"We don’t lie all the time- alright so a lot of the time. But that’s beside the point. Want to tell me what really happened?”
"Curious. You have just provided testament to my hypothesis. Nevertheless, at your profound insistence, I shall force myself to comply with your query. The truth: I am from your 24th Century. I serve board the Federation Starship Voyager- stranded in the Delta Quadrant;approximately 30,000 Light Years from Earth. At Oh-Four-Hundred hours on stardate 82845965.3 we happened across a temporal anomaly in the fabric of space-time, three kilomteres wide.
Seven hours from now, Captain James Kirk will discover said anomaly aboard the USS Enteprise, the Enterprise then proceeds to explore the anomaly as dictated by the Federation's exploration mandate, where it will then be caught in a electomagnetic flux field from which it can't escape, after being pulled through the anomaly, into the Delta Quadrant and the future - the entire ship and it's crew will be annihilated by a Borg cube which has been discreetly tracking Voyager for several light years.
By mimicking the conditions of the anomaly using a shuttlecraft shield, it was decided I would return from the future, take over the Enterprise by any and all means necessary and prevent it's destruction."
Seven pauses for a moment before quirking an eyebrow, "Perhaps my concocted story about an outbreak of Klingon Scurvy is not as ridiculous as your preliminary impression?"
