A/N: This is just a short fill in chapter before I start the Season Two ones. It's set a month or so after the last chapter, so Bela's gunshot and tattoo are definitely healed by now.

"Bartowski!" Casey yells, pushing open his window roughly.

"You really need to start using the phone or the front door like a normal person would," Chuck growls, glaring over at Casey while pausing his video game.

"Real funny, where's Bela?" he asks, looking around the room.

"Not here, obviously," he mutters, swallowing hard as Casey takes out his gun. "She went for a run with Sarah, they should be back soon."

"She's not healed yet, she shouldn't be doing anything," Casey growls.

"Yeah, try telling Bela that-she gets antsy when she can't work out."

"I didn't know she worked out at all."

"Have you seen what she eats?" Chuck laughs. "Of course she works out; you've seen the treadmill in her living room."

"Maybe you should join her some time," Casey says, nodding at Chuck clutching the game controls.

"Haha," he says sarcastically, standing up as he hears Sarah and Bela outside. He climbs out the window, Casey already making his way over to the two.

"Agent Walker, are you trying to kill the Intersect?" Casey growls.

"Is there a problem?" Bela asks, gaining Casey's attention as she stretches her arms up, retying her hair. His eyes travel down her body, staring appreciatively at her crop top and shorts before lingering on her tattoo.

"You're still healing," he says, his eyes moving to the scar tissue on her shoulder.

"I've been fine for a couple weeks now Casey, and Sarah said-"

"She's completely healed, both from her tattoo and the gunshot so give her a break," Sarah says, annoyed at Casey's attitude.

"Good run?" Chuck asks, trying to break the tension.

"You should join us some time," Bela smiles, Casey snorting at this. "What?"

"Told him the same thing," Casey says, Bela raising an eyebrow.

"Are you sure your shoulder is healed, it looks sore," Chuck says, turning the conversation back on Bela.

"What?" Casey says, moving closer to her.

'I will kill you,' she mouths to Chuck as Casey ushers her towards his apartment.

"Well that was mean, Chuck," Sarah says, moving next to him. He sighs and she follows him into the apartment.

"I was just defending myself... sort of," he says, offering her a water. She thanks him, downing it quickly. "Bela is healed though, she's okay right?"

"She's fine, Chuck," Sarah smiles reassuringly. "If she wasn't, I wouldn't allow her to work out."

"Good, that's good," he nods, smiling back at her.

"You're very protective of her," she says, watching him carefully.

"Do I detect a hint of jealously?" he teases, his eyes widening as she blushes lightly, only just noticeable against her flushed complexion.

"Just curious," she says and he nods, hiding his smile.

"How are you feeling, are you hurting?" Casey asks, following Bela closely into the apartment.

"I'm thirsty, but that's understandable," she says, ignoring his concern.

"Bela, would you just look at me!" he yells.

"What's your problem?" she yells back, turning to him. His eyes travel down to her tattoo again before he meets her eyes. "That again. Jesus Casey deal with it, okay?"

She moves away from him, leaning into his fridge before taking out a bottle of water.

"Do you hate it that much?" she asks, watching for his reaction. He moves closer to her, his hand running slowly up her side before resting on the ink.

"I just haven't seen it healed yet," he whispers, running his fingers over the lines. "I haven't seen you healed yet."

"You're the one that's been holding out on me," she smirks.

"Yeah, until you were healed. And now you're spending more time with Sarah than with me. How come you work out so much, anyway?" he asks, watching her down the rest of the water.

"Because I love food," she laughs, turning back to him. "One of the many things I have in common with my dad. And I've only started working out more because you won't have sex with me and I've been frustrated."

He chuckles at this, moving over to her.

"Well you're all healed up now, aren't you?" he whispers, kissing her shoulder. She shivers, her smile growing.

"I'm gonna take a shower," she says, pulling away. He smirks, moving to follow her until she stops him. "Alone."

"Alone?" he asks in disbelief.

"Now that I'm healed and I know that you want me again-"

"Hold up, you know damn well I've always wanted you, I just wanted you healed completely so I wouldn't hurt you."

"Whatever, point is it's up to me now," she smirks and he raises an eyebrow.

"It's like that now, is it?" he asks slowly.

"It's like that now," she nods, moving away before he grabs her arm lightly.

"Then by all means if it's like that, go use your own shower."

She stares up at him in disbelief.

"My shower?" she asks, frowning. "With the crappy water pressure and unreliable temperature?"

He nods.

"Fine," she sighs, grabbing the empty water bottle. "But I'll remember this."

