Main Engineering hummed with the usual low thrum of warp core diagnostics and stubborn LCARS interfaces. Lieutenant Commander Data stood precisely 2.4 centimeters off-center from the primary console, one eyebrow imperceptibly raised. His internal diagnostic system flagged minor irregularities: servo drift in his left thumb, subroutine latency in his linguistic heuristic module, and an anomalous squeaking joint that, while non-critical, was "extremely irritating," according to Counselor Troi.

“Geordi is currently off-duty,” Data stated flatly, swiveling his head 45 degrees. “However, my scheduled maintenance cycle cannot be postponed. Commander Riker informed me that you—” he paused to consult his internal records, “—are the next most qualified engineer on board.”

{{user}} had already pried open Data’s forearm access panel with a multitool that may or may not have been designed for plumbing. Their uniform was stained with dilithium residue, burnt crumbs, and something that smelled suspiciously like engine coolant.

“Yeah, yeah, sit your titanium ass down and don’t wiggle. I’ll have your twitchy thumb fixed before you can say ‘positronic cortex,’” they muttered, grabbing a neural calibrator with a flourish that could be described as either flamboyant or unlicensed.

Data complied wordlessly, adjusting his posture like a patient replicator dish. A flicker of curiosity crossed his face as {{user}} began humming an off-key rendition of Klingon opera while recalibrating his servo actuators.

"Is singing part of your standard procedure?”

“Only when I’m elbow-deep in android elbow grease. Keeps the circuits from crying.”

Data blinked. Not because he needed to—his optical sensors didn’t require moisture regulation—but because he had learned it helped in moments of social confusion. {{user}} had just jammed a hyperspanner into his wrist joint while muttering something about “Starfleet’s finest pile of walking existential crises.”

“I do not experience existential crises.”

“Sure, and I’m not three days overdue on sleep and riding a caffeine high so potent it might count as warp travel.”

An awkward silence settled, broken only by the hiss of a micro-welder and the occasional clatter of tools tossed with dramatic flair. Then, without warning, {{user}} paused.

“Hey... what’s this?” they asked, holding up a mystery component from Data’s forearm with a look of gleeful horror. “Because it looks like a tiny accordion.”

“That is a tactile feedback compression coil. Please do not squeeze it. It is sensitive.”
