Author's Note: Realized that I hadn't done any of these... so I had to get it done tonight! I've been craving some crossover writing, because I've been watching scenes from a crossover show, and it's just making me so happy. So here we go.

New Years Eve. Caitlin leaned back against the couch cushions in Barry's house, and watched all of his guests buzzing around, drinking champagne and talking. It was an hour until midnight, but Caitlin wasn't sure if she was going to make it that long. Already the alcoholic drink was making her feel warm and sleepy.

Felicity plopped down on the couch next to Caitlin. "Hey, Caitlin." She gave her friend a little smile. "You ok?"

"Yeah." Caitlin pushed herself a little straighter. "This year's just gone by really fast, and there are a few things I with I'd done."

"I know what you mean." Felicity's eyes found one of the best looking men in the room, Oliver Queen. She sighed, then repeated. "I know what you mean."

Caitlin gave her a side glance. "Felicity, I don't know exactly what has been happening with you and Oliver lately, but I know this: He loves you, and you love him right back. What more could you need in your relationship with someone?"

The tech wiz didn't answer, but her eyes seemed like they weren't actually seeing the room she was in anymore. Caitlin took another sip of her drink, and stayed quiet with her.

After awhile, Felicity looked over to Caitlin. "How about you?"

"What about me?"

"You and Barry." Felicity nodded over to the corner, where Barry was goofing off with Cisco.

A flicker of a smile crossed her face, even though Caitlin didn't actually seem conscious of doing it. She followed Felicity's gaze over to Barry, and then her head lolled back into the couch. Felicity was shocked to see tears in her eyes.

"Hey.. what's going on?"

"I don't know, Felicity." Caitlin whispered. "I don't even know when I fell for him. I started thinking about him a lot, and I don't know, I just realized it one day. I realized that I was in love with him. And now I don't know what to do with that."

"You tell him." Felicity stated simply, rubbing the young doctor's shoulder. "When it all comes down to it, you're either going to have your heart broken or you'll get your dream. If you don't tell him, it's a 100% chance of heart break." She paused, and her eyes fell on Oliver. "I'm such a hypocrite, aren't I?"

Caitlin laughed quietly. "No. You did. You told him how you felt."

"And then I turned around and crushed it all to dust after one mistake on his part." Felicity argued, tears filling her own eyes. "How can I expect him to take me back after that?"

"What is wrong with us?" Caitlin asked desperately. "Here we are, two pretty, smart, talented woman, and we're both completely stuck on two amazing guys. We're just getting in our own way for having everything we want."

"Well..." Felicity smirked. "It is New Years. You know, clean slate and all that."

Caitlin smiled. "Well..." The smile turned to a smirk. "There is still some mistletoe hanging."

Felicity laughed. "Let's make a deal. I'm going to call you in 2 months. If you are not dating Barry by that time, or at least have told him how you feel, then, well, I have no idea what I'm going to do. And if I haven't at least talked with Oliver, then you have perfect right to never speak to me again."

"Not going to happen." Caitlin assured her. "But it sounds like a deal."

They clinked glasses, and both fell quiet, watching the two men they loved.

Author's Note: Well, that was fun. Sorry if there were typos; I was watching the New Years Eve show thingy as I was writing this, so only half my brain was on it :P
