Author's Note: Sorry if I'm updating too fast! I'm kind of on a roll here. The ideas just wouldn't stop coming today. Hopefully I'll keep writing this fast until the end of the fic. :)

Jane tilted her neck to the side, analysing the spot where her bird tattoo was hidden under a ton of theatrical makeup. The last time she'd gone undercover, she'd hidden her tattoos, and it seemed like a good idea to continue the tradition. The idea was to blend in, and the tattoos were a stellar way to ensure that she stood out.

As she wrestled with the zipper on the back of her dress, she cursed the fashion designer who'd come up with it. Who thought making clothing that someone couldn't put on by themselves was a good idea? Not only that, but she had no pockets. Next time she had to go undercover, she was wearing men's formalwear.

A second later, Weller approached from the back of the locker room. She hadn't realised he was in here.

"Need a hand?" he asked, meeting her eyes in the mirror.

"Uh…sure."

He wasn't wearing a tux this time, but he'd chosen a black suit with a white shirt—unusually traditional for him—and a black tie to match. He looked…

Oh, you might as well admit it. He looks fantastic.

She dropped her gaze as he stepped up behind her, hoping he hadn't seen her appreciative perusal. A moment later, his gentle touch just below her shoulder blades sent goosebumps flowing over her skin.

"Hang on. It's stuck."

Her breath caught as he slipped a finger inside the dress, repositioning the zipper from within. His light touch against the bare flesh of her spine made her shiver. After a slight tug of the fastening, it began to move upwards, but he didn't take his finger out of the dress, sliding his knuckle all the way up to the nape of her neck before releasing the small piece of metal.

"There you go," he said softly. "All set."

"Thank you," she murmured, hoping she wasn't as obviously aroused as she looked. Chancing a glance up into the mirror and accidentally catching sight of his heated gaze, she knew she'd given herself away. "Weller…"

He moved in closer behind her, resting his hands on the counter on either side of her, boxing her in. "You look amazing."

Before she could react, he brushed a light kiss against the nape of her neck. It was barely even tangible, a ghost of a kiss, yet it sent a bolt of sensation all the way down her spine to pool in her pelvic cradle. She lowered her head without even realising it, giving him easier access even as she half-whispered, "You'll rub off the makeup on my tattoo."

He kissed her nape a second time, more firmly, then trailed his lips around to the right side of her neck, avoiding the concealed oil derricks and bird tattoo completely. "No," he said, breathing the words against her ear, "I won't."

Jane shivered as his stubble brushed lightly over her skin, tilting her head to accommodate him. He pressed an open-mouthed kiss just behind and below her right ear. Oh, God, his tongue… "Why are you doing this?" she asked, wishing her voice didn't sound so husky.

His next kiss made her eyes flutter shut and her toes curl. The next made her breath tremble and her lips part. She was completely out of her depth, her thoughts hazy, her underwear soaking as her body anticipated what might be coming next.

What was not going to be coming next, because they were about to head out on an undercover mission, and he was the deputy director of the FBI and he could not be caught nuzzling her neck in the locker room like a teenager with no control over his hormones—

He seemed to reach the same conclusion, because he gave her one more slow, clit-tingling kiss on the neck before stepping back. Jane opened her eyes in time to see him adjusting the front of his pants, and that didn't help her composure the slightest bit.

Then, as she stared at him from under eyelids heavy with desire, he gave her a quick, startlingly sexy smile and left the locker room. Jane was left to gaze at her own reflection, stunned by what had just happened.

At least he hadn't rubbed his hard-on against her ass, she thought, as she opened the small black box, containing ear comms, that he'd left next to her on the counter. She didn't think she could have controlled herself if he had.

Kurt had to spend a few minutes in the men's room, cooling down, after he'd left Jane alone in the locker room. It had started as an impulse when he'd noticed her reacting to his innocent touch, when he'd been fixing the alignment of her zipper. She'd shivered a little, goosebumps rising on her skin, and he'd been unable to help but push his luck, reacting to her obvious arousal despite every professional instinct telling him not to.

When he'd started contemplating slipping his hand under her skirt, he'd pulled himself away with an effort, leaving Jane speechless and half-panting with need. God, what had he been thinking? How was he going to concentrate on this mission now?

Once he'd finally gotten his cock under control, he headed out to SIOC, where most of his people were already congregated. Jane arrived just after him, from the opposite direction, and he avoided looking at her, afraid the whole team would be able to read him like a book.

"Everyone got their comms?" Patterson asked, checking the gadget hidden in her purse. "Aaaand…we're all linked up. I'll switch us on when we get closer to the museum."

"Let's get going," Weller said, and headed for the main elevator.

As they waited for it to arrive, Zapata gently teased Patterson about her makeup, though Weller couldn't quite make out the phrasing.

In response, Patterson laughed. "Say what you will, but look at us. We are a whole bunch of very sexy people. Right, Nas?"

"We're not bad, are we?" Nas agreed, sounding amused.

