There she was standing outside the very door that she remembered using countless times. Lydia stood beside her, held her hand and opened the door. Both stepped inside and closed the door.

"Lydia, is that you? I was wondering what we should eat for lunch?" Their mom walked down and stopped in her tracks. "Emma?"

"Hi, mom." Emma smiled shifting uncomfortably.

The next thing they knew Mrs. Martin was on the floor. Emma and Lydia ran to her side and found her to have fainted.

"Come on, I'll take her to her room." Emma said as she scooped her mother in her arms and carried her upstairs.

"Well, she handled that better than I thought." Lydia replied.

"Really? I wouldn't have guessed."

"I see you're still the same old Emma." Lydia muttered.

"Werewolf hearing, remember?" Emma exclaimed from upstairs.

When their mother was safely tucked away in her bed, Emma joined Lydia in her room. Lydia was on the phone with someone.

"Yeah, she's back. Mom all but fainted. Yeah she'll be fine. At Derek's loft? Okay, see you then. Bye."

"Who was that? And what about Derek?" Emma immediately asked.

"That was Allison, my best friend. We're all meeting up at Derek's loft to discuss something, I guess."

"I'm coming with."

"Sure, but maybe you should go change."

"What, why? What's wrong with the clothes that I'm wearing?"

"Well, if you're going to your boyfriend's house the least you could do is dress to impress. I mean, you're beautiful but that doesn't mean that you shouldn't dress well."

"What? No, he's not my boyfriend. And he's already had a run in with me. My clothes are fine. Let's just go please!"

A chorus of hellos went around the room as Lydia introduced Emma to the pack. She gave them a wave and a smile.

"Lydia, man your sister is hot!" Aiden exclaimed only to shut up upon seeing Derek standing right behind her and giving him an 'i-will-rip-your-throat-our-with-my-teeth-if-you-don't-shut-up-glare'.

"You, I need to talk to." And with that Derek pulled her away and out the loft only to bump into Peter.

"Well if it isn't Emma. My how you've grown." Peter smiled.

"And you're still the same son-of-a-bitch." Emma punched Peter but before she could cause anymore damage, caught hold of her and carried her away.

"See you soon!" Peter waved cheerfully at the retreating couple and entered the loft. "Who knew that the banshee was related to the werewolf?" He said to no one in particular and retreated into his room.

"Why is he alive? Why haven't you killed him yet?" Emma screamed at Derek as he put her back on the ground.

"You can thank your sister for that. He was very much dead before she brought him back." He recoiled back.

Emma combed through her hair with her fingers in frustration. "What the hell is going on here?"

"You tell me. When I told you to leave, what the hell are you still doing here?"

"I'm not leaving, Derek. I already told you that much yesterday! Don't make me repeat it!"

He pulled her body flush to his, "Why are you back?"

"You already know." She whispered and searched his eyes. "I'm here and I'm not going to leave again. I know you sent Cora away because it wasn't safe. But I'm not going away. Not again. You need me here."

"You're just as stubborn as you were back then." He smiled sadly.

"I know." She whispered and he released his grip on her but neither moved from their position. And then she was hugging him, afraid to let go. Derek raised his hands and lightly placed them around her body.

"You're back."

"Yup and you can't get rid of me that easy."

The gang watched them from the window above.

"So, what do we make of this Emma character?" Stiles asked. "I mean, can we trust her?"

"Well, if Derek trusts her then we can trust his judgment, right?" Scott replied.

"Umm, hello! Am I the only one who remembers Derek's pathetic choice in women?"

"Umm, hello! That is my sister down there. And she isn't a pathetic choice." Lydia stated.

"And she's hot." Isaac brought forward only to be swatted by Allison.

"If you guys value your lives you'd stop with the whole 'hot' thing. My nephew isn't very good at sharing." Peter said smugly as he sat down on the couch.

"Besides, Cora before she left told me all about her. They've been living together in South America."
