Explosion
Once inside the TARDIS, Sadie headed immediately for her room, mostly to have another look at her brand new book, but partly to get away from the Doctor, as well. He could talk for hours about positively nothing at all. Sometimes it wasn't so bad, but at times it nearly drove Sadie insane. She often wondered if he talked just to hear himself. It was a very likely possibility.
She headed down the hallways, navigating them almost expertly. Twice she took wrong turns and had to go back. But she was learning. After her experience of being lost that one time, she'd asked the Doctor to at least map out where the most important places were, but he'd laughed off the suggestion, telling her she'd learn her way around in no time. For the most part, he'd been right, but a map would have come in extremely handy.
Sadie finally reached her room, pushing the door closed behind her, brimming with excitement. She sat down cross-legged on the bed, her bag in front of her. She reached for it, and noticed her hands were slightly trembling. That made her laugh.
"Well, that settles it," she said to herself. "I'm officially the biggest nerd in all of nerd-dom, to be this excited over a book." She sighed and shook herself. "Get a grip, Sadie."
She undid the flap on her bag and reached inside, feeling around until her fingers hit on the cool, slick cover. She grasped the book and pulled it out onto her lap. She tossed the bag to the floor beside her bed. It landed on its side, contents spilling out. Sadie paid it no attention, however.
She ran her fingers over the cover of the book, once again noting how spectacularly creepy the cover was. The glowing eyes seemed even brighter now. She shivered, just like she had in the shop. She eagerly opened the book to the first page, which was marked "Introduction". Her eyes eagerly searched for the first line, but right as they found it, a loud sound from elsewhere in the TARDIS made her jump. The book fell from her hands and slammed closed, landing on the quilt covering her bed.
She reached for the book again, but just as her hand closed on it, the Doctor began to shout and curse loudly. Apparently something hadn't gone as planned. Which seemed to happen quite often, actually. Sadie sighed deeply and rolled off the bed.
"Better go see what's up," she said aloud, tugging at the bottom of her shirt before heading for the door. The book was left lying on the bed.
As soon as Sadie had left the room, the eyes on the cover began to glow brighter and brighter. A soft, gruff chuckle echoed around the room before a deep voice spoke.
"Next time."
Sadie made her way through the halls once again, finally reaching the console room. The Doctor was hopping around like a madman, still cursing. The console was shooting sparks wildly.
"What did you do?!" Sadie exclaimed, making sure to keep herself well away from the sparks.
"I don't know!" The Doctor replied. "But I can't seem to un-do it!"
"Well you'd better figure it out before you blow us to smithereens!"
"I'm trying!"
The Doctor pulled levers, flipped switches, smacked the console with a sledgehammer, and did all other sorts of things to try to stop the sparks. Finally, he found the right combination of movements and the sparks ceased.
"I swear, one of these days you're going to do something wrong and blow us to bits…or worse," Sadie remarked. The Doctor looked offended.
"Never. I know what I'm doing," he said, defensively. Sadie smirked.
"Sure you do," she answered, turning to head back out. "Try not to catch yourself on fire, okay?" The Doctor chose to ignore her. Sadie began making her way back to her room, anxious to begin reading her mysterious new book.
