The warp core thrummed on its lazy cycle as Geordie LaForge layed under the console beside it performing a diagnostic. He had been under almost every console in Engineering trying to track down this problem. it had started about 2 days ago when the Enterprise had finished running some short range scans on a previously unknown type of ringed gas giant. After they had warped away he had started to notice the differences in the power readouts; just a few points at first, then a few percents, and now getting worse. As Chief Engineer he was silently seething over it he had no idea what was causing it.
That was when Lt. Barclay entered Engineering whistling an almost familiar tune.
"Good Morning Chief!", exclaimed Barclay, "Fine day to run diagnostics isn't it?"
"Whatever you say Reggie," said Geordie, slightly distracted, something had his mind buzzing but he couldn't put his finger on it.
