(A/N)-Hey guys! I'm sure you're going to hate me for writing two alternate-dimension chapters right next to each other, but I just can't think of a way Lydia could possibly be relevant in 6.16. I also didn't like that episode very much, and it's my story, so I'm skipping it and going directly into "My Heart Will Go On". Thank you to all of you who reviewed, because it's always much appreciated and I'm so grateful for it. The last chapter was really long, but this one is really short, so maybe that balances it out a bit. I don't know how many of you have read the spoiler for 7.13, but apparently they're bringing in a "lust interest" for Dean named Lydia. That's definitely but awkward, but oh well. (And for the record, my Lydia looks nothing like Sara Canning, who's set to play the cannon Lydia. I think Lydia Carmichael looks like Lauren Leech, an actress, but that's just me.) I'm sure you're sick of these long author's notes, so I'm to shut up now, except to ask how many of you participated in GISHWHES and that I own none of the cannon Supernatural characters. That's the CW, lucky bastards…EDIT: Did anybody watch "Death's Door"! I cried so much, guys, I need therapy.

Castiel had known that when Balthazar unsank the Titanic, the world would change. The world would not only gain tens of thousands of souls, but other changes as well. Some would be drastic-the cure for cancer was discovered, World War III had broken out in the 60's, 9/11 had never happened-and some would not be so drastic. Just small, little changes. Ellen and Jo Harvelle were alive, Ellen was married to Bobby, and Celine Dion was some unknown night-club singer.

But Cas had never imagined that she would be married to another man.

He watched Lydia as she walked down a street in Chester, Pennsylvania, hand in hand with her husband, Alex; the same Alex who, in the original world, had gone on only one disastrous date with Lydia. But apparently, things had worked out quite differently in this world.

"Lydia Clarke." Cas turned to see Atropos, one of the Fates, smiling bitterly at him. "Born July 1st, 1986. Born to Catherine and David Carmichael, who divorced when Lydia was a young girl." Cas looked at her, pained, but Atropos continued talking. "Her mother remarried a man named Arthur Gillian when Lydia was nine, and they moved to Chester, Pennsylvania." She got a sick satisfaction watching Castiel's face. "Lydia and Catherine visited a family friend, Alyssa, in Iowa City when Lydia was nineteen, and she met Alex Clarke, an engineering student."

"Stop." Cas thundered.

Atropos didn't stop, not even for a second. "They married when they were both twenty-three and moved back to Chester. He's an engineer and she's a first-grade teacher." Atropos finally unleashed the biggest blow to the angel. "She doesn't know it yet, but she's pregnant with their first child."

Cas shook his head, trying not to look distraught, and looked back at Lydia. She and Alex were frozen, just as Sam and Dean were, by Atropos. The agent of fate finally let her anger seep through and yelled, "I hope you're satisfied with yourself, Castiel! Do you realize what you've done!"

"Okay, let's talk about this." Cas tried to clear all thoughts of Lydia from his mind. "There's no reason to get emotional."

"Not get emotional!" Atropos screeched. "I had a job, Castiel, and I was very good at what it! Then you and those two clowns…" She pointed at Sam and Dean. "You threw out the book and screwed everything up! Nobody in Heaven would even talk to me anymore! I'm useless!"

"There are more pressing matters at hand." When Atropos started to protest, Cas silenced her. "Your services are no longer required."

Atropos was growing angrier and angrier. "You cannot just unsink an entire ship, Castiel! It doesn't work like that! And don't give me some crap about Balthazar hating some stupid movie, because I know for a fact those orders came from you."

"No, Atropos," insisted Cas. "You're just confused. I wouldn't do such a thing because I have no reason to do such a thing."

"Come on, you and I know this is all about the souls." Atropos stepped threateningly closer to the angel. "That angel created 50,000 new souls for your war machine! You're getting desperate." Atropos shook her head disapprovingly. "You can't just mint money, Castiel. I won't let you."

"You don't have a choice." Cas challenged her.

"Oh yeah?" Atropos boldly got right up in the angel's face. "What about your two little pets over there? If you don't sink the Titanic, I will kill them." Sarcastically, she added, "You're not fighting a war or anything, right? So you can watch them every second of everyday?" Atropos even went a step further. "And your little girlfriend?"

Cas' nostrils flared as he barked, "Don't you threaten her!" His breathing was erratic and heavy. "I will personally end you if you so much as touch a hair on her head."

Atropos shrugged. "Oh, I won't kill her. No, I've got a better idea. I'll kill her mother, her stepfather, her husband…her child." Cas looked at her furiously as she eyed Lydia and her husband. "After what you did to me, I can promise you that I'm not above killing a child."

Cas was seething, but he only avoided Fate's glare and said, "Balthazar, don't."

Atropos looked behind her sharply and saw Balthazar, his arms raised, ready to kill her. Innocently as possible, Balthazar said, "Uh…awkward."

Atropos turned back to Cas. "Sink the boat before I flick your precious boys off a cliff." Dangerously, she added, "And don't even get me started on the girl."

