A/N: Another fill in chapter between seasons, this one involving Bela dealing with Bryce's death and Casey helping her before her spy training begins. Please review!

"Has she said anything?" Sarah asks, climbing in the front next to Casey before glancing in the backseat at Bela and Chuck. Her blood on her hands had dried, and she twisted them together as she stared blankly at her knees.

"Nothing," Chuck sighs, Casey glancing in the mirror at the two.

"She fought okay," he shrugs, turning back to the road. "Why's she like this now?"

"Casey," Sarah frowns, shaking her head at him.

"Stop talking about her as if she's not sitting right here!" Chuck yells, glaring at the two. "Just shut up!"

Casey opens his mouth ready to respond but hesitates, glancing in the mirror again.

"Here, we're home," Casey says, opening the door before helping her inside. He flicks the lights on before moving back to her side.

She growls as he wraps an arm around her, catching him off guard as she pushes him back outside.

"Leave me alone!" she yells, slamming the door in his face. He growls, storming in.

"Bela!" he yells, catching her wrist as she swings at him.

"Leave me alone, Casey!" she screams, the tears breaking free and sliding down her cheeks. "Please just leave me alone."

"I'm not leaving you alone, not while you're like this," he warns, pulling her hands flat against his chest. "I'm not leaving you."

"I want Chuck," she says, refusing to look at him. "I want Chuck to stay with me."

He sighs, releasing her before opening the door.

"How is she?" Chuck asks, both Sarah and him looking up as he exits the apartment.

"She wants you," he growls, walking past them.

Chuck stares after him confused before turning to Sarah.

"It's okay, go," she says. "Take care of her, she needs you."

"Thanks," he says before jogging inside.

He frowns when he enters, locking the door as he kicks his shoes off.

"Bela?" he calls, listening for a response. He continues into the apartment, cursing as he hears running water.

"Hey!" he yells, seeing her lying on the shower floor, her dress sticking to her as the water cascaded down over her. "Bells."

He sighs, pulling off his jacket before joining her, sitting down and pulling her against him.

"No!" she yells, struggling against him before opening her eyes and meeting his concerned ones. "Chuck?"

"I'm here," he whispers as she falls against him, his arms holding her close. "It's okay Bells, I'm here."

He kisses her soaked hair, her sobs shaking her whole body as he slides his hand up and down her back.

"I want Bryce," she cries, her voice breaking as she says his name.

"I know," he says. "I know you do, Bells."

"Thanks for coming," Chuck says, opening the door for Sarah. "And it's not what you think."

She sighs, her eyes lingering on the towel he was wearing before passing him, setting his clothes down on the counter.

"When I got here, she was in a heap on the shower floor," he explains. "I got in with her-we were both fully clothed-and I just held her until she stopped crying and then I called you when we got out. I-I-I need another favor, though. She's still dripping wet, I didn't want to-we're best friends but we've never-I've never-"

She takes it all in before nodding.

"I'll dress her," she says, resting her hand on his arm. "You get dressed and I'll be back."

"Thank you," he nods, watching as she walks up the hallway before turning to his clothes on the counter.

"Oh man, she went through my underwear drawer," he frowns, staring at the pair in his hands. They were pink, a casualty of being washed with Ellie's red sweater.

"Everything okay?" Chuck asks as Sarah joins him.

"She's dry and sleeping," she nods before frowning at her now wet attire. "Which is more than I can say for me."

"I'm sure she won't mind if you borrow some clothes," he smiles before pausing at her confused look. "What?"

"She was never this bad last time," Sarah frowns, Chuck joining her in the kitchen. "Last time she found out he 'died', she took it fine."

"I know," he says, resting his hand on her back. "But this time he's really dead, and he died in her arms. It's different."

"Yeah," she nods. "I forgot about that part."

"How are you taking it?" Chuck asks, pulling her closer. "You okay?"

"I'm good," she nods, smiling up at him. "This time I have someone who I care about much more with me."

"Really," he says, a smile breaking free.

"Really," she beams. "Oh, and I have a question..."

"Pink underwear?" he asks one step ahead. She laughs, nodding. "Laundry incident, I blame Ellie; that's why Devon does the laundry now."

"I didn't think it would have been an item you willingly purchased, well I hoped not at least," she teases.

"So, this training..." he says, the smile disappearing from her face. "What's the matter?"

"If you do this, if you go you're gonna be a spy for the rest of your life, every city it's gonna be a new mission, a new identity, and you're not gonna be the same person," she says.

"Yeah, that's a great thing," he says.

"Chuck, listen, we could..." she starts.

"We could what?" he asks.

"Company," she coughs, nodding behind them. Chuck turns, quickly straightening up at the sight of Bela standing in the doorway.

"Hey, Bells, we were just-"

"Can you get Casey?" she croaks, her voice still weak.

"Are you sure?" Sarah asks and she nods. "Okay, I'll call him."

Chuck stands up as Sarah takes her phone out, moving over to Bela.