"I'm sure you will," he chuckles as she leaves.

"What's up, why aren't you changed?" Bela asks, joining Sarah in the Orange Orange.

"I'm working longer than I thought," she says, biting her lip.

"What? You get to choose when you work," Bela says confused.

"Uh, Casey said he'd be training you today," she says, smiling nervously.

"Are you serious?" she asks, jumping slightly as Casey walks out from the back.

"Absolutely," he nods, Sarah glancing between the two.

"Fine," she groans, waiting for Casey to join her. She looks up as he moves out the back again.

"Are you coming?" he calls.

"Coming where, the freezer?" she asks confused, Sarah shooting her a smile as she walks past.

She follows him out the back, watching curiously as he opens a series of doors, some needing retinal detection she noted.

"This is, uh, new," she mumbles as he pulls her through the door.

"CIA decided to spring for new digs, finally a first rate operation," he says as she follows him down the stairs.

"Okay," she nods, looking around as Casey types some things into the computer.

She follows him down the hallways, stopping as he moves into a larger room.

"Sweet," she mutters to herself, looking around at all the equipment. Weights, punching bags, mats.

"So you ready, sweetheart?" he asks, watching her unzip her shirt.

"Hell yeah," she grins, her eyes widening as he pulls off his own shirt.

"What?" he asks, noticing her gaze.

"You're not wearing a shirt," she states, swallowing hard as she runs her eyes over him.

"Neither are you," he points out, and she glances down at herself.

"It's a sports bra, it counts," she says, pulling her track pants up a little.

"Yeah, it counts," he smirks, the two of them moving to the centre of the room.

He tosses her a pair of gloves before pulling on his own.

"You want me to hit you?" she asks and he nods. "Okay then, got some rules?"

"Don't kick me in the crotch and we're good," he says, moving into a stance.

"Got it," she smirks, quickly throwing a jab at his head followed by an uppercut as he ducks.

She blocks a punch, throwing a hook which he quickly averts before she connects with a rising knee strike.

"Not bad," he says, the two moving back into their stances.

She smirks, biting her lip before extending her leg in a hook kick. He moves out of the way before connecting her side with a half swing. She coughs before attempting a straight knee thrust towards his groin.

"I think you're enjoying this a little too much," he smirks and she laughs, brushing her hair back out of her face.

"Nah," she grins, raising her arms and moving back into her stance. "Just a little."

He chuckles, defending himself against her punches until she throws an overhand at his head, connecting hard and fazing him slightly.

He moves behind her, grabbing her quickly.

"I hold your arm like this, what are you gonna do?" he growls, pulling one arm up behind her back. She hisses, arching her back and resting her head on his shoulder.

"This isn't working," he whispers in her ear. She takes his brief distraction and throws a back fist at his head before turning and sweeping his legs out from under him.

"I think it's working just fine," she grins as she pins him down.

"Where...?" he asks as she leans over him.

"Learnt kickboxing when I was a kid, did it for years even in college," she smiles, moving to get up but he pulls her back down.

"Why?" he asks curious.

"Why not," she snorts. "You should have brought me here earlier; all of this stuff is, well, awesome."

"We've only just got set up," he explains watching her carefully before pushing her up, pulling her to her feet with him.

"Where are we going?" she asks, following him into another room.

"You need to learn to shoot," he answers, handing her ear plugs and ear muffs.

"I know how to shoot a gun," she says, staring up at him.

"You what?" he asks, pausing.

"My dad goes shooting; he took me a lot of the time. I can shoot a gun," she says, shrugging. "Mostly rifles, but I know my way around a gun."

"Show me," he says, handing her the weapon. She stares up at him curiously before taking it, putting in the plugs before he sets the earmuffs on her head.

She loads it before taking off the safety.

"Block your ears," she smirks before firing at the targets he'd provided.

"Damn it," he growls, covering his ears from the shots. He stands behind her, resting his head on hers once she's done. "I get it! You can shoot the damn thing!"

"Well I told you," she grins, lowering the weapon.

"You're surprising, you know that?" he asks, watching as she purses her lips while staring at the targets.

"Not the first time I've heard that, no," she says, turning to him. "So what now?"

"We're done," he says. "For now, at least. I'll find a suitable firearm for you to have next time."

"Huh-what? Firearm? What the hell are you giving me a gun for?" she asks in disbelief.

"To properly protect yourself."

"Properly protect myself? Are you serious?" she asks.

"You obviously know how to handle a gun," he shrugs.

"Yeah, that doesn't mean I've ever had a desire to go buy one and keep it strapped to me at all times."