"Well then," Balthazar clapped his hands together to relieve some of the awkwardness. "Let's go sink the Titanic."

Lydia Carmichael was at Bobby's house, cleaning her gun as Bobby slept on. She kept glancing up at him every few minutes, hearing him muttering in his sleep. He had just lost Rufus, one of his old friends, and was drinking more than he usually did. Lydia felt terrible about the whole thing, especially how broken-up Bobby was about it. He tried to hide it, but Lydia could clearly see how upset he was.

Then, Lydia felt a cool breeze and looked up to see Castiel standing in the middle of the room. "Cas…" she whispered. Before she knew it, he had rushed over and threw his arms around her, pressing her closely against him. He buried his face into her hair and breathed in deeply, contently. Lydia just stood there, not quite hugging him back, confused. He wasn't usually so outwardly affectionate, nor did he ever cling to her as desperately as he was right now. "Cas, you okay?"

The angel nodded, then pulled away and looked at her, smiling-something Lydia hadn't seen him do in a while. He started playing with her hair and looked her directly in the eyes, his blue ones staring into her hazel ones. "I missed you." He murmured quietly.

"Um…" Lydia was really confused. "I missed you too…"

"Back in Iowa," Cas began. "Do you ever wish you had stayed with Alex instead of me?"

"What?" Lydia became even more confused, if that was even possible. "No, of course not. Why are you asking about...?" Cas cut her off by kissing her on the lips passionately. All of Lydia's thoughts immediately raced away from her, and there they stayed for a few second, their lips moving in sync and that old, familiar feeling of red-hot passion coming back to them. Eventually, Lydia broke away, her breath coming out in short, nervous bursts. "Sorry, I just…"

"No," Cas stroked Lydia's cheek lately. "I just…forgot. I haven't seen you in so long, I should've known…"

Lydia, how was looking down at the ground before, suddenly raised her head and kissed Castiel again, even harder this time, her hands cupping his face. She stopped, took a deep breath in, and quivered, "I can do this, Cas. You just have to…go slow, okay?"

Cas nodded, then finally noticed Bobby sleeping on the couch. "We should probably go…somewhere else…"

"Yeah," Lydia giggled as she nodded. "It'd be kind of weird with Bobby, you know, right there…"

They trailed off into an awkward silence, then grabbed each other and started kissing again. It was slightly strange and foreign to them, because they hadn't done this in such a long time. But after Cas' hands started moving from her back to her butt and Lydia's were moving to take his trench coat, any trace of awkwardness or hesitation was gone. Cas knew he shouldn't make any sudden movements, but in the heat of the moment, he grabbed Lydia's waist and lifted her up so his left arm was supporting her back and his right arm was underneath her knees. He carried her bridal-style to her bedroom, and they continued to French kiss as he did so. Cas stood next to the bed and quietly asked, "Are you sure you can do this?"

In response, Lydia just kissed him harder, and Cas dropped her on the bed and got right on top of her. Gently, they removed each other's clothes until both hunter and angel were completely naked. Finally, it happened. Cas made pure, unadulterated love to Lydia for the first time in a very, very long time. It was everything they had hoped it would be, and it felt amazing.

After it was over, they lay in bed next to each other, their faces flushed red and their breathing irregular. Cas was smiling-actually smiling-and looked over at Lydia to tell her something. He stopped, however, when he saw Lydia staring at him, tears glistening in her eyes.

"Lydia?" Cas propped himself up on one of his elbows and reached out for her, concerned. "Are you okay?"

Lydia nodded, sniffling and wiping her cheeks dry of any moisture. "I'm fine."

Cas was still confused. "Why are you crying?"

Lydia let out a laugh as she started to regain her composure. "I have no idea, actually. I just got…really overwhelmed with everything, y'know?"

"Yes." Cas lied. He actually didn't know, but he would at least try. "Did you not enjoy…what we did?"

"No!" Lydia's eyes widened. "No, don't take it like that. It was great. I just had flashbacks to what happened with Sam. But I'm fine. Really, I am."

"Oh," nodded Cas. Then, he let out a frustrated groan as one of his sisters sent him a message in his head. "The angels require my presence again."

Lydia chuckled. "When don't they?" She wasn't crying anymore, but her eyes were red and puffy, and there was something in them; something like fear. Lydia traced Castiel's lips with her finger. "You should probably get going, then."

Cas looked unwilling, but he nodded again. "Yes." He got up to get dressed, wishing more than anything he could stay for a little bit longer, but there was just no possible way he could. "I'll be back soon."

"I know." Lydia knew the drill. It seemed they were doing this all the time now.

Cas, once he was finally dressed, nodded curtly. He was just about ready to go before Lydia called out, "Wait!" Cas looked at her, surprised, and Lydia bit her lip. "Why did you ask me about Alex earlier?"

"I don't know," shrugged Cas. "I was merely curious."

"You sure?"

"Yes."

"Oh," Lydia got out of bed, slipped on an oversized t-shirt, and went over to give Cas one last kiss. "Stay safe, angel boy."

"I will." And just like that, Cas was gone once again.