"How are you feeling?" he asks, taking in her appearance. She looked absolutely exhausted.

She shakes her head, running a hand through her tangled hair.

"He's on his way," Sarah says, joining the two.

"Thank you," Bela nods, moving past them into the kitchen.

Chuck wraps an arm around Sarah as they watch her open the refrigerator, carefully kneeling in front of it.

She reaches out a shaking hand, her fingers resting lightly on a beer.

"No," a voice says from behind her, and her hand retracts as she lets out a breath.

She gets to her feet, closing the door before turning and wrapping her arms around him.

"Casey," she whispers, clutching at his shirt as she inhales his scent.

He kisses the top of her head, the two ignoring Chuck and Sarah's exit as he pulls her closer.

"I'm sorry," she says, her voice breaking as he feels his shirt beginning to moisten.

"It's okay," he whispers into her hair. She pulls back, and the look in her eyes nearly breaks his heart.

"I don't know what to do," she says. "Tell me what to do, Casey."

"I can't do that, sweetheart," he whispers and her face crumples again, the tears streaming freely down her cheeks.

"Don't leave me," she whispers, her eyes locking onto his. "I can't lose you, too, Casey."

"I'm not going anywhere," he says, pulling her against him.

"I think you should just shoot me now," Bela groans, squinting at the intruding light shining through the ridiculously thin curtains. "End my suffering."

"You've driven me to drink more than I ever have in my life," Casey mumbles into her hair. "So you can shoot me first, then yourself."

She looks up at him, his chest her makeshift pillow.

"You didn't think I could drink you under the table if I remember correctly," she teases, smiling at their entwined legs under the sheet. "And who proved you wrong?"

"We drank the exact same amount if I remember correctly," he says.

"Perhaps," she whispers. "But you didn't win."

"Neither did you," he mumbles.

She smiles, bringing her hand up as she brushes her hair out of her face.

"Oh, no," she whispers, staring wide eyed at the ring on her finger. "No, no, no, no, no!"

"What are you yammering on about, now?" he mutters, pulling her closer.

"Casey-Casey, wake up!" she says urgently. "You need to wake up now."

His eyes open quickly and he instinctively reaches for where his gun was usually kept-of course it wasn't there.

"What-what's wrong?" he asks, sitting up next to her.

She holds out her shaking hand, his eyes focusing on the band on her finger.

"What-why are you..." he asks slowly. "Did we?"

The two make eye contact as the night before flashes through their minds.

"This is rubbish," Bela says, staring at the machine. "It's-it's ridiculous how people waste their money on it."

"Gambling, sweetheart," Casey shrugs, watching her. "It's addictive."

"Yeah, well not for me," she mutters, standing up annoyed.

He chuckles, resting a hand on her waist.

"You're the one that wanted to come to Vegas," he says, leading her away from the machine.

"After the six weeks of hell we've been through, I think we've earned it," she says, referring to the aftermath of Bryce's death. Sarah had gone with Chuck for his spy training, Bela needing more time before she left with Casey.

"Do you want a drink?"

"You're gonna let me?" she asks, teasing.

"Look at where we are, as if there'd be any stopping you."

"Ha, ha," she deadpans and he leads her to the bar.

"You can't exactly hold your liquor," he says and she snorts.

"And when have you ever seen me drunk?" she asks, raising an eyebrow. He thinks for a moment before frowning.

"Then game on," she smirks, ordering two shots.

"Now this is more my style," she laughs, struggling to slide some coins into the toy machine.

"Thought you didn't like gambling?" he asks, his arms around her as she presses the buttons on the machine, guiding the claw to the corner.

"This is more fun than gambling," she shrugs, cursing as it comes up empty. "Dammit!"

"Looks like you're having a great time," he teases and she sighs, resting her head against the glass.

"Here," he says, moving across to another machine. He slides some coins in the slot, twisting the knob until a small container slides out. "See, on these you always win."

She pretends to be disinterested, sliding more coins into the claw game as she ignores him.

"Shiney," he says, staring at the prize. It was a small ring, and he raises an eyebrow as it lights up when the jewel on top was pressed down.

She watches him out of the corner of her eye, gasping as a small stuffed animal is picked up in the claw and dropped into the release shoot.

"Casey!" she yells, her hand banging against the glass. "Casey, look!"

He chuckles at her enthusiasm, shaking his head as she clutches the toy.

"You are drunk," he says, pulling her to him. She smiles up at him lazily, glancing down at the ring in his hand.

"Casey," she whispers, her eyes wide as he slides the ring onto her finger. He pauses, realising his actions before clearing his throat.

"Oh, it flashes," she laughs, staring down at it.

He laughs at her, wrapping an arm around her waist as they move outside.

"Can you remember where the hotel is?" she asks, resting her head on his shoulder. He nods, the two making their way down the street.

He pauses for a moment, kissing her on the cheek.

"How drunk are you?" he asks, the two staring up at the flashing lights on the building.

"As drunk as you," she grins as he takes her hand, the two walking inside.

