This prompt was given to me by OSP Manager, ("What did Hetty make you do?") and I will admit, it took me longer than I would've liked to come up with the "do." I hope this is satisfactory.

...

When Callen walked into the bullpen that morning, he was rather pale and shaky. He settled unsteadily down in his chair, breathing heavily.

"You okay, G?" Sam asked, brow furrowed as he glanced up from his laptop.

"I will be," Callen replied, rubbing his upper arm. Sam raised an eyebrow.

"What's going on?" Sam asked, scooting his chair back.

"Hetty made me do something I will never do again," he said quietly, leaning back in his chair, trying to swallow the nausea rising in his throat.

"What did Hetty make you do?" Sam asked, standing up and walking to him. "Are you alright?" He placed a gentle hand on his shoulder, worried about how pale his partner was.

"Get a flu shot," Callen replied after a moment, tugging up the sleeve of his t-shirt, showcasing the bandage stuck to his upper arm. Sam stepped back, and snorted.

"That's why you look like you're going to vomit?" Sam asked with a skeptical raised eyebrow, crossing his arms over his broad chest. Callen gave a queasy nod, swallowing hard. He rubbed at his arm subconsciously.

"Woah, Callen, you don't look good," Kensi quipped as she entered the bullpen, bag slung over her shoulder. "What's going on?"

"Yeah, man, you alright?" Deeks, behind Kensi, asked. Callen didn't answer, just took another shaky breath.

"Hetty made him get a flu shot," Sam said with a smirk, the teasing tone in his voice evident.

"Hey, it's not funny, man," Callen snapped, opening his eyes to glare at Sam.

"I'm with Callen on this one," Deeks piped up. "Needles suck."

"You guys are such babies," Kensi quipped as she sat down at her desk, setting her bag on the floor. Sam nodded in agreement. Deeks frowned at her as he walked to the coffee cabinet in the alcove, pouring water from a pitcher into a paper cup before bringing it back to Callen, who took it gratefully.

"Why'd she make you get the shot anyway?" Deeks asked, backing up and leaning against the edge of his desk.

"Said I have a habit of getting sick," Callen replied after taking a sip of water. His color had started to return.

"She has a point," Kensi spoke up, and Sam nodded in agreement.

"Flu shots don't work," Deeks said with a snort.

"You're just saying that because you don't like needles," Sam replied, shoving his shoulder good-naturedly.

"Hetty seems to think they work," Callen said as he sat upright.

"Hmph," Deeks muttered.

"Oh, don't worry, Mr Deeks, you're next!" Hetty called, suddenly appearing in the bullpen's gate. His eyes widened as she came at him with a syringe. Deeks hit the floor.
