A/N: Ah, the dysfunctional family that is the Tempest crew… :P

The first clue Lexi had that something was amiss was when she heard a dull thud from the galley followed by both Drack and Liam roaring with laughter. She wasn't sure why, but her doctor-sense (a name Sara had given to the almost preternatural sixth sense Lexi had for instantly knowing when the Pathfinder was causing mischief) tingled. She lifted her head suspiciously, ears straining to catch further sounds. Hearing nothing else she deemed herself paranoid and went back to reading her datapad, leaning back in her wheely chair and setting it spinning lightly by nudging her foot against her desk.

And then Sara's voice, muffled by the walls between them, joined the sound of the boys laughing and Lexi knew, she just knew, that the three of them were up to no good. She closed her eyes, taking in a deep breath through her nose and huffing it out in a sigh as she tossed her datapad onto the desk and rose from her chair to cross the medbay. The doors hissed open and she swept through them, heading across the corridor to the doors opposite which parted to allow her into the galley.

The laughter immediately stopped.

Lexi glanced around the room, taking in the scene in seconds. Drack and Liam stood at the counter across from her while Sara sat slumped in a chair at the table in the corner, holding her head in her hands.

Liam coughed and averted his gaze from Lexi's suspicious stare. Drack gave a toothy grin.

"Uhoh..." The ancient krogan rumbled, looking anything but concerned for the situation. Instead, he looked thoroughly amused.

Sara looked up at Lexi in a daze, a prominent red lump showing on her forehead, easily visible against her fair skin.

"Do I want to know the specifics?" Lexi demanded, moving straight to Sara's side to check her injury.

Liam cleared his throat awkwardly and Lexi looked over her shoulder at him. "I, ah… may have dared Ryder to headbutt Drack..." He admitted, rubbing the back of his neck and looking anywhere but Lexi.

"Liam!" Sara whined as Drack started laughing again.

"Kid's got a mean headbutt for a squishy!" He said proudly.

"Nakmor Drack, if you've given the Pathfinder a concussion...!" Lexi warned.

"I'm just toughening her up," Drack growled, a chuckle rumbling in his chest.

"By breaking her head?" Lexi demanded. Drack just grinned. "You know her skull recently had a hairline fracture?"

"I'm fine," Sara insisted irritably, pushing Lexi away.

"You're an absolute nightmare, Ryder," Lexi grumbled, turning back to her patient. "You know that, right?" She gently tipped Sara's chin back to look into her eyes, holding up one finger for the Pathfinder to focus on.

"Yes, mistress," Sara muttered, glaring as she dutifully tracked the raised finger. Liam snorted behind Lexi, then began coughing into his fist in an attempt to cover it.

"What?" Lexi sharply demanded of Sara.

Sara stilled, blue eyes wide as she met Lexi's slightly irked stare, then offered her most innocent smile, which, for Sara, was strangely angelic. "Nothing!"

Lexi wasn't fooled, but didn't press the matter. "It's like you're determined to give me a heart attack. Was your father this reckless?"

"Clearly," Sara drawled sarcastically. He had, after all, interfaced with unknown alien tech and sacrificed his life to save his daughter.

Lexi pursed her lips. She deserved that, she supposed.

Lexi sighed and stepped back from Sara. "You're lucky you just have a bruise."

"You mean... I'm fine?" Sara asked with a little smirk.

"Yes, Ryder," Lexi replied a little tersely. "You're fine."

"Like I said I was?" Sara pushed smugly.

Lexi fixed her with a frosty stare, to which Sara responded by twitching one eyebrow.

"No more headbutting," Lexi said finally, turning her gaze to Drack. "No more dares or bets." Liam looked away, eyes darting guiltily to Sara. "I'm sure you've heard the saying 'it's all fun and games until someone loses an eye'?" She shot Sara and her bruise a pointed look.

"Ryder's harder than she looks," Drack rumbled indifferently, folding his arms.

"She's not indestructible," Lexi shot back.

"She's sitting right here," Sara muttered moodily.

Lexi gave Sara another look, softer this time. "If you get a headache, or start to feel sick, come and find me, okay?"

"Sure thing, doc," Sara nodded.

Lexi paused a moment, watching her, then turned to Liam. "You make sure she does."

Liam nodded vigorously. "I will."

And Lexi knew he would. She could, at least, count on him for that.
