair in mild agitation.

Ten lay outstretched on the floor, relaxing after a hard bout of carpet cleaning. The Woman had gone out in search of some better clothes for the girl, leaving her in the care of the War Doctor, who she deemed the most suitable out of the three incarnations to take care of her. Now they were off somewhere else in the flat, probably playing some sort of game.

River stepped over Ten, taking a seat beside Clara. "Anything the matter?"

"No." Clara murmured. "It's just difficult to plan a wedding with everything going on, especially in a week. I mean, first we have shape-shifting monsters invading the planet and bent on killing the Doctor, and then the three Doctors, and now we have a little girl that's most likely separated from her parents by the monsters. I honestly don't know how many more people my flat can hold. It's only supposed to house two people in the first place."

River smiled. "It's not supposed to be easy when you deal with the Doctor, but don't worry. We'll get things sorted out eventually. Hey, do you want to go over to St. John's tomorrow? We haven't checked that place out yet."

"I see no reason why not."

"I honestly don't know what you see in him." Ten sighed from his position on the floor. "He's the most arrogant, pompous, murderous, insane-"

"Oi!" River nudged his arm with her foot. "Like you've never been in love before. Besides, you'll understand once you get to the point where the current Doctor is."

"I hope so, because I-"

He was cut off as the TARDIS doors opened and the Doctor ran out at full speed. He tripped over his past self and fell, arms flapping comically, straight into River's lap.

"Where are you going in such a hurry?" River asked, looking down in amusement at her husband.

The Doctor scrambled upright, dusting himself off furiously, trying and failing miserably to hide his blush. "I think the Master is a Zygon!"

Ten twisted his head around, looking up at him in confusion. "Huh?"

"I think I saw him… Well, I don't think, I know that I saw him briefly change into the appearance of a Zygon hybrid! It was only for a moment, but I'm pretty sure I saw his form change and his skin turn red! I think…" He pointed wildly at the blue box, sputtering. "He's in there!"

Clara cracked a small smile. "Doctor, you're not making a lot of sense."

River shook her head. "When was the last time you had a good, proper sleep?"

"Two months ago!" The Doctor waved his hands. "Anyway, it doesn't matter. I know what I saw, or at least I think I do…"

"Well, if it was a Zygon, wouldn't it have tried to kill you by now?" Ten asked.

"No!" He leered down at him. "Maybe. I don't know!"

"If only I had my ding machine." He sighed ruefully. "Then we could tell."

"Well that's what you get for throwing it at a Zygon's head!"

"What else were we supposed to do?"

"I could've-"

"He does have a point, Doctor." River interrupted the argument. "If it was an actual Zygon, it probably would've tried to attack you by now. You know how fast the others were to attack you at the Undergallery and in the 1500s. I think you're just tired, and need some real sleep."

He rubbed his forehead. "Fine." He looked down at his past incarnation on the floor. "Could you try and make another ding machine, just to be safe?"

"Sure, but it won't be on the fly."

"Good." He glanced at Clara. "You don't think I've gone insane, have you? I hope I haven't made you mad by calling your husband a monster."

She cocked her head. "Not yet. Don't worry about it. By the way, he's not my husband yet."

"Right…" He muttered, and he vanished into the TARDIS.

Clara looked at River. "Should I be concerned?"

She shook her head. "I wouldn't worry about. He gets like that every now and then. He just needs some sleep and he'll be back to normal."

"Oh!" Ten gasped from the floor. "The 1500s! I forgot to marry Elizabeth when we were there!" He started to sit up, but gave up and flopped down again. "Eh, I'll do it tomorrow."

River opened her mouth to object to the proceedings, but remembered who she was speaking to and held her silence. Clara noticed this and couldn't withhold a giggle at her expense.

The blond nudged her. "Shut up."

The Doctor stepped into the TARDIS to find the Master standing at the console, fiddling with it. The blond Time Lord looked up to see the Doctor staring at him.

He scowled. "What are you looking at?"

The Doctor looked away swiftly. "Nothing. I just need some sleep."

"Good luck."

The Doctor walked through the halls of the TARDIS, battling with his mind. Maybe River was right when she said he was just seeing things, but he couldn't be sure. He couldn't shake the feeling that something was terribly wrong.
