Kensi smirked to herself as she caught him at it yet again. That was the third time in nearly as many minutes. And they hadn't even been in here long! You'd think he'd at least try and pretend to be productive.

Deeks was supposed to be lifting weights while she did some yoga and practiced her punches but there hadn't been much of that going on at all. Oh, sure, he was on his back and technically had a weight in both hands but Kensi didn't think that he'd gotten past ten reps. It had certainly spent more time on his chest than actually moving. He was probably going to have an indent on his chest from where it was at the end of all this.

He thought he was being all cool and subtle but, let's be honest, when had Marty Deeks ever been subtle? Especially when it came to flirting? Because that's what he'd been doing, giving her all these flirty looks and looking her up and down. Quickly, mind you. Trying to make sure that she didn't pick up on it but guess what? She did. Like she said, he wasn't exactly being subtle about all this.

Okay, now he wasn't even trying to be subtle about checking her out. She could feel his gaze burning into her skin. She forced and stretched just so and was rewarded with a muffled groan from her partner. Kensi held back her grin with some effort so as not to give anything away. This was far too fun.

"Are you quite done at looking at my ass?" Kensi finally asked, making Deeks started slightly.

Thankfully, she had timed it so that he wasn't holding the weight in the air.

"What? I mean, I wasn't- well, I- you have a nice ass," Deeks said defensively.

"Did you really think I wouldn't notice?" She teased.

"Au contraire, I think it took you too long to notice."

"I've noticed it the whole time."

"And you just ignored me?" He said, his whole tone changing from teasing to indignant.

She just grinned at him, happy to give back some of what he dished out to her.

"Maybe."

"That's just mean!"

"Oh, really?"

He pouted at her. "It is."

"Come on," she said with a fond eye roll, throwing one of the focus mitts at him. "You may as well be doing something useful."

Deeks chuckled at her and caught them easily.

"You aren't going to punch me in the face like what happened to Callen and Sam?" He asked suspiciously, putting the mitt on.

Kensi rolled her eyes. "Not if you pay attention."

"I think you'll find that you're the one should be paying attention. Particularly to where your fists are going."

"Don't tempt me."

She punched her fist into her open palm to make sure that everything had been put on correctly. Felt good. Right, she was ready.

Lifting her fists up in front of her, she indicated to Deeks to put the pad in the right place.

"You know," Deeks took a step back. "Maybe this isn't a good idea."

"I'm not going to deck you in the face, okay?" She finally said in exasperation.

"Yeah, well, I don't want to take any chances," he said, continuing to walk backwards. "I mean, my face is my best feature-"

The next few seconds weren't anything that either of them could have predicted.

Deeks caught his foot, somehow, in the weights he'd set down. And he didn't just stumble, he fell. Backwards. Onto the other weights. There was a sickening 'crunch' noise.

"Deeks!" Kensi dropped to the ground next to him, a panicked look on her face.

I'm fine, I'm fine. Seriously, I'm fine," Deeks tried to reassure her but it didn't work.

That was quite the fall he had taken. And she had seen that wince, he had definitely hurt something. The question was where? It wasn't his head, he wasn't holding or touching it. Which was very lucky of him, considering how he fell.

"What on earth happened in here?" Hetty asked, only seeing Kensi crouched over Deeks with a worried look on her face.

"'M fine," Deeks mumbled, trying to sit up.

But he was stopped by Kensi's hand on his chest.

"No, Deeks, your back might be injured."

"My back is fine."

"We don't know that, Mr Deeks," Hetty backed Kensi up. "Please lie still until we assess the situation. Did someone call an ambulance?"

That made Deeks try to get up again with only a stern look from Hetty making him stop. He lay back down with a frown, trying not to wince as the movement actually did jar his back.

"I am not going to the hospital just because I tripped over my own feet," he told them.

"Yes, you are," Kensi informed him, beating even Hetty to it. "You've wrecked your back and you might have a head or neck injury!"

"Now who's being the dramatic one?"

Kensi didn't even bother saying anything and instead just glared. Thankfully, it made him shut up.

"I will phone for one," Hetty said, standing off to one side to do so.

"Is it true? Did Deeks really hurt himself while walking?" Sam asked almost eagerly as he and Callen came into the gym a few minutes, faces eager and full of morbid curiosity.

They paused and their eyes widened in shock when they realised that Deeks was on a stretcher and this could very much be serious.

The ambulance had arrived pretty quickly. Kensi wasn't sure how Hetty managed that but then again, this was Hetty.

"It wasn't while walking," Deeks complained.

"Sir, I'm going to have to ask you to stay still," the paramedic told him.

"I'm fine," but he did as he was told.

Mainly because everyone was either glaring at him or giving him pointed looks. He couldn't win when everyone was against him.

"What I would like to know is why the gym always seems to attract incidences like these?" Hetty asked in exasperation.