"Maybe we should go out on the town after the gala," Zapata suggested. "I bet we'd all go home with dates."

"I don't need a date," Patterson said.

"You and Borden are going well, then?" Reade asked.

"Wait, you're dating Borden?" Jane asked, as they all stepped onto the elevator.

"Sssssh!" Patterson told Reade, with a huge smile that belied her words.

"Sorry. I didn't realise that was top secret," Reade said sarcastically.

Weller listened to his team banter with a slight smile. For the first time since Jane's return, they all seemed fairly at ease with each other. Nas caught his eye and smiled, as though she could tell what he was thinking, and he gave her a slight smile in return.

The gala was filled with people with more money than sense, some of them dressed in outfits that probably cost as much as Kurt's yearly salary. At least they were all there to donate money to a good cause.

He dispatched his team in pair to various floors of the building, keeping Jane with him. After a speech by one of the gala's organisers, he and Jane hit the second floor and split up by unspoken agreement. Jane was on high alert now, the way she always was on a mission. Despite their earlier interaction, there was no awkwardness or subtext between them as they exchanged a glance.

A few minutes later, Jane's voice came over the comms, but she wasn't speaking to anyone on the team. Weller doubled back to find that the guy who'd given the speech before had zeroed in on her. Hitting on Jane, or just hoping to entice her to open her purse for his cause? It was hard to tell.

Instead of extricating herself from the conversation, Jane engaged the man—who'd introduced himself as Oliver Kind—with a question about Lake Aurora. As Kurt prompted her to move on via their comms, he realised that the Clean Water Initiative would be a source of information that could potentially give her a lot of information about the lake and its ecological disaster. Even so, now was not the time or place. They were busy looking for an intruder.

When Kind tried to make Jane laugh, and she looked down at the floor with a distinctly flirty undertone to her body language, Kurt decided he'd had enough of standing by. He stepped up beside Jane and tried to steer her away, avoiding Kind's attempt to get him to introduce himself, but gritted his teeth when Jane lingered with the guy.

"My brother isn't great with people," she told him apologetically.

Seriously? Her brother? That's what she's going with? Kurt checked his glower when he realised he was probably projecting a territorial vibe to the people around them. It wouldn't help them find the person trying to infiltrate the gala if he and Jane were drawing too much attention.

Kind gave Jane his card and suggested they pick up their conversation later.

He's interested in more than her charity donations. But there's no way she'd be interested in that guy. Right?

Jane's expression dropped from a friendly smile to annoyance as she reached Kurt's side.

"What was that about?" he asked her.

"Blending in," she said tersely, as if he'd overstepped his bounds.

He was her boss and her lover, and he was well within his rights to… He backed himself down with an effort. "Just focus on this mission."

Soon after, things started to kick into gear, and he had no time to worry about Jane's interest in Oliver Kind. A failed attack on Patterson and two dead bodies later, Jane confirmed she was on the killer's trail. Two floors above him.

Weller headed for the stairs, his heart pounding. This woman was using Shadowcat's game mod to maximum advantage. She could get the drop on Jane with her thorough knowledge of the building's layout.

Various thuds and grunts through the comms signalled that Jane was holding her own, but a crash of glass made his pulse spike. If she'd thrown Jane through a fourth-floor window…

Metallic clanging now. Were the two women having a sword-fight? It sure sounded that way, and if Jane still needed to go easy on her arm, she'd be at a disadvantage. Hang on, Jane. I'm nearly there.

The sound of an explosion, loud through the comms and more faintly up above, stole Kurt's breath.

No. Jane…

He reached the Asian Art wing to find her dazedly pushing herself up from the floor, one hand clutched to her head.

Alive. Thank God.

"Jane, you okay?"

She didn't look good, her voice slightly slurred as she tried to focus on him. "I'm okay. It was just a flashbang."

Flashbang or not, she clearly needed medical attention. He pulled her to her feet, supporting her lower ribs to avoid wrenching her arm, and she swayed against him, her arms going around his neck for balance.

Supporting her, Weller issued instructions to the rest of his team, but Nas quickly confirmed that their target had made her escape.

Two people were dead, Jane and Patterson had both been attacked, Reade had used excessive force on a museum patron who'd turned out to be innocent, and they were no closer to finding out what the woman had been after—or if she'd gotten it. He cursed under his breath and began to steer Jane towards the elevator. "We need a medic for Jane and Patterson."

"I'm fine," both of the women said in unison, Patterson's voice tinny through the comms, Jane's weak at his side.

"The hell you both are." Weller rolled his eyes.

"Medic dispatching," Zapata said.

"Okay, let's get forensics in here. Witness statements. IDs on the bodies. Security footage. The works." Weller continued issuing commands automatically, the bulk of his attention on Jane. She was looking more clear-headed now, and was able to stand straight, but she had a hell of a bruise developing on one side of her jaw.

Maybe later she'd let him kiss it better.
