"What is all this crap?" Cora says gesturing to all of the new things in Derek's loft.

Derek sighs, sitting on his couch running his hands over the unwrapped gift he's been holding for over an hour. "Stiles feels guilty for sleeping with Lydia. He's basically buying my forgiveness when he doesn't need to."

She scoffs, "Bull, he cheated on you. He's lucky I don't rip his throat out with my teeth."

He puts the present down. "I gave him permission, Cora. I wanted him to have that experience, but then something else happened between us."

"What?" She asks strumming her fingers over the unopened high-def television sitting beside her.

Derek's eyes widen when he sees her claws come out. "Don't open that!" She stops with the tape barely touching her nail. "I'm taking everything back. There's no way Stiles can afford all of this stuff."

"Okay, now tell me what happened." She says with a low growl.

He sighs, "Stiles and I ... when he was with Lydia, you and Erica..."

"Were ripping you to shreds?" She finishes for him.

Derek nods, "But I could feel everything he felt, and he said he thought he was sleeping with me and not her."

Her eyes widen. "That means...but how? I've never heard of it happening between two males before!"

"I know!" He says dragging a hand over his face. "It's weird. I know it means we're soul mates and all, but I haven't told him what else it means."

She punches him in the arm. "Are you stupid?! You know how bad this could be!?"

"Do not lecture me, Cora! I know too damn well what this means." He sighs and returns to the gift and tears off the shiny blue wrapping paper.

His eyes widen when he sees not that it's a book, but what book it actually is. The Last of the Mohicans, is sitting in his hands, it's cover is old and warn, but he knows how old it is, when it was published, and how rare of a find this is. This was something Stiles could never afford. This was a first edition. This was one of the first ever printings, and worth several thousand dollars. He flops back to a seated position on the sofa, mouth gaping.

"What? It's just a book." Cora says looking at the thing like it's worthless.

He meets her snarky gaze and quips back with, "And hell is just a sauna."

She growls and stomps her way upstairs. Derek carefully opens the cover and finds a note tucked inside. He unfolds it while simultaneously putting the book on his coffee table. The note is from Stiles.

Derek,

I did something terrible. I know we agreed that I could do it, but after I did I felt like the biggest betrayer since Judas, and he only betrayed his friend! I love you and I will do whatever it takes to show you how much. Now, I know this is your favorite book, and yes I know how valuable this one is. I didn't steal it, and I didn't buy it. It belonged to my mom. She got it from my Dad, who got it from his dad. Mom told me it was her favorite. She even read it to me a couple times before...Anyways, I asked dad if I could, because I know you and I are forever. This is your favorite book, Derek. I love you more than anything, and you deserve a piece of happiness, even when I'm trying to ruin things. I hope you look at this book and smile, because even though that smile of yours is rare...Derek, it's the most beautiful thing about you.

Yours forever,

Stiles

Derek closes the note, and puts it back in the book. "You need to go somewhere, very special." He says picking up the book. He smiles wide as he looks at it. He places it on a shelf, just above his bed. He taps his finger on a section of bricks and the wall pops open. A hidden safe, now open, Derek takes the book from the shelf and places it inside, next to it a family photo with burned edges, and a small, black velvet box with a note on top that simply says, Someday.

He takes out his phone and calls Stiles.

"Derek! Baby, I'm so sorry! I know I've said it a million times, but I am...sorry that is. I love you and this whole soul mates thing is the best thing ever!" Derek is smiling the whole time Stiles rambles on.

Finally he interrupts, "Stiles...STILES! Stop! I love you. I want you to come over. Please."

Ten seconds pass before Stiles is sliding open the loft's door. "Thank God! I've been in the parking lot all day!"

Derek laughs and walks up to Stiles, "Stop apologizing. I was only upset for day or two because I was jealous and," he sighs not wanting to admit the truth, "I didn't think it would actually happen, and I might have gotten scared you'd leave me for her."

"Never!" Stiles says quickly and without thinking. "Never, ever!"

Derek grabs him and kisses him hard. "Good, because I need to talk to you about this whole soul mates thing."

...

Lydia is sitting on a table in Deaton's clinic feeling utterly humiliated. Allison is stand there, holding her hand.

"It's going to be okay, Lydia. Deaton's going to help figure what this is." Lydia doesn't even hear her best friend.

