And here we go, right through the door, look out guys here comes Chapter 4!

Man... that was bad. I apologize for that... good grief that was awful. XD Hope you guys enjoy this chapter anyway! We're gonna get a better look at Louise and some OTF scenes in Minnesota too :D

Dr. Lincoln's stature made her seem like a woman who took absolutely nothing from anyone - however, after talking with her for a bit, the three noticed that she was a lot sweeter than she let on.

"Your father constantly talked about how much he missed you... and wanted to get back to you," Louise said. "He said you were the light of his life."

"I... I can't thank you enough, Dr. Lincoln," Caitlin said. "You've helped us so much already."

"No worries about it," Louise smiled. "The tracking nanites that he took with his water the day he went underground are a very old model, so it might take me a while, but I think I might be able to help you all pinpoint a signal. It will take me a bit... but I think I can do it."

"This means so much to us, and especially Cait, Dr. Lincoln; we can't thank you enough," Barry said.

"I'm just doing what I can to help," Louise said. "After all, Thomas was one of my best friends. I'll be damned if I won't do anything for his daughter, too."

Caitlin hadn't felt this happy in what felt like... nearly forever. But now, here she was, and she was inwardly as bubbly as could be.

It felt great to be so happy again...

Barry offered a supportive smile to his best friend, and she smiled back. Then, she squeezed his hand - she didn't know why. But she felt so comforted when Barry didn't pull away from her grip, only tightening his own. Cisco was beaming too, and she gave him a smile and a twinkle in her eye.

"Well, I have work to do, sadly," Louise said. "But I will get in touch with you all if I find anything on Thomas, or if something shows up."

"Thank you so much, Louise," smiled Caitlin. "I... I owe it all to you."

"Don't sweat it," smiled Louise. "Its what I want to do."

With that, the three exited Louise's office, and then the University campus. While Cisco ran off to go get doughnuts and food on his insistence, Barry and Caitlin made their way back to the hotel room.

The moment they got back to the hotel, Caitlin plopped down onto her bed, and buried her head into her hands.

"Cait?" Barry asked, walking closer to her - he could hear she was crying by now. So he did what his instincts told him to - he sat down next to her, and wrapped his arm around her waist, holding her close so she could find comfort.

"I-I'm s-sorry..." she whispered a few moments later.

"Oh, Cait, you never have to be sorry if you need to cry," Barry said.

"I-I'm just a bit... a bit overwhelmed," Caitlin admitted. "I've f-felt so many emotions over these past few days... I guess it all just kinda... poured out, y'know?"

"I know, yes," Barry nodded. "That's happened to me before. You have no reason to be ashamed, Cait - its normal."

Caitlin looked adoringly into his eyes, before resting her head on his shoulder. "Barry... you're just... the best. The best guy a girl could ask for..."

Barry rubbed Caitlin's back lightly, and smiled at her. "And you're the best girl I could ask for..."

He then did something unexpected - he leaned over, and kissed her cheek.

Caitlin's cheeks turned bright red at this sudden contact... but that wasn't a bad thing. No, quite the opposite.

She then smiled, and cracked a joke. "What took you so long?"

Barry chuckled, and squeezed her hand again. "When we find your dad... and we actually get to sit down with him... I've got so much amazing stuff to tell him about you, for sure."

"And he will love you instantly, trust me," Caitlin beamed.

They then moved in to each other, leaning towards one another's faces... When suddenly, Cisco knocked on the door. "I come bearing gifts!" the engineer yelled.

Caitlin and Barry broke apart, shared a small giggle, and walked to the door to grab their friend and his treasure - Caitlin instantly devoured a pink doughnut when the food found its way to the table, which earned her a funny look from Barry and Cisco, who were planning on doing the same thing.

Barry then noticed how cute Caitlin looked with pink frosting staining her lips...

Anyway, Cisco had also brought a ton of pizza, which everyone happily dug into.

All seemed to be going right for them...

Louise, however, was a bit frustrated - her work wasn't going as well as she was hoping it would.

She was just about to punch a hole in the wall... this was really frustrating.

So, therefore, she decided to look at something on her phone. However, instead of looking at cats on Reddit or pulling up Twitter, she did something else...

She pulled up security footage.

Of Thomas walking around in his lab in the North Pole, right as he encountered Team Flash.

"I knew they were different," Louise muttered.

As she further studied the footage, she noticed how Caitlin seemed a little more resistant to the cold than everyone else.

"Hmm... resistant to cold, now, are we?" Louise said coyly.

She then stood up...

And her hair turned crystal blue, and frost started emitting from her fingers.

"Let's have some fun with that, shall we?"

oh no Louise is a villain :O :O :O But if you thought that was the plot twist... you've got another thing coming my friend. ;)

Anyway, I hope you guys enjoyed! BARRY KISSED CAITLIN'S CHEEK AAAAAAAAAHHHHHH AND THEY'LL KISS FOR REALSKIS SOON AND I NEED SLEEP SO SEE YOU GUYS NEXT CHAPTER I LOVE YOU ALL :D :D :D
