A/N: Since life is getting in the way, I won't be getting chapters finished and posted for my other fics like I had hoped. So enjoy this one-shot while I get things straightened out and hopefully I'll be able to post chapters soon.
When a Fangirl Attacks
"Why don't you ask her yourself?" Donna asked, a warm smile on her face. The Doctor turned around, stunned to find that Rose was standing some distance away up the street. Rose started running towards him, a huge grin on her face. The Doctor did the same, not noticing the Dalek roll up moments later.
"EXTERMINATE!" it shouted, before a bright flash of light lit up the area. A portal had formed across the street.
Yeahhhhh!" a figure shouted as she ran out of the portal and towards the Dalek, wielding a Baseball bat. She started beating the Dalek with it as Jack transmatted in.
"What's with the blonde?" Jack asked Donna as they all stared in confusion.
"Well, I'm Lilli and I'm here to fix a few things. Ok Jack, you can use that big gun of yours now." Jack frowned, wondering how she knew his name as he did what she said and fired at the Dalek. The top of it exploded, a look of satisfaction on Lilli's face.
"Ok, good. You might want to get to the TARDIS now, you've got planets to save. Though now that I think about it, you might want to finish that conversation you had at Bad Wolf Bay, Doctor."
"Who are you?" the Doctor asked, a deep frown set into his face.
"I'm a fangirl from another universe, and that's all you need to know." Lilli explained before glancing down at what looked like a watch.
"Oh. Time's running out, you might want to hurry up!" Deciding it would be best to follow Lilli's advice, the Doctor turned to Rose and took her hand.
"Rose, I'm sorry I didn't get to say this before; but, I love you." Rose smiled at the Doctor's statement before sharing a kiss. They broke the kiss moments later and glanced sideways at Lilli, who was applauding. She stopped when she realized they were staring at her.
"OH, sorry, ruining the moment. Uh, I'd better be going." Lilli said before pressing a button on her watch, making the portal reappear.
"Well, have fun storming the Crucible. Oh, and Donna, you might want to stay away from the Doctor's severed hand. Buh-bye!" Lilli said, then ran at the portal, holding the Baseball bat over her head. A slight look of confusion spread across everyone's face before they shrugged it off and headed for the TARDIS.