The sound of a single dog barking has her attention. She stares at the kennel room's door. The dog can't be very big, since it's bark sounds similar to Prada's. She slides off the table and goes to the door. When she opens it, the room and cages are empty. Still she hears the barking. She goes over to the door of one of the bottom cages, a dog's name is written on a piece of paper and taped to the door. Bullet it reads. Lydia takes the nametag and turns to see Deaton standing there.

"His owner just left him last night." Deaton's voice startles Lydia into reality. She nods. "He just disappeared. Had to call his father to come pick the poor thing up this morning. Strangest thing is...his car was here all night."

She looks at him with wide, confused, yet knowing eyes. "He didn't leave. He was taken."

Deaton sighs, "I feared as much." He changes his demeanor back to his usual self, changing the topic. "Now, Allison tells me you're pregnant."

She nods, "About two weeks along." She looks down at her shoes and realizes where she is. "Why Allison brought me to a veterinarian is beyond me."

Deaton smirks, "Well, since the father is a hybrid and we're not entirely certain as to what Peter's bite did to you, I might be the best person for the job."

"Great," She groans.

Deaton leads her back to the table and produces a sonogram machine.

Lydia turns to Allison, looking more annoyed than ever.

"Just give him a chance, Lydia." Allison turns to Deaton, "Is a sonogram even necessary this early?"

He sighs quietly, "Usually it would just show the fetus, but if this baby is what I think it is, based on what Lydia told you...it might be further developed than just a few weeks."

He has Lydia lay back. She raises her shirt before he applies a cool liquid to her stomach and runs the machine over her skin. A rapid heartbeat pulses from the machine.

Lydia's eyes widen, "It's way too early for that!"

"Not with the kind of baby you're having Lydia." Deaton says looking at a baby developed much farther along than a couple of weeks. "It appears this baby, if I were comparing it to a normal one, is about three months along."

Allison speaks for a perplexed and freaked out Lydia. "So what does that mean?"

"It means," Deaton says rubbing his forehead, "that this baby will be born in a few weeks if not days, and it definitely isn't Lydia's baby. It's Derek and Stiles'."

...

"Wait, I'm now a what?" Stiles asks pacing back and forth in Derek's loft.

Derek sighs, "This is why I've been avoiding you. I knew you'd freak out."

Stiles raises his finger, shaking it sporadically in Derek's face. "I am not freaking out!" He withdraws his hand and his voice quiets, "I'm processing. There's a difference."

Derek laughs, "Stiles, you're an alpha now too. It happens when the alpha of a pack finds their soul mate. It's really rare, and I've never heard of it happening between two males before, but..."

"Does this mean I'm like the alpha female?" Stiles looks like he might puke. Then a sudden new fear hits him hard, "Oh God! Can I get pregnant?! Because if so we're using condoms and I am going on the pill tonight!"

Derek can't decide if he should laugh or be annoyed. He just sighs, "No, Stiles, you're not the alpha female and you can't get pregnant."

"You don't know that!" Stiles interjects, his heart beating so hard it feels like it's jumped into his throat. "You said it yourself you've never heard of this happening between two guys before."

Derek's holding him the second he finishes his sentence. Stiles relaxes into the embrace. "I don't wanna get pregnant," He wines. "How will I explain it to my dad?"

Stiles feels Derek's lips kiss the top of his head, his nose nuzzling around in his messy brown hair. "Stiles, shut up."

Stiles sighs and wraps his arms around Derek. "Okay."

...

Allison and Lydia are just about to leave the vet's office when Scott walks in holding hands with Isaac. Allison's eyes meet Scott's and they both freeze. Isaac flinches when Scott drops his hand and he looks at Lydia who looks completely unfazed.

"When," Allison asks pointing a finger back and forth between the two betas.

Scott grabs Isaac's hand again and Isaac smiles, "A few weeks before summer ended."

Allison nods, mouth gaping. "O-okay. Well, Uh, Lydia, we need to go find Stiles and Derek."

"Why are you looking for Stiles and Derek?" Isaac asks, finally speaking.

Lydia sifts her near vacant eyes to the blonde beta. "I'm having their baby."

Both Scott and Isaac have to scoop their jaws off the floor while they watch the girls leave.

...

A/N: Okay this one's a little short, but I kind of like how I ended it. So I hope you guys will like it and continue to review/comment. This one's a little more fluffy than the others but I have a feeling the next few chapters will have more dealings with the Alpha pack, Erica, Cora, and a whole mess of questions revolving around the baby.
