It was about midnight when Molly was awoken by a yelp and a thud, followed by hushed voices.

She leapt out of her bed, grabbing the iron rod she kept next to it and sprinted out of the bedroom. She dashed into her living room to find the sofa empty. Molly began running towards her guest bedroom, her heart thudding in her chest as she began thinking of the creatures that may have broken into her flat, that could be killing her brothers that very moment—

She skidded to a stop in front of the guest bedroom, staring through the open door.

The scene before her might have seemed more ridiculous to her if not for the fact that it was the middle of the night and she was standing in her nightgown holding an iron rod and suspecting some evil being of murdering her brothers in their sleep.

Dean, who had apparently fallen out of the bed, was picking up the sheets from the floor, Sam standing on the other side of the bed and another man who she didn't recognize standing at the end of the bed.

"Cas, what have I told you about showing up in the middle of the night?" Dean was saying, sounding annoyed.

"Dean, this is important—"

"What the— who the hell are you?" Molly shrieked, brandishing her iron rod as if to beat the man away.

Both Sam and Dean's eyes snapped to her, looking like guilty little boys caught in the act of doing something wrong.

"Elizabeth— I mean, Molly— this is Castiel," Sam said, looking slightly sheepish.

"I don't care about his name," Molly said through gritted teeth, trying to keep from losing temper. Her panic was beginning to fade as she observed how comfortable Sam and Dean seemed. It appeared that they somehow knew the man. She closed her eyes, making an effort not to scream at them. "I just want to know why there's a strange man standing in my flat." Molly noticed her American accent creeping into her voice.

"He's an angel," Dean explained simply.

Molly sighed. "Dean, I find your tenderness for your boyfriend truly heart-warming, but at this moment I don't really care—"

"Wha—? No! I meant he's literally an angel."

"An angel?" Molly repeated, taken aback.

"Yep."

"Like, as in, from Heaven?"

"Yep."

"Wow. Um, hi, I'm—"

"Yes, I know who you are," Castiel stated, "You're Elizabeth Winchester, otherwise known as Molly Hooper."

"You don't need to do all the introductions. Come to think of it, also skip the getting-to-know-you phase, 'cause we might have a problem on our hands," Dean told her.

"As I was saying," Castiel began, "There are demons here in London. They've been possessing vessels."

"Demons? Here?" Asked Molly. Then she looked at Sam and Dean, her eyes widening. "Do you think it could be… the demon? You know, the one who killed Mum?"

"He's dead," Dean dismissed.

"You killed it?" Molly asked incredulously. But Dean was already back to talking with Castiel.

"We need to get rid of them before it gets out of hand," Castiel was saying.

"So, we just find possessed people and exorcise them?" Sam asked.

"Yes."

"One question," Dean cut in.

"Yes?"

"Can this wait 'til morning?"

Castiel stared at Dean.

"Elizabeth has nice mattresses!" Dean said defensively.

"The situation should not turn critical in the time it takes you to rest," Castiel told him, "But be prepared to fight when you awake. I'll be here."

Molly blinked and Castiel disappeared.

"What… what was that?" She demanded.

"Go to bed, Liz," Dean grumbled, lying back down in the bed.

"Dean, we're not kids. You can't tell me what to do anymore."

"Sam'll explain," Dean said.

"What? Why do I have to?" Sam demanded. "I'm tired too!"

"Come on, Sam," Molly said, glaring at Dean, "I'll make you some tea."

Molly led Sam to the kitchen. She made a kettle of tea and sat down at the table, motioning for Sam to do the same. They sat in the darkness while Molly stirred sugar into the teacups.

"So… Castiel?" Molly raised an eyebrow.

"What about him?" Asked Sam.

"He's an angel?"

"Yeah."

"How did you… meet?"

Sam hesitated. "It's complicated."

Molly studied Sam closely for a moment. The last time she had seen her younger brother he had been a skinny fourteen-year-old worrying about school and girls and things a normal fourteen-year-old should be worrying about, but also balancing being a hunter on top of it all. There was a different edge to him now. He seemed… tougher. He had a more muscular form than she remembered, and there was something in both his and Dean's eyes that made her think they had been through more than they were letting on.

"Did you ever make it to college?" She asked abruptly, suddenly recalling a memory of Sam telling her he wanted to be a lawyer.

"Yeah, for a while," Sam replied, "But… I left."

"Why? You were always a straight-A's kid."

"It wasn't because of my grades. I was actually pretty good," He said, smiling faintly. "But… Dean, he came and got me."

Molly scowled in the direction of her guest bedroom, where Dean was sleeping. "He shouldn't have done that! If you were happy, he shouldn't have forced you to go back to hunting!"

"He didn't force me," Sam said quickly, "I went with him on my own."

"But why? When we were kids you never shut up about going to school and quitting hunting."

"Something happened," Sam told her. He paused, staring at his cup of untouched tea. "My girlfriend died. It was the same demon that killed Mom."

"Oh, Sam…"

"Yeah. It was a while ago."

There was a silence and Molly took a sip of tea.

"So, does Castiel the angel just come 'round to warn you about demons?"

"Nah, he's a friend."

"You have an angel for a friend?"

"I told you, it's complicated."

Molly decided not to push her brother into talking if he didn't want to. They sat in silence for a while, but it wasn't cold or awkward. It was just like when they were children, and Dean would give them dinner and then leave them alone, and they'd just sit together in a companionable quiet.

"I'm really glad to see you, Sam," Molly said suddenly, voicing her thoughts.

"I'm glad to see you too," Sam replied, smiling. "And, for the record, I'm not mad at you. I know Dean's angry, but he'll get over it."

"He's just upset that I ran away. Little daddy's boy," she muttered.

Molly picked up both her and Sam's mugs and spilled Sam's un-drunk tea out (she knew he wouldn't drink it), placing the dishes in the sink to be washed in the morning.

"I'm headed for bed," she told Sam. "You can stay up if you want."

She left the kitchen and walked to her bedroom, instinctively poking her head into the guest bedroom on her way to check on Dean. She shook her head at herself. Dean was more than capable of taking care of himself. It was just her instinct to act like a mother towards them (especially Sam), even though Dean was the oldest. She had grown up being the only female in the family, and she had automatically stepped up as their mum.

Molly crawled into bed and stared at the ceiling, thinking about her conversation with Sam. She wondered what he and Dean had been up to all this time. She would have to ask Dean about that. She hoped they hadn't gotten into too much trouble.

Molly's mind turned to Castiel's warning of demons, a shiver running down her spine. She hadn't dealt with any type of monster in years. The thought of demons showing up in London was frightening, to say the least. She had built up a life for herself here; she had people and things she cared about, and she didn't want to imagine them being harmed.

With these thoughts circling in her mind she eventually drifted off into a restless sleep, her dreams troubled and anxious.

A/N: I'm sorry for the delay, I've been hit with a terrible case of writer's block. This chapter's mostly random filler, but I promise exciting stuff is coming. A huge thank-you to anyone who reviewed, I think I replied to everyone, but I'm very sorry if I missed you. I've been addressed with a few questions from readers, and I just wanted to clear some things up: Molly/Elizabeth is three years older than Sam and one year younger than Dean. The story takes place between Baskerville and Reichenbach for Sherlock, and mid-series eight for Supernatural. Also, this is not going to be a romance between any characters (although I can't ever resist a little Destiel hint here and there). One more thing before I end this astoundingly long authors note: Is anyone out there a beta reader? Even though I always read through each chapter multiple times before I post, an outside view can be very helpful. If you're willing to beta this story, let me know! Thank you so much for reading, and please review!
