Jen was reading her book when Yuki came in. "Hey, Yuki. What's up?"

"Are you sure it's okay for me to stay here?" Yuki asked.

"Of course it is." Jen said. "Besides, you're like one of us." Mini Chill flew over to Yuki.

"I came in to check on him." Yuki told her.

"He's really happy that you're here. And so am I." Jen told her. "Can I ask you something?"

"Go ahead."

"Did you come here because you developed a human form?"

"Sort of." Yuki explained. "I had to come here. A human wouldn't last long on my homeworld."

"At least you have us around." Jen said. "Just don't use your powers in front of other humans. Some of them aren't as accepting as you'd think."

"I see. Thanks for the advice." Yuki said. Mini Chill headed back to the nightstand. "He's told me about how you saved him that night you met."

"Yeah, things got a little crazy with Ship, but we managed to work it out." Jen said.

"Ship! Ship!"

"Down, boy!" Jen said, laughing. Yuki smiled. "We should get some rest. I can show you around tomorrow."

"Okay." Yuki left the room and almost ran into Julie. "Oh, sorry."

"It's okay." Julie said. "I was coming in to see how Jen was doing. Anyway, how are you adjusting to your new life here?"

"It's a little complicated, but I'm getting the hang of it." Yuki told her. "Jen and her friends are very accepting."

"So are their parents." Julie said. "We've been involved in the Plumbers for a while now. If you ever need to talk to any of us, we'll be here for you."

"Thanks." Yuki said.

The next day, the group, along with Yuki, decided to take a shortcut through the park into town. "Hey, Jen!" Matt headed over to the group. "Why didn't you call back last night?"

"I'm sorry, I was busy trying to help a friend get settled in." Jen explained, gesturing to Yuki.

"You must be new here." Matt figured. "I'm Matt."

"Yuki." He shook her hand, then pulled away.

"You're hand's practically freezing."

"She just came from Anarctica." Jen covered. "So she hasn't fully recovered from the ice tempurtures yet."

"Jen. I've known you a long time, I know you're making that up." Matt said.

"Long story, I'll explain later." Jen promised. "Bye!" The four of them headed off.

"Why did you try and cover her identity like that?" Aaron asked as they headed into town.

"He and our other friends don't know about her yet. I don't want a repeat of the Sarah incident." Jen told them.

"But, they're Plumbers' kids, too." Allison pointed out.

"I'll tell them tonight." Jen said.

"If we're not in the park, how come we are still running?" Yuki asked.

"You know, the new girl's got a point." Aaron said. The four of them stopped in front of a jewelry store.

"Okay, I'll admit that running from him was a little out of character for me." Jen said. "How about we show Yuki around?"

"I'm going to check out the bike shop. I'll catch up with you girls later." Aaron said.

Jen and Allison showed Yuki around a few stores and the mall. They stopped by the fountain to relax. "That was really fun." Allison said.

"That skirt looked totally cute on you." Jen told her. "You should totally wear it when you and Frank go out on your next date."

"I don't know." Allison said. "Ever since we found out about each other, there's this part of me that doesn't trust him. I really like him, but at the same time, I feel like I just want to be friends with him."

"Ali, you can't be serious." Jen said. "You're both into each other. I saw the way he looked at you when you took down that bounty hunter. He was worried for your safety."

"I think that you should trust your instinct." Yuki told her. "Where I'm from, we believe in following our intuition and trusting ourselves."

"Thanks, Yuki." Allison said. "That's really good advice."

"I was raised by someone who taught me a lot about our kind and yours." Yuki explained.

"I should go. Aaron's probably looking for us and I don't want to get into trouble with Dad again." Allison said. "See you around."

While Jen and Yuki were walking back, they were unaware they were being followed. "I never expected that people like you had such amazing places to hang out." Yuki said.

"Well, we don't really get out much, but we know every part of this town." Jen said. "I could take you to our secret lake tomorrow. It's one of our favorite places to relax."

"Sounds like a plan."

"Oh, I almost forgot." Jen said. "I got this for you. It's to remind you that you're part of our family." She handed her a necklace with a snowflake charm on it.

"It's beautiful. I really had a great time today." Yuki told her. She stopped for a second.

"Are you okay?" Jen asked.

"I'm getting a bad feeling. It's like there's something close by." Yuki said. "Most of my type usually get this feeling when they're feeling a threat is near."

"Kind of like Gwen and Ali." Jen realized. "Let's check this out." They headed into an alley to find a creature. It looked human enough, apart from a few features. Yuki recognized it.

"I've seen something like that before." It was over something. Jen looked closer. The twins were there. Allison had her shield up around herself and Aaron.

"Let's go!" Jen said. "My friends are in there!" Yuki transformed and started to attack with multiple ice blasts.

"A single Necrofriggian can never defeat me." The creature said. Aaron jumped over the shield and attacked him. "Enough games. I will get the Omnitrix."

"Another one of these losers?" Allison said. "Please!"

Jen heard something chirp behind her. She turned to find their little blue friend flying behind her. "Hey, little guy. Your mom and I could use a hand." He chittered. Jen transformed into Big Chill and flew over to Yuki. "I say it's time we put this guy on ice."

"As if she'd ever help you. Necrofriggians despise humans." The creature said.

"It doesn't matter what I am." Yuki said. "I'll never let anyone hurt my step-sister!" All three Necrofriggians fired their ice blasts at him, freezing him solid.

"Nice work." Aaron said. The girls changed back to their human forms.

"Thanks, Yuki." Jen said. "Couldn't have done it without you."

"What can I say? We're family." Yuki said. "I would never let anyone hurt you."

"Same goes for all of us." Jen said.

"In a way, it's like we're all family." Allison pointed out. "Considering we're all part alien."

"Anyway, I parked out back if you guys need a lift." Aaron said.

"Tell me you didn't take the car again." Allison said.

"I didn't." Aaron said, leading them to Ship. "I ran into him on my way to the shop." He shifted into his hovercraft form.

"Your little pet is amazing." Yuki said, surprised.

"I know." Jen told her. "Come on, everything will be okay." They all boarded the ship and took off for home.