"Hi," an overly cheerful woman greets them as they enter the chapel.

Bela grins up at Casey, the two managing to repeat the vowels with little difficulty in their intoxicated state.

"I do," he says, sliding the ring onto her finger once again.

"I do," she smiles.

"I now pronounce you husband and wife," the woman says. "You may kiss the bride."

Bela smiles up at him, both of his hands still resting securely on her hips.

"I love you," she says and he pulls her ever closer to him, crushing his lips against hers.

"We have another ceremony," the celebrant says, clearing her throat loudly.

"Okay, okay," Bela says as they pull apart, Casey quickly taking her hand again. "We're going."

He pulls her outside, the two stumbling across the road before he glances around.

"Are we lost?" she frowns, staring up at him with wide eyes. He leans down and kisses her before shaking his head.

"It's not far," he says as they continue down the street.

"I hope not," she says, glancing up at him. "Your wife wants to start her wedding night."

A smile spreads across his face and his pace quickens, his arm now snaking around her waist and pulling her closer.

"I like how you think," he says, nodding for her to enter the hotel first before following.

His hands pull her closer again as they wait for the lift, both sighing in relief as the doors open.

"What floor?" she asks, his lips sliding across her collar bone. "What floor are we on?"

She laughs as he spins her around to face him, his hand reaching behind her and pressing a button causing the doors to slide shut.

He pulls her up against him, her hands flat against the cold metal of the lift.

"Casey," she sighs as he kisses down her neck, the two quickly parting as the doors open with a ping.

He walks ahead of her, fumbling around in his pocket for their room key.

"Wait!" she cries, grabbing his arm. He stares at her confused. "You have to carry me through the doorway, it's what people do after getting married."

He chuckles, unlocking the room before throwing the key inside.

"John!" she yelps as her feet disappear from beneath her. She wraps her arms around his neck as he carries her into the room, kicking the door shut behind them.

"Isabela Casey," he says and she laughs, moving to wrap her legs around his waist.

"Is John Casey even your real name?" she hisses as he slams her against the door.

"Does it matter?" he growls.

"'Course not," she smirks, watching as he kicks his shoes off, his pants joining them.

She gasps as his hands slide up under her dress, his thumbs looping in her underwear before pulling them to the side.

"John!" she cries, her hands clutching fistfulls of his shirt as he quickly slides into her, her back crashing against the door again. "John!"

"Not calling me Casey tonight?" he smirks.

"I think I'll be calling you lots of things tonight-ahh!" she screams.

She bites her lip, throwing her head back as he thrusts into her once more.

"John!" she screams, her muscles tensing as they both find their release. She feels his head rest against her, her fingers combing through his hair as he sets her down.

His hands move around her, pulling down the zip at the back of her dress before helping her out of it. She silently moves forward, pushing him back on the bed before climbing on top of him.

"You're very willing tonight," she teases, unbuttoning his shirt. He chuckles, his hands catching her wrists before he flips her onto her back, reversing their positions.

He moves slower this time, gently kicking her legs apart before moving against her.

She moans, pulling him down to her and capturing his lips.

He pulls back, his lips sliding across her cheek before finding her earlobe, his teeth teasing the skin and causing her to shiver against him.

They say nothing, taking their time being with each other.

Her hands slide down over the muscles of his back, her fingers caressing his spine as he moves against her.

He bends his head down to her again, his lips covering hers as they finish.

He moves again, rolling over and pulling her on top of him, her head resting against his chest as she closes her eyes.

He pulls the sheets up over them, his arm wrapped around her as he listens to her breathing deepen.

"Love you too sweetheart," he whispers, kissing her softly before pulling her closer. She mumbles something before sighing, her arm resting across his chest.

"We're married," Bela says, staring up at him urgently. "Casey, ohhh, Casey."

He swallows hard, staring down at her hand again.

"Maybe it wasn't legal-it is Vegas after all," he says. "And we were very drunk last night."

"Still sober enough for them to marry us-oh my God, I can't believe this."

"We can have this taken care of," he says.

"I'm twenty eight, I can't-I'm gonna be a divorsee at twenty eight!" she says, horrified. "What are we gonna do?"

"We could leave things as they are," he says and she stares at him confused. "For the cover, Bela."

"Right. The cover."

"We're already living together, we could just say we took it to the next step," he explains.

"The next step would be an engagement," she teases before holding her hand up. "Not getting married in Vegas, with you giving me a novelty ring."

"You said you liked the ring," he mutters and she laughs, staring at it.

"I love it, Casey," she smiles. "It flashes."

"Yeah, well," he says. "I'll get you something more appropriate-for the cover."

"You don't have to-" she starts before he kisses her.

"Now, I say enough talk so we can spend our last day here doing something more fun," he smirks, rolling her onto her back.

"Right," she smiles. "Before my training."

"Before your training," he nods.

A/N: And that's the fill in chapter and yes, they're legally married. Next we have Bela completing her spy training before being reunited with Chuck and breaking the news to him. Please review!