"That's ridiculous," he snorts. "It'd be for you to keep in your apartment as well. You'd only have it strapped to you on missions."

"You're serious about every part of this aren't you?" she asks and he nods. "Well, what about Chuck?"

"What about him?" he growls.

"Are you going to train him to use one?" she asks.

"Give Bartowski a gun?" he asks and she smirks, nodding. "Plus if he needs training, Walker can take care of it."

"That's not a bad idea, actually," she says, smiling to herself.

"What are you talking about?" he asks as they walk back to the other room.

"Sarah and Chuck?" she smiles. "A little quality time together would do them good."

"No," he says, shaking his head. "Absolutely not, ain't gonna happen."

"You know complain all you want about Chuck's feelings but you're doing the exact same thing, just… minus the feelings," she says, picking her jacket up off the floor.

"Wrong," he says, pulling his shirt on. "I'd never let this compromise your safety."

"But don't you think that because of what we have, you're even more alert at protecting me?" she asks.

"You're talking too much again," he says, pulling her to him. She smiles against his lips before pulling back.

"Are you coming with me?" she asks, zipping up her jacket.

"Got work to do," he says and she nods.

"See you, then," she says before smiling as he pulls her back.

"See you later," he whispers in her ear before releasing her.

"Thought you'd be at my place," Casey says, walking into Bela's apartment.

"Eh," she shrugs, sitting on the counter. "I had to shower, which I now apparently have to do here."

"What are you eating now?" he asks, ignoring her comment as he joins her in the kitchen.

"Frozen yoghurt," she says, watching him from the counter.

"That's not food."

"Yes it is," she argues. "And it's free food."

"You took it from Sarah's work?" he asks.

"Of course not! She gave it to me, for free."

"Just like at the Wienerlicious."

"Hey, I paid for some of those wieners!" she frowns.

"You can't live on food from every place that Sarah works," he says.

"Unless she gets a job at a Subway," she mutters to herself, smirking at the idea.

"Well, at least you're not drinking anymore," he says and she frowns, glaring at him.

"Not by choice," she mutters and he moves over to her, resting his hands on the counter either side of her.

"You really miss it that much? Going out and getting drunk, waking up with men you've never even met before?" he asks before sighing. "Or are you just sick of waking up with me?"

She stares at him, taken aback by his words.

"Casey, no," she says, shaking her head. "Of course I don't miss that, and I don't regret anything with you, either."

"Then what?" he asks, quickly becoming annoyed.

"Sometimes..." she starts, pausing for a moment to think. "Sometimes I just miss going out, forgetting that I have all these secrets in my head that people want to lock Chuck and me up and study us for. Sometimes I miss being normal, is all."

"You are normal," he whispers, moving closer to her.

"Yeah, well I don't feel like it all the time," she mumbles before his lips cover hers.

"You do to me," he says, causing her to smile.

"You're showing your feelings, Major," she says, smirking as he clears his throat.

"Just needed to clear that up, for the cover," he says, frowning.

"Mhmm," she smiles as he slides his hands up her thighs. "That for the cover, too?"

"'Course," he nods as she tosses the empty yoghurt container in the sink, her arms going around his neck as he lifts her up. "You giving in?"

"Not if you say it like that," she teases, pressing against him.

"You like to win, don't you," he smirks as he carries her down her short hallway and into her bedroom.

"Depends on what we're playing," she grins, laughing as he tosses her on the bed.

"That tattoo does some interesting things when you move," Casey says, watching her as she climbs off of him.

"Oh, you like it now?" she laughs, shaking her head.

"I could get used to it," he shrugs, rolling over to face her.

She snorts, punching him lightly before closing her eyes.

"You can work out with me, you know," he says, trailing his finger across her tattoo.

"I like working out with Sarah, gives us a chance to talk," she smiles.

"Oh really, and what is it you talk about?" he snorts.

"That's between Sarah and me, isn't it," she grins, opening her eyes and meeting his. "But I'll admit I did enjoy our little workout just now; and before."

"And?"

"And maybe I could work out with Sarah sometimes and you the rest of the time," she says. "You know, when I'm not exhausted."

He chuckles, pulling her even closer to him.

"Alright," he nods, grabbing her sheets and pulling them up over them both.

"Alright," she mumbles, her eyes sliding shut before his do the same.

AN: Sorry for all the kickboxing jargon. Basically they just did a lot of punching and kicking, lots of fun for the two of them. Anyway that's the filler chapter between seasons, so next it's the first season two chapter.
