"Doctor?" Rose called out as she walked into his bedroom on the TARDIS. "Are you in here?"
A loud squeal sounded from the attached en suite, "Rose! Don't come in here!"
"What? Why?" Rose asked with a smile heading in the direction of his voice.
"Just don't! I'm, erm, I'm naked!"
"Oh? Well then I'm definitely gonna come in," Rose smirked.
"Rose!" the Doctor squeaked. "That's not funny!"
"Oh come on, Doctor," Rose leaned against the bathroom door. "Are you really naked?"
"Well, no," the Doctor's voice was muffled. "But still don't come in!"
"Why? What're you doing in there?"
"Nothing."
"Doctor... you're not, erm, I didn't think Time Lords even-"
"No! Goodness, Rose, do you have a foul mind," the Doctor sounded like he was smiling.
"Then what are you doing?" Rose called to him.
"I'm sitting."
"Sitting."
"Yes."
"Just sitting?"
"Yes, we established that. On the floor."
"And why are you just sitting?"
"Because I feel like it."
"Of course you do," Rose rolled her eyes. "Well, if you're just sitting, then why can't I come in?"
"Because sitting as a sport is very hard to do and requires concentration which is best done in aloneness," the Doctor drawled.
"Oh, shut up," Rose reached around and turned the door handle. "I'm coming in, whether you like it or not."
"No, wait! Don't!"
Rose walked in and immediately stopped in her tracks. Her mouth gaped as she stared at the sight of the Time Lord in front of her. He was sitting cross-legged on the tiled floor with his hands up in warning and a horrified expression on his face. Scattered around him were various bottles and on his head was a loosely wrapped towel.
"I said don't come in!" the Doctor covered his face with his arms. "Don't look at me!"
"Doctor?!" Rose bit back a laugh as she crouched down in front of him. "What? What's that on your head?"
"A towel," the Doctor still wouldn't look at her. "Now go away."
Rose looked around and picked up one of the bottles lying beside them.
"Ginger Galore - Get the color you've always desired?" Rose read the label while hiding her giggles. "Oh my god. Doctor... did you dye your hair?"
He was silent for a bit before mumbling, "Maybe."
Rose bit her lip to keep from laughing.
"I've always wanted to be ginger," the Doctor peeked out from between his crossed arms.
"Can I see then?" Rose asked with a smile.
"No," the Doctor squeaked and disappeared behind his arms again.
"Why not?"
"Because. It's, it's not done yet."
"Really? Then what would happen if I just-"
Rose lunged forward and grabbed the towel, pulling it off the Time Lord's head. He reacted with an unflattering screech and scrambled away covering his hair. A laugh escaped Rose's lips when she saw him and she quickly covered her mouth.
Instead of a ginger color, the Doctor's hair was a bright pink.
"Your hair!" Rose couldn't help herself but let out a snicker. "It's-It's-"
"I know," the Doctor sobbed. "I look horrible."
"What did you do?" Rose laughed.
"How was I supposed to know how my hair was going to react?" the Doctor hid his face in his hands, his pink hair shaking. "It's gonna take weeks to get this washed out!"
"Well maybe you should have thought of that before you put that stuff in your hair," Rose giggled.
The Doctor moaned and covered his whole head again, curling up into a ball. He looked absolutely miserable.
"I'm going to die," he whined.
"Oh, come on," Rose said. "It's not that bad."
"Yes it is."
"Doctor," Rose reached out and put her hands on his shoulders. "It's just pink hair. What's wrong with pink?"
"It's pink, Rose," he looked up to her with a frown.
"So?" Rose smiled. "I wear pink all the time."
"Yeah, but you look good in pink," he said. "All pink and yellow."
"Well, you don't look half bad with pink hair," she smiled. "It's cute."
"Cute?!" he squeaked indigently. "I'm the Oncoming Storm, the Last of the Time Lords! I'm not supposed to be cute!"
"Well, you are cute," Rose giggled and reached a hand out to ruffle his pink hair. "You've always been cute, and there's nothing you can do about it."
He batted her hand away and covered his top with his arms again.
"Well, I don't want to be cute."
"Then you're gonna have to regenerate into something uglier," Rose said playfully.
"There's a thought," the Doctor's face seemed to brighten.
"What? No!" Rose quickly said. "No, I was joking, Doctor! Don't you dare regenerate. I've only just gotten used to this cute regeneration."
"It's not a cute regeneration," he pouted. "And neither is this bloody hair. Maybe I should just shave it off."
"And then you'd have a pink head." Rose gave him her tongue-in-teeth grin and stood up from the floor, "Do you want me to help you wash it out?"
"I've already washed it three times," he whined.
"Well, I know some cheat codes to washing out color," Rose smiled. "I dyed my hair green once, and me and Shareen found some cures to getting it back to its normal color."
"You had green hair?" The Doctor came out from behind his arm wall once more.
"Yup. Even more unflattering than your cute pink."
"All pink and green, Rose Tyler?" he smiled.
"Yes," she rolled her eyes and then extended him her hand. "So? Do you want my help or not?"
He hesitated for a bit. Then he gradually took her hand and let her haul him up.
"Fine," he grunted. "But you better not dye it green."
"Wouldn't dream of it," she smiled as she gave his hair another ruffle.
