Rose had taken Mickey on a tour of the TARDIS but lost him in the room with soccer playing on the TV, so she retreated into the library.
“So, are we going to talk about why you were lying through your teeth?” Rose looked up from her spot on the couch. The Doctor was in the console room and Mickey was off somewhere watching soccer, so the only person who could’ve been speaking was…
“Well?” Lilith said, plopping down next to the girl. “We both know you were.”
“No reason,” Rose said vaguely. “Why’d you agree?”
“I didn’t, I just said that he’d be company. But we’re not talking about me, we’re talking about you.”
Rose sighed. “I like it when it’s just the three of us, you, the Doctor, and me. Because honestly, you don’t get in the way of whatever the Doctor and I have. Sure you mock us constantly, but your not interested in me. Not like Mickey is, anyway.”
“You think Micks’ feelings for you will get in the way of whatever you have with the Doctor?” Lilith guessed.
Rose nodded. “It sounds daft.”
“No, it doesn’t. But you won’t have to worry. The Doctor will mark his territory eventually and Mickey will have to remember to— oh, how did Jack put it? — keep his hands off the blond.
“Mark his territory, huh?” Rose repeated, lifting an eyebrow.
“Maybe give you a hickey, too.” Lilith shrugged. “How am I supposed to know what you two get up to when he crawls into your bed every other night?”
Rose blushed furiously. “We don’t do anything. He just stays with me.”
“Right. And I am supposed to believe you because…?”
“Lilith!” Rose hit her with her book.
Lilith laughed loudly. “Alright, alright, I’m done. See you around, Tyler.”
The Doctor was under the console, fixing whatever was preventing the TARDIS from landing properly.
“So—” Lilith began.
“No,” the Doctor said.
“But I didn’t say anything!”
“I am not talking about my relationship with Rose right now.”
Lilith crossed her arms. “Because you let Mickey join on to but a barrier between you two?” she accused. The Doctor stayed silent. “Oh, don’t pretend I’m wrong.”
“Why are you so insistent that Rose and I become a couple, hm?” the Doctor demanded. “What’s it to you?”
“You’re family and she’s my friend and I want you two to be happy,” Lilith said simply. “She makes you happy and you make her happy.”
“And we can’t make each other happy as best mates?”
“Best mates, as you put it, don’t act like a couple or kiss.”
“I’ve only kissed her twice!” the Doctor protested.
“Four times,” Lilith corrected. “Once to take the vortex out of her, once under the mistletoe, once on New Years Eve, and once on New Earth.”
“That last one doesn’t count,” the Doctor said.
“But the New Years kiss should count as two.” Lilith countered
He blushed just as deeply as Rose had and muttered something about wine before disappearing under the console again. Lilith lay on her stomach and looked down into the gaping hole in the grating. “Go away, Lilith.”
“I’m just saying that inviting Mickey on board wasn’t your most genius idea if you want to pursue—”
“Go away, Lilith.”
“Fine, fine,” Lilith gave in. “But I’m not done with you, Time Lord.”
She wasn’t done with either of them.
