Near the end of shift, Sara sat alone in the break room with her cup of coffee, as she tried to read the news paper. Her eyes moved across the page, then up to the door periodically, searching for Catherine. She'd managed to avoid her all night, though she was certain Catherine had caught her once as Sara had seen her coming, then ducked into an empty lab.

"I'm gonna grab some coffee," Sara heard Warrick's voice, just outside the room. "Care to join?"

"Don't mind if I do," she heard Catherine reply playfully.

Oh shit! Sara's brain screamed. Shit! She's coming in here… she's coming in here, and I'm trapped like a rat… shit!

The mere thought of seeing her was making Sara's hands visibly shake with nerves and what she thought might be a hint of… excitement? She fought the urge to push the thought away. Great, now I'm fighting with my thoughts about fighting my other thoughts. Allowing the idea back to the surface, she decided a part of her was indeed looking forward to seeing Catherine. The new thought sent a rush of butterflies through her stomach, which only made her more nervous. Maybe she should have pushed the thought away after all.

Then, there was Catherine in the doorway, still talking to Warrick. Though she knew it was scientifically impossible, Sara was certain she felt her stomach physically flip over at the sudden sight. As their eyes met, Sara tried to say something, anything, to make Catherine believe she didn't feel awkward. After a moment of holding her gaze, and being unable to get control of her shaking hands and racing pulse, Sara gave up, bashfully turning her eyes back to the paper.

"Hey, Warrick," Catherine said after a moment, "I forgot…something… in my office. I'll catch up with you in a bit, alright?"

Yep. She definitely saw you avoiding her before. Smooth move, dumbass.

"Sure, Cath," Warrick said, stepping into the break room as Catherine turned and walked away. Sara's cheeks were on fire. She avoided making eye contact with Warrick, hoping he wouldn't notice. He did.

"You two going at it?" he asked.

"Going at what?" Sara asking, sounding almost panicked. "We're not "going at" anything!"

Warrick shot her a confused look, then chuckled.

"Fighting, Sara," he explained. "I was asking if you two got some kinda beef going."

"Oh," Sara said simply, "No. I mean, I don't think so."

"Yea?" he asked, not quite buying in, "Just a minute ago you coulda cut the tension in here with a knife."

"Who, Cath and Princess Sunshine here again?" Nick asked, grinning as he entered the room and receiving a mock 'ha-ha' from Sara.

"Yup," Warrick replied, refilling his cup of coffee.

"No," Sara said again, "There's no tension. We're… fine. Alright?"

She stood to leave, and Nick raised his hands in surrender.

"Hey, whatever you say, Princess," he said, repeating the nickname. Sara shot him a glare and walked out of the room.

"There's something going on there," she heard Warrick say when he thought she was gone. Standing out of sight, she couldn't resist listening in on their conversation.

"Yea?" Nick asked, "What you thinking?"

"I dunno, man. But they both been acting outta wack lately."

"Yea, yea," Nick agreed, sounding thoughtful. "You look like you got a theory."

"Well, between you and me," Warrick said, lowering his voice, making Sara strain to hear, "I think Cath's been wanting to get on your "Princess Sunshine" here for some time now."

Sara thought her jaw may have actually hit the floor.

"Nah, man," Nick said. "No way."

"Way," Warrick continued. "You wanted my theory? I'm thinking they hooked up, and something isn't going quite the way they'd hoped."

Sara started to feel panicked, but resisted the urge to run, listening for more.

"That's a pretty far-fetched theory there, Rick," Nick continued to be skeptical.

"Bet?" Warrick asked

"How much?"

Oh, come on! Their betting on my sex life? Don't bet too much, Nicky…

"Hundred bucks," Warrick said. Ouch.

"You are so on," Nick laughed.

"I'm telling ya, Nicky," Warrick said again, "Cath has definitely got a thing for Sara. She's got it bad."

A "thing?" What kind of thing? Attraction? A crush? Or did he mean… a romantic thing? Before she thought about what she was doing, Sara flew back into the break room.

"What kind of "thing?" Sara demanded.

Warrick and Nick just stared at her like two dumbstruck little boys who had just been caught with their hands in the cookie jar.

Oh… shit.
