The Doctor held her breath as Lucifer walked past the door. She was hiding in Rose's room, in the closet filled with colorful clothing. The Doctor felt weird doing this, but it was the only thing she could do right now. The TARDIS was redirecting Lucifer, but he kept getting closer like he could sense her.

She messed with the device in her hand. She knew a few things about celestials. One of them was that they were wavelengths, pure energy. She was building an energy dispersing device, in the hope that it would work as a temporary solution so she could get to the library and find some way to trap him.

"What's up, Doc? Are you scared? You can't hide forever. Come on out so I can kill you." She clicked the last piece into place as he opened the door. He walked in, pausing to look around. "Nice picture. Somebody's mom, right? This belongs to 'Roose Tea-lair'."

"Hey." The Doctor said, opening the door. She held up the device by his ear, turning it on. She didn't hear anything, but clearly he did. She threw it on the floor as he knelt down, screaming, covering his ears, and she made a break for it.

John rushed through the back alleys to the daycare. He slipped in through the back door. The teacher stared at him, her eyes wide. "No."

"Where's Rosie?" John asked. He looked at the group of children and spotted her, making a grab for her but he felt something like a gun on his back.

"SURRENDER!" The Dalek said. Rosie started to cry. John nodded slowly. He let the dalek take him out, trying to get a last glimpse at his daughter. They led him outside and transported him onto a saucer. He vanished into blue light, his eyes wide and afraid, knowing that he had to live to protect his daughter.

Sherlock raced to the daycare, but he was too late. "He's- he's on the spaceship." The teacher said, stuttering quietly. Sherlock looked up, knowing that John wanted him to get Rosie to safety, then to come back for him. Sherlock carried Rosie back to the flat, using the alleys for as long as possible. He ducked inside, terrified and unsure of what to do for the first time.

The water was now up to Dean's ears. He breathed in and out slowly, trying to preserve the limited air. Sam was awake, and Dean was still trying to fill him in while saving air. "So… we're gonna die, unless we can get out, then we only have thirty minutes to save our family?"

"I know, it's really overplanned." Dean said. "And if we don't get out, they die anyways."

"Have you tried the trapdoor?"

"It's too hard to open. I told you that already."

"How about blocking wherever the water is coming from?"

"I don't know where that is."

"And Moriarty hasn't talked in two hours?"

"You'd think he'd be getting bored." Dean said.

"You're right, I am bored." Moriarty said through the radio. Sam and Dean looked at it. "You all are boring. Sherlock could've figured it out by now. That's why… 30 minutes starts now."

"WHAT?" Sam yelled.

"Yup. The countdown clock has started, so I'd be figuring out how to get out before it's too late." Moriarty said. "This is one of the easiest puzzles I've ever done."

"Not easy for us." Dean coughed. He was freezing cold, but he had to keep taking off clothing because he was drowning. All he had was a t-shirt and jeans in 59F water. Dean's fingers had gone numb, and his breathing ragged. Sam was better off, but also cold and tired. Neither of them could think.

"Fine then, I'll give you a riddle- and 5 year olds could solve this. 'I hold fate, love, hate, knowledge, and joy, but I do not hold life. I am under a voice but over a body. What I am'?"

Sam frowned, shaking his head. The water was getting higher by the second, and the ceiling was getting closer. The water was about to touch the radio, and their only way to hear Moriarty was going to go out. Sam looked at Dean, but realized that was was gone. Sam dove under, grabbing Dean's limp arms, and trying to pull him upward. Dean kept sinking, like he was a bag of rocks. Sam had to let go to get air.

"The radio and camera are going bye-bye and so are your friends. You only had twenty minutes left to save them anyways." Moriarty said. "One Winchester down, the other one soon enough, right?"

"Wait, say the riddle again!" Sam said.

"'I hold fate, love, hate, knowledge, and joy, but I do not hold life. I am under a voice but over a body. What I am'?"

"A bookshelf! The exit is behind the bookshelf!" Sam gasped. He took a last breath of air and dove under. He dug his fingers under the wooden shelf, pushing it over. It floated up, the radio falling into the water and crackling. Sam twisted the wheel on the door, his hands getting cut from the sharp edges, the water turning pink around them. Finally, with a huge crank, the door swung open, water pouring into the next room, dragging Sam with it. He nearly blacked out, but he managed to stay awake.

"Good job, Winchester. 15 minutes to find the car keys and where your family is." Moriarty said over an intercom as Sam pounded his hands on Dean's chest, trying to get him to throw up the water. "15 minutes and counting."
