Lets say you finished a long day at whatever you do, and your off to bed for the night. You go to sleep and..............
You wake up the next day in a strange bed, not only a strange bed, but you see Q sitting across from you with a bog smile. And he says:
" So you thought it was all a game or a Show on yout primitive dum down box? Well my new friend, You wanted the trek life, lets start it now. Your on the USS Enterprise, the crew is what you seen on the show you call TNG. But this crew isn't what you seen on that show. Now try to stay out of trouble will you, and don't be boring. "
With that he pops away before you can ask any questions, and your still in whatever night wear you had on. Up get out of bed, and the next thing you hear is. Intruder alert! Intruder alert! And a very loud alert ringing.
So, doing put into this situation by Q, what would you do next? Mind you your the same person you are now, you didn't gain skills to do anything in this time, your a person out of time, but you have one thing. Insight to what MIGHT happen on the Enterprise.
What Q didn't tell you, just by putting you on the ship, somethings changed from what you seen or know, but the main events are unchanged.
So what's yout next move? And no you can't make Q send you home. He will after he is done with you, that could be days, weeks, months or years, or maybe he will never send you home.
(Oh BTW this is the Far Point mission the very begining.))
I wouldn't worry, because Troi would know I was telling the truth about the situation, thus would then get Picard's hospitality, rather than Worf's brig. First thing I would do once free to do as I pleased? head to sickbay and ask Doctor Crusher out for dinner
While I'm at it:
-- Institute much stronger computer security measures.
-- Send all civilians without a mission-related purpose aboard ship (i.e. children) home. They have no place aboard a ship that gets into mortal danger every other week.
-- Have all the so-called "manual overrides" ripped out and replaced with ones that are actually manual.
-- Order the laboratories to use physical boxes for hazardous materials storage instead of force fields. Ditto the brig, which should have actual doors.
-- Assign a security detail to any and all guests we receive for as long as they're under my roof. This is for their protection as much as to prevent Lore from impersonating Data.
-- Assign the physical sciences lab to develop lightweight body armor.
-- Actually listen to Worf when he has a relevant suggestion, like raising shields or increasing our alert level.
Say that Q did it and that I'm from the future. Then try to get my bearings and hope that something happens soon that I have some insight on.
The events of the enterprise doesn't happen day after day after day. The whole scenario is preposterous, you'll probably get thrown into a secured medical chamber and get tests run on you till they are sure you aren't a saboteur.
I know alot about a little and a little about alot
I'd order a planetary bombardment as punishment for being so squeamish. I'd tell Picard that he needed to toughen up his crew because a day will come when they will need to act more like Cardassians and less like daisy pickin vegetarian hippie humans.
If anyone questions my decision I'll yell that they need to respect their elders heck I'm probably Pickard's great great grandfather. Just do it and blast the nearest inhabited planet.
You neglected to mention: am I the Captain or am I Ensign Redshirt?
Because if I'm supposed to pull off the Picard Maneuver, no problem. I like tea. Earl Grey. Hot. And Shakespeare. And older women...
But if I'm Ensign Redshirt, I'mma putting in for additional tactical training and becoming Worf's best friend.
Just as long as I'm not the guy in the miniskirt.
Whatever's different, short of a chain of command of stubborn, targ-headed House of Duras Klingons running the ship, makes no difference. I know how Picard handled the situation with Q, and I know how to reveal the secret of Farpoint. Those are main points, which by the OP definition remain unchanged. Even if I'm a grunt, I'd be finding a way to put that knowledge to work immediately even if through the chain of command.
Farpoint, in effect, is a bit like knowing the ending to Myst. With foreknowledge of the all-important secret, its no challenge, you go straight to the secret and reveal it.
